Summary: The FOX Performance Elite Series 2.5 Reservoir smooth body shocks are engineered to provide enhanced ride quality and precise control for the GMC Sierra 1500. Featuring an external reservoir, these shocks increase oil and nitrogen capacity to deliver improved damping and heat management across any terrain. Equipped with Dual Speed Compression (DSC) adjusters, this system allows for high-performance tuning to handle the demands of both on-road stability and off-road impacts.

Features

• External Reservoir: The external reservoir design provides increased oil and nitrogen capacity to ensure consistent damping and fade resistance during sustained off-road operation.
• Dual Speed Compression (DSC): The DSC adjuster provides user-tunable compression settings to ensure the vehicle is optimized for specific loads or terrain conditions.
• Hard Anodized Aluminum Body: The 2.5 inches impact extruded and CNC machined 6061-T6 aluminum body provides superior heat dissipation and rust resistance to ensure long-term durability.
• 7/8 inches Hard Chrome Plated Shaft: The heat-treated alloy steel shaft provides high strength and surface hardness to ensure the longevity of the redundant sealing pack system.
• High-Flow Piston: The race-developed high-flow piston design provides application-specific valving to ensure maximized performance and control.

Frequently Asked Questions

What is the benefit of the external reservoir on this shock?
The external reservoir allows for increased oil and nitrogen capacity, which helps separate the shock oil from high-pressure nitrogen and improves cooling during off-road use.

Can I adjust the damping on this Performance Elite shock?
Yes, this shock features a Dual Speed Compression (DSC) adjuster that allows for manual tuning of the compression settings to match your driving needs.

Will this fit my GMC Sierra AT4 with a 4-inch lift?
No, according to the fitment notes, for AT4 models, this specific part number fits 0-2 inches of lift only.
