One bad shock can be but 2 bad shocks is unacceptable

Removed shocks from box and noticed they didn't have ties to keep them closed but they were closed the shocks didn't stretch by itself. Very disappointed truck on my lift and no shocks

Pros
  • Absolute Legend
Cons
  • Long shipping time

Revainrating 5 out of 5

Not Very HD - Excessive Rebound

The shocks appear to be quality for the price, but they have excessive rebound or rebound when going over bumps - especially the rear on our 2009 GM 3500HD - looks like they are Shock absorber worn. Wouldn't buy again - will probably get a stiffer shock like a Bilstein.

Pros
  • New
Cons
  • Discarded

without support and did not fall apart as it should.

Every complaint here is one received. These are not spring shock absorbers, they are liquid. You can take them out and put them back in by hand, that's the way it's supposed to be. These shock absorbers do not compress for transport. They are powered by a fluid with a damper. No spring and no holder. They work fine.

Pros
  • Consistent test results
Cons
  • Upgradable

Nine months later they are roasted. No exchange, only return!

These are liquid dampers of excellent quality! ! You are not blocked, you are just WEAK. I replaced both rear shocks in less than twenty minutes. 20 MINUTES. Easy assembly and disassembly with two screws. The tools used were a 20mil socket and a small swivel extension (to access the top mount). There is no need to remove the spare wheel or wheel well protector, it's that simple. After installation, I immediately noticed hardness in the back of the truck. . Almost all body roll in corners…

Pros
  • Delivery was very fast
Cons
  • Not everything fits
