Fox 2020+ GMC Sierra 2500/3500 HD 4-6in Lift Front 2.5 Performance Series Smooth Body IFP HTO Shock

This Fox front shock delivers extended drop-out travel to boost off-road performance on 2020+ Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD trucks with 4-6in lifts. It provides on-road comfort through performance valving that reduces sway for a planted feel. Tuned precisely for these heavy-duty trucks it ensures consistent damping in demanding conditions.

Key Features

  • 2.5 Performance Series Design: Smooth body construction with internal floating piston (IFP) separates oil and gas for fade-free operation during extended use.
  • Aluminum Body: Dissipates heat four times faster than steel keeping shock performance stable under heavy loads and high speeds.
  • Race-Developed Piston: Provides precise valving for balanced compression and rebound suited to 4-6in lift applications.
  • Extended Travel: 9.39in travel (extended 23.52in compressed 14.13in) increases suspension articulation for rough terrain.
  • Eyelet Mounts: Direct bolt-on fit with top and bottom eyelet bushings for easy installation on compatible GM HD trucks.

Product Notes

  • Requires 4-6in lift kit for proper fitment and alignment.
  • Fully serviceable with rebuild kits available for long-term maintenance.
  • Corrosion-resistant finish handles harsh environments and road salt.

Installation Notes

  • Professional installation recommended.
  • Pair with matching rear shocks for balanced ride height.

FOX

FOX is one of the most respected suspension brands in the world, producing shocks, coilovers, reservoir shocks, IFP monotube shocks, upper control arms, and steering stabilizers that are trusted by off-road race teams, overlanders, and performance drivers who require more consistency and damping control than factory suspension can deliver. The brand's reputation was built through desert racing programs including the Baja 1000 and King of the Hammers, where FOX products are validated against the most demanding suspension punishment available before reaching the aftermarket, and that race heritage is directly reflected in the technology and build quality of their Performance, Performance Elite, and Factory Race product lines. Ford F-150, Toyota Tacoma, Toyota 4Runner, Land Cruiser, Jeep Wrangler and Gladiator, Chevrolet Silverado, and Ford Bronco owners choose FOX suspension upgrades as the single most impactful improvement to both on-road ride quality and off-road capability availabl...
