Timbren Rear Suspension Enhancement System

by: Jesus07/15/2023

Works perfectly as expected. Took the extra bounce out of the rear-end when towing out 5th wheel.
It also keeps the tow vehicle level when fully loaded with 5er and all our gear.1624455

purchased for my 2022 Ram 2500 Limited 4X4. Once I got it in hand and did measurements it was obvious that with the weight I normally carry these would be engaged all the time and affect the ride so didn't get them installed. Also, on the Ram the right side was going to be a challenge without putting the truck on a lift.1548063

I want you to be able to use the Timbren springs. As long as there is a 0.5 inch to 1 and a half inch gap between the rubber spring and the contract point on the axle when the truck is unloaded then they will work correctly for you. It is normal for the springs to be in constant contact with the axle when loaded this is going to give you the smoothest ride. It is actually when the truck is unloaded with springs on that you may experience a rougher ride.

After a year of ownership and being able to tow a trailer over 20k miles I've really come to appreciate the simplicity of these progressive bump stops. I originally installed the bump stops that came with this kit but they were a little too harsh. After talking with Timbren directly they sent me a lighter compression ratio bump stop and they work fabulous. I use them on a 2021 Ram 2500 towing a 5th wheel with a tongue weight of around 2800#. My truck stays level and has a softer ride. Thanks!1685649

Spoke to a guy last time we were out camping with the same truck and he recommended Timbrens, so I installed them on my 2020 2500 RAM diesel. I did not use the 1" spacers, as we installed them with the camper (Hallmark popup) on the truck and the stops were already close to the axel. They've transformed the handling of the truck with the camper on it and I highly recommend them. Haven't driven it yet with the camper off, but fingers crossed.

Unfortunately, the package arrived on a Friday and the box was torn up and held together by rubber bands. No tape, just rubber bands (!) and the mounting hardware had disappeared along the way. I managed to call E-T before they closed but that wasn't going to get me the bolts before the weekend so I ended up going to OSH for some inferior hardware. Have since received the good stuff from E-T...1632310

I think I will be very happy with the ride when I tow our fifth wheel, it definitely needed the extra support especially on rough roads.I chose not to use the spacers because I like the softer ride when the truck is unloaded.1331866

I installed the Timbren Rear Suspension Enhancement System on my 2019 Ram 2500. It was a perfect fit and was a thirty minute install. It does exactly what it is designed to do, enhancing the ride and stability while towing my 43’ fifth wheel. And without the trailer my ride is not affected at all. I highly recommend adding these if you tow or haul heavy loads. I have three friends that have purchased these since mine were installed.1585037

Took longer to read the instructions and clean then grease off my arm (which I got from rubbing against the lower shock mount), than it did to install. The drivers side is SIMPLE, the passengers side is a bit more tricky, because on the 2014 RAM 2500, the right side mount is directly ahead of the upper suspension torsion bar mount, so it's tough to get a wrench in there. I have a 15mm curved thin wrench, which worked perfectly! I've attached photos of both sides, so that you can see what I mean.141108

Did exactly what I wanted...kept the truck level with my 5th wheel camper hooked up. Originally truck was not that bad but at night I was getting high beamed. Made just enough of a difference to eliminate that.1605947

Excellent product! Went on in less than 10 minutes with a 15/16" wrench. Leveled the truck out under load and significantly reduced roll. Awesome bang for the buck. And etrailer service was spot on, as usual.378049

I still think these are an excellent alternative to bags and very cost effective. My only complaint is that on my 15 Ram 2500 I have to switch out the extra spacers when I’m not towing heavy. The axle and Timbren spacers make contact when unloaded and causes a harsh ride. The good news is that the extra spacers go in and out in minutes I don’t tow heavy very often. With the spacers in I am able to pull a 43’ toy hauler with little roll and excess bounce, an the truck sits fairly level

I love this option for load leveling and keeping our camper from swaying. This is the second truck I've installed these on. Super easy to install. Keeps the factory smooth ride unless you hit a big bump. When loaded, the ride is great. They take the bounciness out of the load. The only negative would be they're a little over priced for a chunk of rubber but otherwise I highly recommend these. 822741

