Give Your Front End The Performance It Deserves

If your 2020-2026 GM 2500HD or 3500HD has a front-end lift, the FOX 2.5 Performance Series IFP HTO Front Shock is the perfect way to get the control and ride quality your build deserves. This shock doesn’t just handle the rough stuff, it improves how your truck responds to every turn, dip, and bump in the road. With its race-inspired design and external reservoir, it offers consistent damping even when things heat up on tough trails or long highway pulls. The Dual Speed Compression adjuster makes it easy to fine-tune your setup, giving you the right feel whether you’re towing heavy or cruising unloaded. FOX built this shock to handle real work, real driving, and real conditions, without sacrificing everyday comfort. It’s also got the look to match its performance, with anodized finishes and CNC-machined billet parts that make it stand out behind the wheel. When you're ready to take your suspension from basic to bold, this shock brings both the function and the attitude.

Tuned For Precision Ride Control And Lasting Durability

The FOX 987-24-010 shock is a premium-grade suspension solution designed for GM trucks running 1.5 to 2.5 inches of front lift. Its 2.5-inch seamless steel body is zinc plated for corrosion resistance, while the internal floating piston separates oil from nitrogen to eliminate cavitation and shock fade. A 7/8-inch hard chrome-plated shaft ensures strength under load and wear resistance over time. FOX's race-developed high-flow piston design, paired with application-specific valving, delivers smooth, consistent damping across rough terrain and highway miles alike. The Dual Speed Compression (DSC) adjuster gives you on-the-fly control to adapt to changing conditions, while the redundant seal pack keeps moisture and debris out. Every component, from the PTFE-lined spherical bearings to the billet aluminum hardware, is selected for both durability and performance. With 5.18 inches of travel and clevis-to-bar pin mounting, this shock bolts on clean and performs at the top of its class.
