## Customer Reviews

### ⭐⭐⭐⭐⭐ Safety
*by T***P on March 21, 2025*

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!!

### ⭐⭐⭐⭐⭐ Be careful, U-bolt failure experienced right after install
*by D***Y on July 15, 2024*

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 😊

### ⭐⭐⭐⭐⭐ Excellent replacement! UPDATED!!!
*by T***  on December 18, 2024*

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!
