## Customer Reviews

### ⭐⭐⭐⭐⭐ Belltech shock extendenders
*by J***. on 22 September 2025*

Fit perfect on the truck with no issues, work as they should. Super happy with purchase.

### ⭐⭐⭐⭐⭐ What I've come to expect , quality products that work!
*by R***D on 24 May 2020*

Exactly as advertised, excellent well designed products!

### ⭐⭐⭐⭐⭐ Corrects shock angle on lowered trucks.
*by A***E on 11 August 2017*

Worked great and corrected my rear shock angle after lowering my 2001 Chevy truck. I recommend these if you've lowered your vehicle. When you lower the truck, it changes the angle at which the shock works at. It's not a good angle and can affect the ride. These correct that angle. Not so much of a length extension though, but that's fine.
