Improved Off-Road Performance for Lifted Super Duty's

Upgrading the rear suspension on your lifted 2005-2025 F250 or F350 Super Duty can make a world of difference in your truck's overall performance, providing exceptional stability, control, and comfort each time you set off for adventure. That's exactly where the FOX Performance Series IFP HTO Rear Shock comes to play as it works to ensure your truck performs at its very best. At the core of this shock is FOX’s innovative Hydraulic Top Out (HTO) technology. This cutting-edge feature enhances position-sensitive rebound damping by channeling shock oil through a secondary shim stack, which slows the shock shaft speed and reduces harsh top-outs. The result is a smoother, more controlled ride, particularly for trucks equipped with heavier and more aggressive tires. The shock also features an internal floating piston (IFP) design which separates shock oil from high-pressure nitrogen, enhancing heat dissipation while maintaining consistent damping performance over time.

Heavy-Duty Build for Enhanced Durability

Built to withstand just about anything you throw its way, the FOX HTO rear shock features a 5/8” hard chrome shaft for impressive durability and smooth operation. It also comes standard with a large 2.5-inch diameter to increase oil capacity over stock, improving the shock's ability to manage heat and enhance damping capabilities. The high-flow velocity-sensitive damping system adjusts to varying road conditions, delivering a balanced and comfortable ride. Additionally, this shock is fully rebuildable and re-tunable, allowing for customization and maintenance over time to keep it performing optimally. Better yet, installation is made simple and straightforward as this shock bolts directly to your truck's suspension without the need for a ton of hassles.
