4 Leaf of Replacement for SW4B Trailer Leaf Spring, 3500lb Tandem Trailer Axle Suspension Kit with 1750lb Capacity Double Eyes Leaf Springs, 2*U-Bolt and Hanger Kit

Without question a no brainer to repair our trailer! One side of our trailer leaf springs had broken 3 out of 4 springs were busted! Could have been life threatening. So glad to solve the issue with the new leaf springs kit!!

Installed this set up on a customer's coach 2 weeks ago and found when he got a little over 600 miles on the suspension, he experienced U-bolt failure and catastrophic axle damage. Needless to say, his trip is snagged up but he almost lost his trailer. Could have been worse. I left a really bad review initially and I had to recant my review after talking with the seller. They reached out and listened to what had happened and want to refund me to help refund my customer for the work so our mutual customer is able to not be under so much financial strain to get his coach repaired on the road. The seller asked for pictures of the failure so they can evaluate to be able to make their products better. I'm really impressed and admire their position to really help in this situation. I would definitely do business again in the future! I look forward to getting better U-bolts 😊

Perfect replacement for my old worn out flattened 4 leaf suspension. Upgraded to a 5 leaf set. Zero issues with the product. Quality is very good!Update:Trailer is absolutely butter smooth on the highway! I would highly recommend this kit to anyone. Extremely pleased with the performance!

Easy to install. Seams to be good quality.

Swift shipping and item as described well packaged

I ordered this to fix a trailer that I have that isn’t close to town and I get halfway into replacing the leaf springs and there was no U bolts or mounting hardware for the u bolts in the box. I had to drive hours back into town and buy U bolts. Very frustrating.

These seem to be good quality, however there is something to be aware of if you plan to replace the included nylon bushings with high quality brass bushings. The standard brass bushings that are designed to fit the eye holes of all similar leaf springs have an ID of 9/16” and OD of 11/16”. However I measured the eye holes of these springs at 3/4” which did not allow a proper fit of my brass bushings. So, if you plan to utilize the included nylon bushings you will be good to go with these springs. However, if you are planning to use brass bushings with an OD of 11/16”, they will not work with these springs. I was unable to find brass bushings with an ID of 9/16 and an OD of 3/4.

Worked perfect for my boat trailer, I may be changing the bolts out for some nicer ones eventually but they worked great for my roadtrip and held up solidly