Ok, the drivers side was very easy to install. Maybe 15 minutes. The passengers side was another story, the rear bolt was very difficult to get at and took a great deal of time and creativity to get the bolt tight do to no room to turn the wench.
That being said it did improved the ride a great deal with no load, I drive country roads that are very rough , it completely stoped the wheel hop and provide a much better ride.
I would recommend installing these I’m glad I did! I would give this 5 stars if it were not for the passenger installation.1330587

Very easy to install and perform very well. Makes the truck handle well under heavy loads.1681175

Got them both. Installed. One issue with the right side. The bracket fit, but to tighten the rear bolt was a challenge to tighten it. I had less than 2in. to get it tight. So I had an old wrench that I just cut to the size I needed. All good.1665190

Haven’t pulled the Fifth wheel yet, we’ll have to see how that goes. Appreciate your interest in getting our feedback. Installation was no problem.1660478

I have only given 4 stars because I have yet to drive any distance with them. Install was easy, I used a floor Jack to let the suspension drop. Did passenger side first as in other reviews it was deemed to be harder to change. For the passenger side I mounted the tambren after mounting the bracket. The driver side I put the tambren on and the mounted.1594814

The item arrived and installed in under 40 min total. The installation was much easier than expected. Chose not to install the spacers per the suggested directions allowing a half inch to three quarter inch between the joist spring and rear axel. Was able to install without lifting the truck, doing both sides from the wheel well by simply reaching over and around the tires.1594801

I've had these for a year now. They've made a huge difference when towing my 5th Wheel Travel Trailer with my RAM 2500 - the pin weight is less than 1500lbs, and total weight is about 12000lbs, however, in strong winds there was a fair bit of sway. This product took the sway out completely. I'd recommend it to anyone with the same problem, especially as a first step before spending excessively on other more expensive solutions that may not be necessary.1342602

This is the second set I ordered. They were a great product for my f150 when towing a trailer. When purchased for my ram 2500, all they did was make the ride unbearable when loaded with a trailer! I thought about going to a hospital for kidney damage! Luckily I kept the original bump stops and tools in my truck as I swapped them out on the side of the road.

Perfect for a 1/2 ton truck, bad for a 25001515997

etrailer had videos to explain exactly how to install the Timbern stabilizers and this made the install fast and easy. I am quite pleased.1258564

Great I have no sag when hooked up to the 5th wheel and the ride is comparable to air bsgs.

by: Jim12/01/2022

I installed these on a '19 Ram 2500 4x4 to help with the dip and sway associated with carrying a Palomino slide in truck camper. Even with the Timbrens the truck was not a good carrier of this type of camper. Before you wonder if I had overloaded the truck I'll let you know that the camper (wet) was about 2200lbs but the truck was rated for 3100lbs. Anyway decided not to keep the truck and traded it for a F350 Chassis Cab 4x4 SRW and don't have the problems any longer.1476919

Easy installation except the passenger side is a little harder.1614280

I bought these for a 2020 Ram 2500 because they had great reviews here and at a lot of other places around the internet. They do not fit correctly. On the passenger side, they are almost touching the frame with no load in the bed or on the hitch. The ride is absolutely terrible, very rough and painful. The ONLY time it's tolerable is with my 3000 pound camper in the bed of the truck. I would have returned these, but I waited a few months to install them, so it was too late by the time I realized how bad they were for my application. If you have a truck that is always loaded with a lot of weight, this would be awesome. Otherwise, spend the extra money and get air bags. I will be installing air bags and throwing these in the trash.1320437

I am sorry to hear that you are not happy with the system. Before you replace them or throw them away, I will have the manufacturer reach out to you.

The installation on the drivers side went great. The passengers side I had to cut a 5/8 wrench in half to tighten one on the bolts.There was a bracket or brace in the way. My 2016 Ram 2500 Tradesman sits level now when I hook my 9000 lb. Tiny House on Wheels to it. SandD Stained Glass.293370

Super easy to install and works very well when hauling heavy loads, less sag on rear of truck and more stability when turning, would highly recommend these for an alternative to airbags, as always great working with the guys from etrailer.com, have ordered several things thru them and am never disappointed, quick to ship and very helpful, customer service at its best.562953

They do exactly what they are supposed to do. Air bags way to much trouble with leaks and all.1526995
