Unbalanced suspension can make your trailer lean or bounce unevenly. This hanger kit includes a pair of 13-1/8" long straight equalizers designed to level tandem axles so the load stays balanced front to back. The equalizers pivot smoothly on 7/8" diameter center holes with wet bolts for consistent travel, helping the suspension move together over bumps instead of fighting each other.
Light hangers can twist or stretch under a full load. The 4-1/2" tall front hangers in this kit are made from 1/4" thick steel, giving you the same strength found on commercial-grade setups. Combined with 3-1/2" tall center hangers and 5-1/4" tall rear hangers, they form a tough mounting foundation that stays true mile after mile on trailers using tandem 3,500-lb to 8,000-lb axles.
Getting the right clearance between the frame and the axles keeps your trailer tracking level and prevents bottoming out. This kit sets up about 5" of clearance, depending on axle size, so your suspension cycles freely while keeping the trailer’s stance balanced. The hanger heights and equalizer dimensions are matched to maintain correct geometry for smooth, predictable handling.
Instead of hunting for individual parts, everything needed to mount the 2" wide slipper springs to the frame is here, from bolts to locknuts. You get spring keeper bolts, shackle bolts, and 7/8" wet equalizer bolts to tie the suspension together securely. Components for mounting the axle to the springs are sold separately, but the core frame-side hardware arrives ready to go for a clean, complete install.

The parts I received, we're exactly the parts I needed. Great quality, and etrailers prices beat, all other parts that I found on the internet. I will be buying from them again.
Thank for the great parts and great service.
It is hard to find such great quality and great service ANYWHERE these days, HOWEVER etrailer still has what it takes. The people always make a difference when you need help. A+
They have great Tech support online chat, email, by phone and even great tech articles.
We ordered this kit for a customer in order to repair their bent, twisted and torn suspension. It was exactly the original replacement parts necessary to return the trailer to its original condition. The customer is happy and satisfied we were able to solve his issues quickly and efficiently with this kit.
the correct parts for a trailer that's almost thirty years old. wow thanks guys and I will gladly pass on my satisfaction to others
Added a third 7000 lb axle to our 14000 lb trailer. Easy to install, fit perfectly. Handles the weight better.
I purchased the 7 leaf sliper spring to replace my old ones. etrailer had all the parts needed to rebuild my trailer. The parts fit perfectly. The people there are very knowledgeable about the trailer parts and what is needed and what will fit when replacing old worn parts. I would stronly recomend etrailer for any of your trailer needs.
Very prompt service and delivery.
We purchased this kit to rebuild an older trailer with worn parts. We received the kit promptly, however, the package was compromised and bolts were missing when it arrived. A quick call and the problem was resolved immediately. Two days later all new bolts appeared on our doorstep. Great company that cares about taking care of its customers. We truly appreciated that and will surely order again very soon as we have several trailers in our fleet.
This kit (a dual kit) changed my view of Dexter as a quality-first manufacturer. etrailer simply sells it, they don't make it, so they aren't to blame.
This kit is made specifically for mounting Dexter's General Duty 9,000 lb axles in tandem and is different from kits made for 3500 to 8000 lb axles. It provides extra axle tube to frame clearance to accommodate the 4" axle tubes used on their 9k and 10k GD axles. It uses beefy 7/8" equalizer pivot bolts and 5/8" spring eye bolts. So far, so good. Until you pay over $350 for it and receive a suspension kit with absolutely ZERO lubrication provisions! Seriously, Dexter?!! The bolts provided are all just grade 5 hardware store plain jane dry bolts. Not even grade 8.
Dexter sells 7/8" greaseable "wet bolts" and even their lighter-duty hanger kits include greaseable wet bolts. But even if I paid etrailer the nearly $XX apiece they want for them (they're half that price elsewhere), there is literally no way of putting a square-shouldered carriage-style bolt, which they are, in the round roles this hanger kit was manufactured with without modification. As for the 5/8" spring eye bolts, only a great deal of internet searching will find any wet bolts the right diameter, and they'll be the wrong length. Those 4 bolts are about $20 each plus shipping.
So, by the time I pay a machine shop to square the equalizer bracket holes on and buy all the wet bolts, or have them made, JUST so I can lubricate this expensive hanger kit in hopes of it lasting more than a very short time on a trailer that often grosses 20k, I'm going to have over $500 invested in it, not counting all the extra wasted down-time. This kit was supposed to solve my trailer suspension problems, not create more. FAIL!!
If I were to rate this product I would want to say it was better than excellent.
Very impressed with your products. definitely beyond my expectation.
If fact I ordered brakes for the trailer the very day I received slipper springs kit.
Everything was equal to or better than original. However I was not impressed with the packaging. My parts showed hanging out of the boxes. Luckily everything was there.
Everything was great
Minor modifications needed to fit on ancient trailer, but products were a good investment in the restoration on an old horse trailer.
Springs and hangers fit as they should. Easy install and everything is working as designed. Thanks for the quality parts at affordable prices.
Good product. Doing a great job for me so far. I used the kit to upgrade our toy-hauler from 1.75” to 2” leaf springs.
fit perfectly
