Fits select 1973-1991 Chevrolet Blazer, C10, and Suburban, and GMC Jimmy, C15, and R1500 models.The Belltech Nitro Drop 2 shock absorber (MPN 8511) is engineered specifically for lowered trucks and SUVs, offering a refined balance of daily-driver comfort and enhanced suspension performance. By increasing low-speed compression and optimizing rebound forces, Belltech engineers have created a damper that provides a firm road feel and improved grip without sacrificing factory-style ride quality. This shock features an application-specific shortened body to maintain proper travel with Belltech lowering kits. Large 55mm body diameter and twin-tube design for increased oil volume and superior heat dissipation. 30mm piston and rebound valve assembly reduces oil aeration for consistent damping performance. Low-friction sealing and guide system provides rapid reaction to small suspension movements. Steel dust cover adds heavy-duty protection for the piston rod and sealing system against UV and chemicals. High-durometer vulcanized rubber bushings significantly reduce noise, vibration, and harshness (NVH).
