Video Transcript for Timbren Vehicle Suspension TA25722-90P00 Review

Speaker 1: Today we're taking a look at a Timbren 1/2 inch Spacer for raised frame vehicles. Timbren recommends that you have a 1/2 inch to an inch of clearance between the Timbren and the contact point when the vehicle isn't under a load. If the clearance is more than what's recommended, then a spacer is the ideal solution. It installs easily and allows you to have full function of your Timbren suspension system even though you have a vehicle with a raised frame. This particular spacer measures a 1/2 inch thick. Top to bottom is 1/2 inch.

The hole here in the center will accepts 3/8 inch diameter hardware.Remember that you may need longer hardware since you're adding the spacer to your setup. You can go to your local hardware shop and pick something up. That's exactly what we do when we install these on customer vehicles here in our shop. When it comes to the overall diameter, edge to edge we're looking at four inches. With this part number you get one spacer.

I also want to mention that we do offer this in a one inch thickness with part number A25723-90AH00. You can view that right here at That's gonna do it for today's look at the Timbren 1/2 inch spacer for raised frame vehicles.

Timbren 1/2" Spacer for Raised Frame Vehicles - TA25722-90P00

Average Customer Rating:  4.8 out of 5 stars   (48 Customer Reviews)

1/2" Spacer fits vehicles with raised frames.


Worked perfectly for my slightly lifted F150. Without, the bed would drop a bit too much before engaging the overloads wich raised the front enough to cause mild drivability issues.


Have had them for a year along with the Timbren SAS and have hauled a camper about 9000 miles without an issue. They really stabilize the load on my 2500. You go from white knuckling to actually enjoying the drive. Well worth it, and an easy install!


The wrong spacer was ordered and Danielle was helpful with getting that order cancelled and a the correct part sent. Unfortunately, and unbeknownst to us the part had already been picked and sent down the chute so I ended receiving both sets. But Danielle saved the day by emailing a return label, which made it a simple process to get the wrong set returned.
The Spacers themselves were pretty easy to install and closed the gap between the Timbren Spring and the axle contact point to where it will engage sooner. They, the Timbren's, were doing their job before adding the spacer but I was looking for a little less squat when the trailer is connected and by adding the spacer was able to achieve it.


They work like they are supposed to. I used them in conjunction with my timbrens to take up some gap on them. For reference to those with an at-4 GMC, I have a 2020 and with this 1/2" and the timbren (it was actually only 4 1/2" tall, not 5" like the images showed) have about 1.25" gap between the bottom of the timbren and the axle stop. I was under the impression that the timbren itself was 5" based on the image in the kit I got, tgmrck15s, so I'm a 1/2" shorter than I wanted but I will run it for a while and see how it looks when loaded with my trailer before going any thicker with a spacer.


These came quickly and were very easy to install after I finally figured out what wrench was necessary to remove the factory jounce bumpers. A 10 MM socket was what it took.



They help keep my Denali 1500 from sagging so much when I tow my car hauler with the car in it.


Good product, does exactly what it is designed to do. The only words of wisdom I can pass on are to make sure it is not riding to close to the axle when your truck is empty or it will kick and have a rough ride (when empty only). This space can be adjusted by adding or removing the spacers. You can see in the picture that I have about 1.5 inches of clearance on my setup. Once the truck is loaded and they are in use they perform beautifully. Definitely helps reduce sag and supports the load evenly from side to side. 2018 F150 XLT FX4


I used the spacers after checking measurements before installation on my GMC 2021 Sierra 1500 AT4. More information in my review of the full enhancement system to follow.


I am very happy with the performance of Timbrens on my 2014 Ford F-250. When unloaded and not needed, the Timbrens sit idle, but when I hitch up my 7000 lb trailer, the Timbrens provide additional support to the stock springs which results in better rear end stance and better handling while towing. I think it makes my F-250 more like a F-350 when towing.

Because the original Timbrens installed were about 1 and 1/2 inches from the axle, I added the 1/2 spacer, which put the Timbrens in ideal position in regard to the axle and loading.


I placed these on my farm truck and they absolutely did the trick. I haul hay trailers and cattle trailers and the difference these made over the OEM bump stops is remarkable.


