Review on ACDelco 525 21 Specialty Heavy Absorber: Superior Performance for Maximum Efficiency by James Roper

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 eliminated, so I'm very satisfied. These in combination with my new A-pillars (procomp) have completely changed the driving characteristics of my truck. Solid black finish (compared to Procomp posts on the front) with no scratches or damage. on arrival UPDATE NOVEMBER Nine months later they started making noise, creaking and rumbling. The shock itself is loose at the lower mounting point, although the shock mounting bolt is secured. According to acdelco they are guaranteed for 12 months, but Revain cannot replace them. They can only be returned. Should have bought from the store so I had a spare instead of going through this 2003 Dodge Ram 1500 4.7.
