Overall Assessment

Customers highly recommend this product for its solid quality and fair price, expressing satisfaction in its functionality, given it successfully lowers vehicles to desired height. It's praised for being a comprehensive kit and offering great practicality for different car models, like the '35 Chevy Coupe and '89 s10. The lowering kits are described as looking nice and fitting well. However, a recurring issue mentioned is the short length of the U-bolts included in the kit, suggesting that longer ones would benefit the assembly process. Despite this, the kit is perceived to provide good overall value.

u-bolts too short

The product came very quickly in the mail, and I was quite happy. However, the u-bolts provided with the kit were just about an inch short in my opinion. I had to remove my overload leaf to make it fit on my 1953 ford.