Works well. At first, I had too many spacers, and it caused a harsh ride. I removed 1" of rubber and got my good, no load ride back. When I hitch up my 5th wheel toy hauler, I get a sure, stable ride, without rear end sag and front end lift.


The timbrens help control sway plus providing load leveling with a heavy load.
I really like them/



Been working great, helps keep PU level when trailer is attached with out load levelers! For long haul I still use the load lever hitch though.


Had Timbren rear suspension system installed on my F250 Super Duty. I use with a 3horse heavier blt trailer with 8ft short wall. I can't believe how much more stable the truck feels with this system. Love it and would most certainly recommend this system be added to their truck. I wish I knew years ago to add this system to my truck.


Did exactly what I wanted it too. It did require trimming and then sanding to match the top piece. It was a breeze and not too difficult.


Product works great! Installed these on a 2018 Ford F150 that has a leveling kit. I didn't want the truck to sit below level in the rear when towing my trailer. I tried the Timben without these initially, and then purchased these to maintain the ride height I was looking for. Well worth the money.


I have had these on many of my trucks, great product, better than air bags for me. I put these on a 2013 F-150 that pulls a 5000 pound boat. Easy installation and nice ride. Keeps my headlights aimed properly, no sag. Highly recommend.


Perfect fit and dialed in the clearance just the way I wanted it. I preferred to have my Timbrens on the closer side of what they suggested. I do wish they came with a longer bolt though for convenience sake. Fortunately, on the 2020 Silverado 1500's I didn't need the locknut at all, the hole is threaded. A little red lock tight for a little added security and I was done. They are holding great.


The spacers are great. I had previously installed the TORTUN4 Timbrens, but with a 6" lift the truck still sat too low in the rear when loaded. The spacers allowed the timbrens to come into affect much sooner and prevent rear end sag. Didn't know spacers were an option until I found them on etrailer. Thanks for an awesome website!


Just what I needed to reduce the gap between my Timbren helper springs and the bump stops.


Love my Timbrens and been using them for years. These 1/2 spacers are handy to help dial in perfect ride height.


Well made part. I actually need these instead of the ones that came with the Timbren kit, (TRF150D)



Moved from WA to central UT, made numerous trips pulling an 18 car hauler. The Timbrens kept everything level and firm. Love those things!


The guys at e-trailer and Timbren are great. Needed 1/2” spacers for my Tundra for my timbren overloads and they had them to me in 2 days. They fit and work great. Exactly what I needed. Thanks.


I put these on a 2007 Tundra and this past summer it pulled work& play toy hauler from Pa. To Yellowstone and back with no issues. The truck handled the weight great.


Works as described great service


Etrailer has nothing but great products and this was no exception exactly what I needed


Needed product quickly and dependably to complete a customers truck in a timely fashion. E trailer came through as promised w the correct product and delivered on time.

  • Does Timbren 1/2" Spacer Come with Longer Mounting Hardware
    The Timbren 1/2" Spacer # TA25722-90P00 comes in a quantity of 1 and only includes the spacer. If you require longer hardware then you'll need to visit your local hardware or home improvement store for that, which is actually the same thing we do when we install the spacers that don't already come with a suspension kit.

  • Is the 1/2" Spacer # TA25722-90P00 Compatible with the Timbren # TNRTTN on a 2017 Nissan Titan
    Yes, the Timbren 1/2" Spacer # TA25722-90P00 is compatible with the Timbren Rear Suspension Enhancement System # TNRTTN for your 2017 Nissan Titan. Please note that per the linked instructions for the suspension kit Timbren says that there should be a 1/2" - 1-1/2" gap between the rubber spring and contact point when there is no load in the vehicle. If you installed this kit and you have 1/2" of space then you actually won't need the spacer.

  • What Spacers are Available To Accommodate a 6" Lift on My 1995 Ford F-250
    Depending on the size of the bolt on your 1995 Ford F-250, we have a couple of options for spacers. Timbren does recommend 1/2" to 1 1/2" clearance between your Timbren and the contact point when the truck isn't under a load. The spacer is a solution if there is more than that clearance. If your bolt is a 1/2" bolt you will need the Timbren 1" Spacer For Raised Frame Vehicles - 1/2" bushing # TA25723-90AD00 or the Timbren 1/2" Spacer For Raised Frame Vehicles - 1/2" bushing # TA25722-90F00.

