Nitrogen Charged For Faster Response And Smoother Travel

The Zone Offroad 7757 Rear Nitro Shock is engineered for durability and consistent performance on 2001-2025 GM 2500HD and 3500HD trucks. Built around a twin-tube design, this shock features 10-stage velocity-sensitive valving that adapts to varying driving conditions, making it ideal for trucks that see mixed use on and off the road. It’s pressurized with 50 psi of nitrogen gas to reduce aeration and improve responsiveness, especially during rapid compression and rebound events. The Fluon-banded piston helps maintain tight internal control, enhancing long-term performance and keeping the ride smooth even under load. A 14mm heavy-duty chrome shaft and dual welded ends add strength and reliability, while the steel body provides resistance to flex and fatigue. This shock is non-reservoir and non-tunable, keeping things simple while delivering dependable, predictable damping. Bushings and sleeves are included, allowing for straightforward installation as a rear-position replacement shock.
