Rough pavement and uneven loads can make a trailer buck or sway. The Suspension Kit for Tandem-Axle Trailers keeps things steady with equalizers that measure 5-3/4" from bolt center to bolt center and 2" tall. They let both axles move together, transferring load and impact smoothly so your trailer tracks level and the ride stays consistent mile after mile.
Suspension parts take a pounding, so weak hardware isn’t an option. This kit includes fourteen 3" longx9/16" diameter Grade 5 bolts with tapered locknuts that resist working loose from vibration. The secure fit keeps the connection between springs, hangers, and equalizers tight without binding, so the suspension can move freely under load.
Getting the alignment right makes all the difference in ride quality and tire wear. This setup is built for tandem-axle trailers with 33" axle spacing and 1-3/4" wide double-eye leaf springs. The 2-1/4" shackle straps match the geometry of the equalizer to keep the suspension cycling smoothly through its travel.
When factory components wear out, this kit brings your suspension back to spec. It includes two equalizers, eight shackle straps, fourteen bolts, and locknuts. Hangers and springs are sold separately so you can match them to your trailer’s frame and axle rating. The result is a balanced, dependable suspension that rides right and stays quiet on the road.

Exactly what I needed to repair my older trailer and make it safe again. Fit exactly the way they should. Fast shipping.
The parts I ordered were exact replacem ents.
Fit up perfectly. Easy to swap out. My axles balanced perfectly after the swap
This is exactly what you need to freshen up your trailer’s suspension. I’ve put roughly 10k miles on mine since I purchased a year ago. You would be surprised how shot your original hardware can be. Should be able to get another 10k before I need to replace again.
It fit perfect
I RECIEVED EXACTLY WHAT I ORDERED IN A TIMELY MANNER
Not impressed! Shipped and arrived in a reasonable time, everything appears to still be in the box, but there’s no excuse for this. I think some stronger boxes are needed for heavier items, and UPS could show a little more respect for people’s thing, instead of throwing around almost $500.00 worth of items like it’s junk.. as far as the items, everything looks decent, will install when temperatures are out of the sub zeros.
Converted my 30 ft home built trailer to carry my 25 ft sailboat with 3 1/2 ft keel. I needed new springs to carry her weight Your parts arrived on time. So far all is going well on the upgrade. Thanks for the positive information and can do attitude of your company.
Haven’t used these yet, but nice to know I have them when needed.
After all of the bad weather I was able to finish installing my new suspension system on my 1992 Lance Fifth Wheel. The task was much easier than I had anticipated. The instructional video you provide access to were a big help. Other than having to grind off a nut or two I had no difficulties (See attached photos). The 'list' that had developed on the fifth wheel is now resolved, and towing has already proven to be better.
Great kit, the fit was perfect. The staff at trailer was incredible in making sure I had the right parts. Its definitely important to buy new fasteners when replacing springs (I had an OEM spring in a travel trailer snap underway). The shackles show surface rust after 3 weeks of camping in wet weather (I live in the desert) which was surprising.
Works great fits great. Product seems to be good. It’s on a flat trailer that I don’t use a lot. But the products seem really good.
Fast and easy and right what i need to get my trailer fixed
Had no issues installing the parts. Great fit on all parts. However, I suggest to purchase the “up grade” wet bolts and brass bushings and avoid the factory nylon bushings that come with the leaf spring kit.
Full disclosure: we boat in brackish water in Florida, but I always hose the trailer down afterward.
Springs work as they should and installation was straightforward. However, I’m not sure how long they’ll last. After only 5 or 6 launches/ retrievals last year, this is what they look like now. The springs and equalizer must’ve been spray-painted at the factory, not powder-coated. I believe made in China. I even soaked the bolts and links in motor oil before installing to stave-off corrosion. I just hope we don’t have a failure on the road any time soon because of this accelerated corrosion!
I bought this to prepare my trailer for a 3000 mile trip. Everything went together perfectly and worked flawlessly for the entire trip.
Fast shipping and item description was right on the money. 3rd time ordering from etrailer with zero issues
I had excellent help in ordering the correct components. It was a tricky order. Now the suspension on the boat trailer is complete and it's like new again!
This kit was exactly what I needed for my old worn out trailer. Arrived on time with all the pieces.
Perfect exactly what I needed and received it quickly. Quality parts.
Great service and parts
The bushings in my leaf spring equalizers were shot.
I was able to use your rebuild kit, and it made a major improvement.
This product is all oem quality just like the Dexter axle and spring manufacture bolts and everything else looks the same and lines up in the holes and fist well.
Fits just as OEM. A lot of reviewers complain of the bolts being shaped improperly however that’s not the case. The supply you with the correct crushed nuts. These nuts have one normal side and one side that has been squeezed by a press. They act as a lock nut without the poly inside. My only complaint would be that they supply the 10 bolts and nuts for the shackles but only give you two remaining bolts for the spring ends instead of the four it takes to replace those as well.
Good product. I Have a tendency to overthink, overbuild and over engineer everything about my camper so I did pull the plastic bushings and installed a nice set of bronze bushings. You will need a press or at least a vice to do this. Its also a good time to service the brakes and re grease the bearings.
