Review on 🔧 ACDelco 504 535 Specialty Shock Absorber: Premium Performance for Ultimate Dampening by Khiam Burton

Fits my 2007 Chevy Colorado 2.9L 4cyl 2WD CrewCab 5 foot bed and front coil spring. Easy installation. Two screws at the top and 1 screw at the bottom on each side. The truck did not have to be jacked up. Bought this primarily to flatten the rear end from GM sag. Sits nice and flat, maybe a little higher in the back, at 100psi with no load but with duvet on. The trick is to find a high pressure pump that can reach higher PSI levels to balance the towing capacity.
