This is a very good kit. Over the standard kit, the big differences are: 1) bronze bushings instead of plastic, 2) greaseable (zerk fittings) hollow bolts for both ends of springs, 3) zerk/grease fittings on all three load equalizer bushings, and 4) extra thick shackle straps (1/2” instead of 1/4”). The only unfortunate part is the kit costs 3-4 times what the standard kit costs. In my opinion, it is still very worth it. One part I didn’t like and didn’t have great luck with is the instructed method to install the greaseable bolts and the top equalizer bolts. Under the bolt heads is splined for about 1/4”. The splines MUST engage with the spring hangar hole to prevent the bolt from turning. If the bolts are allowed to turn in the hangar holes, the holes will quickly become oblong because the bolts will turn here instead of against the bushing as designed. This will quickly oblong/oval the hangar holes. The instructions say to use a piece of pipe over the grease fitting (to prevent damaging it) and to hammer the bolt in. This works marginally well, but I was not able to get any of the bolts fully seated with this method (by the way, a 3/8” pipe nipple 6-8” long from a local hardware store works perfectly for this). When hammering against the bolt heads, you’re really hammering against the spring hangar. It’s like hammering against a diving board (not very effective). After starting the bolts with the pipe and hammer method, I made a special tool. It is nothing more than a piece of 1/4” thick steel with a half circle/recess torched out (see pictures). I then tapped this in between either the spring end or the equalizer (depending on which bolt I was working on) and the hangar with the bolt in the half circle/recess. This spacer allowed me to use the bolt nut to draw the splines fully into their hole. All that said, I have a number of words of caution: 1. When using this special spacer tool, still DO NOT use an impact wrench to draw the bolt splines in! This will just spin the bolt and likely wreck the bolt and the hole. By hand only! 2. Furthermore, be careful how much torque you use to draw the splines in! It requires a bit more than the normal 50 ft-lb of torque when tightening the bolt, but definitely don’t use a 24” breaker bar. The bolts are 9/16” bolt, but the nut and thread are only 1/2-20 (fine thread). It would be very possible to use too much force and twist off/wreck the bolt. 3. To get my hangar holes back to their correct size (allowing the splines to engage), I welded up the edges of the holes, ground them flat, then redrilled to 9/16”. While this worked very well and is much easier and cheaper than installing new hangars, the weld metal is harder than the original hangar. This is likely why I had added trouble getting the bolt heads fully seated. Two final notes: 1. When removing the old bolts without damaging/enlarging the holes under the bolt heads (assuming they’re not oblong/oval like most of mine were), an air hammer works great for this. 2. The spring hangars should be slightly wider where the bolt passes through them. Mine had become slightly collapsed here. I just used a big adjustable wrench to splay the two sides of the hangar apart from each other again. When installed, the bolt should draw the sides of the hangar back together (it’s like a spring). I used a bolt to gauge how far to go – farther than the shoulder of the bolt, but not so far you can’t get a nut on. They shouldn’t be splayed a whole lot – maybe 1/8-1/4” maximum.

I bought these to replace an aged set of what looked to be OE hangers during a retrofit to raise the trailer. Three items that drove me to this set: wet bolts, included metal bushings, and the side plates are massive! They look to be well-built, and all hardware is included in the kit. I feel much better about the suspension integrity after adding these, knowing the load placed on them during tight maneuvers.

Over six thousand miles, and all is well. Ive greased them twice probably overkill and not one creak or pop from the springs. Thanks again, etrailer!

So much better than the original parts. Heavy duty shackles, brass bushings and it's all greasable! It'll last forever.

Got sent one bolt that did not have the grease zerk drill and tapped into it.

I will have our customer service team reach out to you.

I used this kit to upgrade the suspension on my travel trailer. The original suspension was a "dry bolt" system with plastic bushings. This system allows me to lube all parts of the suspension, plus the bronze bushings will last much longer. This upgrade also eliminated all of the annoying squeaks I was getting a slow speeds and while maneuvering. I highly recommend it.

- K71-359-00

The original 1997 std dexter suspension kit had a good run hauling firewood. This kit will definitely outlast the trailer it’s attached to and I’m sure if my trailer would have originally been equipped with these I wouldn’t have had to replace them. I will definitely buy again in the future if needed for another trailer.

- K71-359-00

The suspension kit with Hardware made it nice to install on my 2007 Weekend Warrior toy hauler. I recommend this when installing new leaf springs as it makes it much nicer then having to fight with all the old bolts.

- K71-359-00

Replaced axle bolts with greesable bolts. It took about 1/2 day to install. The next week went on a 5500 mile trip and never looked back. No squeaking. 1 of the original bushing were already worn through @ 8000 miles on the Travel Trailer.

