Durable Front Shock Upgrade For Massive Lift Kits

If you given your 2017-2025 Super Duty a commanding stance with a 6-8 Inch lift kit, the FOX Performance Series IFP HTO Front Shock is the perfect upgrade for maximizing your truck’s performance and comfort. This premium aftermarket shock is engineered to handle the demands of significantly lifted trucks, ensuring stability, control, and a smooth ride in all driving conditions. One of the key features of this shock is FOX’s innovative Hydraulic Top Out (HTO) technology. This advanced system provides position-sensitive rebound damping by directing shock oil through a secondary shim stack, effectively slowing the shock shaft speed to reduce harsh top-outs. This results in a smoother ride, even with the extra height and aggressive tires. To ensure durability, the 2.5-inch diameter shock body is constructed from impact-extruded 6061-T6 aluminum, which is tough enough to handle just about any adventure you have in mind.

High-Quality Construction & Straightforward Installation

Built for both endurance and performance, the FOX Performance Series HTO features a robust 5/8” hard chrome shaft that delivers durability and smooth operation without compromise. The larger 2.5-inch diameter body increases oil capacity, enhancing the shock's ability to manage heat and improve damping capabilities, which is critical for off-road performance. What's more, the high-flow velocity-sensitive damping system automatically adjusts to changing road conditions, providing a balanced and comfortable ride each time you get behind the wheel. The shock is also fully rebuildable and re-tunable, allowing you to customize and maintain it for optimal performance over time. With its vehicle-specific valving, this shock ensures precise handling and control, whether you're navigating rugged trails or cruising on the highway. Installation is made simple and straightforward as this shock bolts directly in place of your truck's existing components without any extensive modifications.
