## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product.
*by T***P on August 25, 2024*

I had lowered my gmc 8” in the rear. I was able to use my stock shocks with this.

### ⭐⭐⭐⭐ 2006 Chevy Silverado, 4” Rear Lowering Kit
*by C***A on August 1, 2025*

Sturdy Build, Good Components, Easy To Install, Self Explanatory, about 5 minutes is all you need. Looks Great,

### ⭐ Waste of money, they don’t work
*by A***R on January 26, 2026*

These make absolutely 0 sense, they don’t extend the shock at all if you measure the shock length with these and without these “extenders” it’s the exact same length. Don’t waste your money like I did.
