Part Number: 985-26-192

Summary: The FOX Performance Series 2.0 Reservoir shock absorbers are designed to provide industry-leading performance for the GMC Sierra 2500/3500. Featuring a 2.0 inches smooth body reservoir and compression adjustable technology, these shocks address the need for enhanced heat dissipation and user-tunable damping. The external reservoir increases oil and nitrogen capacity, ensuring predictable ride quality and the ability to handle rough road conditions without performance fade.

Features

• External Reservoir: 2.0 inches Smooth bore 6061-T6 Aluminum hard anodized construction provides increased oil and nitrogen capacity to ensure consistent damping during aggressive use.
• LSC Adjuster: Low Speed Compression (LSC) adjustment functionality provides user-tunable damping control to ensure the vehicle is optimized for specific loads or terrain.
• Aluminum Body: 2.0 inches Impact extruded 6061-T6 aluminum provides superior heat dissipation and rust resistance to ensure long-term durability and performance.
• High-Flow Piston: Race-developed high-flow piston design provides application-specific valving to ensure maximum performance and ride quality.
• Redundant Sealing Pack: Main seal, wiper seal, and scraper seal system provides a robust barrier against contaminants to ensure seal integrity in harsh environments.

Why Choose This Product?

• Engineering Advantage: The use of impact-extruded 6061-T6 aluminum and an external reservoir allows this system to dissipate heat significantly faster than conventional steel shocks, preventing damping fade.
• Performance Benefit: The Low Speed Compression (LSC) adjuster allows drivers to manually tune their suspension to match specific road conditions or vehicle weight, resulting in a more controlled and predictable ride.

Frequently Asked Questions

What does the LSC adjuster do?
The Low Speed Compression (LSC) adjuster allows you to tune the shock’s damping characteristics to better handle specific terrain or vehicle loads.

How does the reservoir improve performance?
The external reservoir increases the total oil and nitrogen capacity of the shock, which helps reduce heat buildup and maintains consistent performance during extended use.

Are these shocks resistant to rust?
Yes, the 6061-T6 aluminum body is clear-anodized and the reservoir is hard-anodized, both of which are designed to resist rust over time.