  • Recommended Spacer For 2007 Toyota Tundra With Timbren Suspension Enhancement System
    Per the installation instructions for Timbren Suspension, part # TTORTUN4, you should have between 1/2 to 1-1/2 inches of clearance between the rubber spring and the contact point when empty. It sounds like you are at the upper part of that. I recommend using a 1/2 inch spacer like part # TA25722-90P00 since you said you are very close to 1/2 inch when your fifth wheel is loaded. This would eliminate the gap you have with the trailer and still not affect the empty ride.

  • Is a 2" Gap Too Much After Installing Timbren Rear Suspension Enhancement System
    The ideal gap between the bottom of the jounce bumper and top of the contact point is about 1/2"-1" but you can go more if you don't want them to engage as soon or as often. Therefore, in lifted applications you'll need to use spacer to get the gap down to where you want it or the recommended 1/2"-1". This can be done using the Timbren Spacers part # A25723-90AH00 for 1" and or part # TA25722-90P00 for 1/2". The spacers can be stacked and as you noted you'd need a longer bolt which can...

  • Recommended Spacers For Timbren Front Suspension System for Leveling Kit on 2011 Silverado 1500
    For as many inches or half inches you add to the front of your 2011 Silverado 1500, I recommend using the appropriate spacers since you will be using a snowplow. I recommend the Timbren 1" Spacer For Raised Frame Vehicles # A25723-90AH00 or the 1/2" Spacer for Raised Frame Vehicles # TA25722-90P00. This will require longer hardware that will need to be obtained locally.

  • Are the Timbren 1" Spacers For Raised Frame Vehicles Sold In Pairs
    The Timbren 1" Spacer For Raised Frame Vehicles part # A25723-90AH00 are sold individually, you'll simply need to order one for each side or multiples depending on the lift. They are also offered in a 1/2" version as part # TA25722-90P00. You'll want the space between the spring and strike plate/axle to be about 1/2"-1-1/2".

  • Does Truck with 1-1/2 inch Lift Require Spacers When Using Timbren Suspension Kit
    With Timbrens you want to use a spacer to match as close to the amount of lift you have on the truck if the lift raised the frame of your truck away from the axle of the truck. Since you have a 1.5 inch lift you'd want the 1/2 inch spacer part # TA25722-90P00 plus the 1 inch spacer # A25723-90AH00 and you'd be set. Otherwise the Timbren won't be effective since it would require too much suspension movement for it to "activate".

  • Recommended Timbren Rear Suspension Enhancement for 2015 Jeep Wrangler Unlimited with 4
    We have spacers that you can add to accommodate a 4" lift on your 2015 Jeep Wrangler Unlimited, but there are no Timbren kits available that come preset for a 4" lift. If your Wrangler Unlimited is a 4WD then I recommend going with the Timbren Rear Suspension Enhancement System # TJRJK. If you have a 2WD then you will want the part # TABSJRJK instead. You can accommodate your lift by choosing a combination of the following spacers for raised frame vehicles: 3/8" Bushing 1/2" Spacer -...

  • Will Timbren Rear Suspension Enhancement System Fit 2008 Ford F-250 With 8 Inch Lift
    The Timbren Rear Suspension Enhancement System # TFR250SDF will fit your 2008 Ford F-250 but you may need quite a few spacers. You will need to measure from the frame to the axle where the Timbren would install to find the correct spacers. Timbren recommends 1/2" to 1" of clearance between the axle and the Aeon rubber spring. The height of this kit with the included spacer is 7-3/4" so you will need to subtract 8-1/4"-8-3/4" from your measurement which will tell you how many spacers you...

  • How Much Distance is Ideal between Vehicle Frame and Timbren Spring
    Timbren likes to recommend 1 inch between the axle and the Timbren when the truck is unloaded. We have found that this works the best. This allows the suspension to feel when the vehicle is unloaded and still gives you support when needed when towing. Since you have 1-1/2 inches currently you'd want to use the 1/2 inch spacer part # TA25722-90P00 to give you the ideal support/ride quality. Then for a the front axle you'd want the part # TGMFK25D which is confirmed as a fit as well.

