Product Description

The FOX 985-24-245 2.0 Performance Series Smooth Body Reservoir Rear Shock is engineered specifically for 2020-2025 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks. Featuring a remote reservoir design, this shock increases oil and nitrogen capacity to reduce heat build-up and maintain consistent damping performance during long off-road runs or heavy towing. The race-developed high-flow piston and vehicle-specific valving deliver a balanced ride quality with improved control compared to stock rear shocks.

Constructed with a 2.0" impact-extruded 6061-T6 aluminum body finished in clear anodizing, the 985-24-245 is built for durability and corrosion resistance. Its external reservoir and premium internal components provide sustained performance and confidence in varied terrain and load conditions. Designed for trucks lifted approximately 1.5"-3.0", this rear shock is a solid upgrade for heavy-duty truck owners looking to enhance suspension response, ride comfort, and handling during daily driving, towing, or rugged off-road use.
