Superior Rear Shock Upgrade for Stock to Slightly-Modified Stock Trucks

Upgrading your truck's rear suspension is essential for maximizing stability and comfort, and the FOX Performance Series IFP HTO Rear Shock is designed to deliver just that for 2017-2025 Ford F250 and F350 Super Duty models with 0-1.5 inches of lift. The FOX Performance Series Shock features an innovative Hydraulic Top Out (HTO) technology, which offers advanced position-sensitive rebound damping. By directing shock oil through a secondary shim stack, the HTO technology slows the shock shaft speed, reducing harsh top-outs and ensuring a more comfortable ride, particularly for trucks with heavy and aggressive tires. What's more, the internal floating piston (IFP) design keeps shock oil separate from high-pressure nitrogen, preventing aeration while maintaining consistent damping performance in all conditions. With a pair of these shocks equipped, you can expect more stability and handling for off-road adventures and improved comfort when you're cruising on smooth city streets.

High-Quality Construction for Strength and Durability

Constructed for both durability and optimal performance, the FOX Performance Series HTO Rear Shock includes a robust 5/8” hard chrome shaft for smooth operation even when your driving applications become extreme. The large 2.5-inch diameter increases oil capacity, enhancing the shock's ability to manage heat and improve damping capabilities, which is crucial for enhancing off-road performance. Bette yet, the high-flow velocity-sensitive damping system adjusts to changing road conditions, providing a balanced and comfortable ride no matter where you venture to next. Additionally, this shock is fully rebuildable and re-tunable, allowing for customization and maintenance over time to keep it performing at its best.
