Belltech Street Performance Shock Absorber 310400 for Select 1999-2010 GM and Hummer (45mm Body)

Fits select 1999-2010 Cadillac Escalade, Chevrolet Silverado/Tahoe/Suburban/Avalanche, GMC Sierra/Yukon, and Hummer H3/H3T models. This Belltech Street Performance shock absorber (MPN 310400) is engineered to provide premium ride quality and improved handling for lowered trucks and SUVs.

Specifically tuned to address the low-speed compression characteristics of modern sport trucks, this damper significantly reduces pitch, roll, brake dive, and acceleration squat. The progressive rebound tuning is optimized for vehicles running larger aftermarket wheels, maintaining a smooth, firm ride without the harshness often found in generic replacement shocks. The twin-tube design features a large 45mm body for increased oil volume, ensuring consistent performance and better heat dissipation during demanding driving conditions.

• 45mm body diameter with twin-tube design for increased oil capacity and heat management

• Low-friction sealing and guide system reduces internal heat and reacts quickly to small motions
• Steel dust cover protects the piston rod and seals from UV exposure and road debris
• Tuned high-durometer vulcanized rubber bushings minimize noise, vibration, and harshness (NVH)
• 2-Year Unlimited Mileage Warranty
