The Belltech Trail Performance rear shock for 2019–2021 GM 1500 4WD trucks is tuned for lifted applications with a 6–8 in. lift range. Engineers tuned low-speed compression to control pitch, roll, dive, and squat, while progressive rebound complements large off-road tires. Construction includes metal dust boots, hardened chrome piston rods, low-friction seals, a wide 51mm body for increased oil volume, and OEM-style bushings for durability.
