Construction & Design

The FOX Performance Elite Rear Shock features a robust 2.5-inch shock body constructed from high-strength aluminum alloy, providing an excellent balance of durability and weight savings. The external reservoir increases oil capacity and improves cooling efficiency, which reduces shock fade during extended off-road or heavy-load driving. Precision-machined components and a sealed cartridge design ensure long-lasting performance and resistance to contamination from mud, dust, and water.

FOX’s proprietary internal bypass technology allows the shock to deliver smooth, progressive damping by controlling fluid flow through multiple circuits. This design enhances ride comfort without sacrificing the ability to absorb large impacts, making it well-suited for both highway cruising and rugged terrain.