I ordered the Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers. I was sent 2 equalizers with no grease fittings. I called back and tried to explain to the lady (who didn't have a clue) that I needed 2 equalizers with grease fitting or 2 wet bolts (with grease fittings). Today I received 1 zerk fitting in the mail. This is really frustrating!!

Thank you for taking the time to leave a review! Our customer service team should be reaching out to you in the near future.

I used this for the wet bolts, bushings, and shackles. Installation was easy.

I have 6 and 1/8 th equalizers . i used Dexter heavy duty supension kit K71-359-00 removed bushings from equalizers in kit . removed old plastic bushing from my equalizers drilled 13/64 hole in center of top hole taped hole with 1/4 by 28.for grease zert replaced brass bushings from equalizers in kit to my equalizers then put it all together. great kit

- K71-359-00

The kit was delivered as described, WITH THE EXCEPTION that the equalizers were shipped from Dexter without zerc fittings on the center pivots.. However, etrailer followed through, providing wet bolts in a subsequent shipment.. Dexter is investigating.. As my trip could not be delayed, I lubricated the dry center bolt originally provided with moly grease. After only 3000 miles, significant bronze deposits had transferred to the bolt, IMO, indicating the absolute need for a wet pivot with the bronze bearings.. Hats off to etrailer support for following through to correct the problem.. thank you

- K71-359-00

Great product. Some history first. In 2014 I purchased a Keystone Outback and drove from Maine to Alaska and back. Upon returning I had the suspension (original equipment) inspected. The shackles were stretched out nearly torn apart. The equalizers were distorted and most of the nylon bushings were non existent. A catastrophic failure was only a few miles down the road. I had all parts replaced with OEM equipment and four years later of casual use experienced similar failures. I replaced (myself) all parts with this heavy duty suspension kit. Took me about 6 hours to complete. We then again drove from Maine to Alaska and back. This time inspection showed absolutely no sign of any damage. The entire suspension was still tight and in like new condition. Certainly worth the investment.

The past year we have slowed down a bit travel wise but the suspension system is tight and working like new.

Product is way better and stronger than stock

- K71-359-00

This product was installed along with Road Armor equalizer. The trailer’s ride improved significantly. etrailer’s work was great

- K71-359-00

Quality seemed to be good. I thought I ordered the kit for the 35" axle spacing but got the kit for the 33" spacing. Had most of the parts already installed by the time I realized the mistake. So, it cost me an addition $124.34 for the correct equalizer. I know mistake for not checking all the parts before starting the install.

- K71-359-00

Excellent product. I did strip a nut trying to draw one of the pins in instead of pounding it in like the instructions said. Otherwise everything went together without a hitch. Used a 5/8 bolt to remove the nylon bushings. Threaded it into the bushing a little and then pounded them out I used a half inch carriage bolt with nuts and washers to install the bushings instead of pounding them in. Worked pretty slick. Looking forward to many trouble free miles

- K71-359-00

Product seems to be well made. I could not use the bushings on the older spring set I have on my utility trailer. Nice feature to be able to grease these pivot points. The shackles (hangers) are definitely heavy duty and should last a long time. Received the product in a timely manner and am very satisfied with the company and product. Gave a 4 rating because time in use will tell how the product preforms. Would have been nice to be able to select a different design on the equalizer bar for different applications.

This product is worth the money spent. Just keep it greased and these should last longer than you will.

I ordered my suspension upgrade kit on Wednesday and was shipped the same day. I'm expecting my order Friday. Stacy did a great job at taking my order and asking the right questions to a new customer. 5 stars

- K71-359-00

Much beefier shackle design with wet bolts and metal bushings to replace the cheap thin plastic that LCI provides with their shackles and pivot. Very pleased with the outcome.

- K71-359-00

I installed them this spring, here are a few pictures. I also installed all new bushings and greasable pins. It was a good thing I replaced these as the center bushing on my old equalizers were broken. The new equilizers are a couple inches taller than the old one, raise my trailer over an inch. This worked well as my new truck is higher than my old one.

Chris really stepped up to help us in a desperate situation! However, prior to Chris assisting, the warehouse couldn’t find an item it said was in stock, potentially delaying our order! Chis and Adam who got Chris involved were able to come up with a resolution which helped to save us while being on the road in St Augustine Florida!

- K71-359-00

Ordering was easy, as the website was orderly and easy to navigate. My order was shipped out on a timely manner and packaged quite well. Plus the fact that etrailer has available informational videos that you can download. I highly recommend etrailer for any trailering parts that you may need.

- K71-359-00

This is a good kit to replace worn bushings, bolts, and equalizers. Mine were worn badly and this will restore it to proper operation. My bushings were seized in and some needed to be cut with a hack saw to allow them to be removed. The curb side is done. Now on to the street side.

- K71-359-00

Replacing the cheap OEM brackets that were installed in the factory. These spring brackets should outlast the RV.
