The Fabtech Dirt Logic 2.25 reservoir shock for 2011 GM 2500/3500 rear applications replaces OE damping with a larger-diameter, corrosion-resistant unit tuned for heavier loads and lifted vehicles. It uses 304 stainless steel bodies and aluminum reservoirs to reduce heat soak and fade, NitroSteel piston rods for durability, and urethane bushings to lower noise transmission. Dirt Logic shocks are rebuildable and available with custom valving.