  • Is Longer Bolt Required When Installing Timbren Spacer Kit on a 2013 Chevy Silverado
    When we have installed the spacers like the part # TA25722-90P00 with a Timbren like part # TGMRCK25D on a lifted truck we had to go to a local hardware store to track down a longer nut and bolt. Check out the install video that shows a similar install with lift kit spacers.

  • How to Help a 2018 GMC Sierra 1500 with Rear End Sag
    In order to help keep the rear end of your 2018 GMC Sierra 1500 from sagging while towing or hauling your four wheeler I recommend using the SumoSprings Solo Custom Helper Springs part # SSR-209-40. This spring will replace the factory jounce spring that you have on your truck and provide you with a cushion between the frame and rear axle that will help to alleviate some of the rear end sag you have while towing or hauling. The best option about this system is that it will not affect ride...

  • Spacers Needed To Add To Timbren Jounce Springs On a Lifted 2018 Ford F-250 Super Duty
    The Timbren Suspension Enhancement System # TFR250SDJ is designed to fit the stock height suspension on your 2018 Ford F-250. As you added a lift you will need to use 1" # TA25723-90AD00 or 1/2" # TA25722-90P00 Spacers to compensate for the amount of rear lift your lift added. You will need to source the M10-1.5 Grade 8.8 bolt locally that is the correct length depending on the amount of spacers you add.

    The correct spacer you'll need for the Timbren Rear Suspension Enhancement System part # TDR1500DQ on your 2011 Ram 1500 4x4 is the Timbren 1/2" Spacer part # TA25722-90P00 and or Timbren 1" Spacer part # A25723-90AH00.

Unfortunately, we do not have any airbag kits compatible on the front of your Jeep at this time. As long as you have the 4 wheel drive model then the above kit will work for you. If you have a 2 wheel drive model then unfortunately we really don't have anything that is going to work well. If you are referring to a body lift...

  • Installing Timbren Rear Suspension Springs on a 2021 Nissan Titan With Rough Country Lift

You can use the Timbren 1" Spacer # A25723-90AH00 to space out the Timbren for the Rough Country lift since they use lift blocks to gain your rear lift and are not using new leaf springs with different characteristics. We also have the Timbren 1/2" Spacer # TA25722-90P00 that can fine tune the height if needed.

    The Timbren Spacers, like the 1" # A25723-90AH00 or 1/2" # TA25722-90P00, are designed to be used with a Timbren suspension enhancement system so you will not want to use them with your factory bumpstops. I spoke with my contact at Timbren about using the Timbren Active Off-Road Bumpstops # TABSTOF with the 2-1/4" lift on your 2015 Toyota Tundra and my contact said that no spacers will be needed when installing these. The Off-Road Bumpstops are rated for 1,800 lbs, but keep in mind that...

    The total height of the Timbren Active Off-Road Bumpstops part # TABSOSR which are a fit for a 2011 Nissan Frontier is 4-5/8". If you want to add spacers you'll use the Timbren Spacer part # TA25722-90P00 and or part # A25723-90AH00. In regards to fitment, you can add spacers so there is no space between the contact point and bumper but this would not lift the truck and it could also result in a stiff ride.

  • How Close to Vehicle Frame Should Timbren Springs Sit Once Installd
    Timbren likes to recommend 1 inch between the axle and the Timbren when the truck is unloaded. We have found that this works the best. For a 1/2 inch spacer you would need the part # TA25722-90P00 and then for a 1 inch spacer part # A25723-90AH00. One of each of these will work great to get your Timbren setup right where it needs to be.

  • Installing Timbren Active Off-Road Bumpstops on 2016 Toyota 4Runner with 1-1/2 Inch Lift
    The Timbren Active Off-Road Bumpstops # TABSTORSEQ referenced in your question are confirmed to fit your 2016 Toyota 4Runner. As you mentioned, you should have 1/2 inch to 1-1/2 inch gap between the rubber spring and contact point when the vehicle is empty. The closer to around 1 inch, the better. In order to maintain that gap with the 1-1/2 inch lift you have on your 4Runner, you can simply add a Timbren Spacer like the 1/2 inch # TA25722-90P00 or the 1 inch # A25723-90AH00 to close...
