Fits select 1999-2010 Cadillac, Chevrolet, GMC, and Hummer trucks and SUVs including Silverado/Sierra 1500, Tahoe/Yukon, Suburban, Avalanche, and H3/H3T.The Belltech Nitro Drop 2 shock absorber (MPN: 8521) is engineered to provide a refined ride for the truck and SUV market, specifically targeting daily drivers. By increasing low-speed compression and precision-tuning the rebound forces, Belltech engineers have created a damper that maintains factory-level comfort while significantly improving road feel and tire grip. The Nitro Drop 2 line features application-specific shortened bodies to ensure proper suspension travel when paired with lowering kits and components. Large 55mm body diameter and twin-tube design for increased oil volume and superior heat dissipation. 30mm piston and rebound valve system designed to eliminate oil deterioration for long-term durability. High-durometer vulcanized rubber bushings reduce noise, vibration, and harshness (NVH). Low-friction sealing and guide system creates a quick-reacting damper sensitive to minor road imperfections. Durable steel dust cover protects the piston rod and sealing system from UV exposure and road debris.
