Fox 2020-Up GM 2500/3500 HD Perf Series 2.0 Front Smooth 1.5-2.5in Lift - Requires Up Control Arm

FOX Performance Series 2.0 front smooth body shock upgrades the suspension on 2020-2024 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD trucks. This shock delivers race-proven velocity-sensitive damping for a ride that stays comfortable on pavement while providing precise handling on rough trails. Engineered with an internal floating piston (IFP) it separates oil and gas for consistent fade-free performance under heavy loads or high speeds.

Key Features

  • Race-Proven Damping: Velocity-sensitive valving restores factory ride quality with improved control over bumps and high-speed off-road terrain
  • 1.5-2.5in Lift Compatibility: Designed for stock height to mild lift setups pairs perfectly with upper control arms for proper geometry and alignment
  • Smooth Body Design: Aluminum construction dissipates heat faster than steel reduces unsprung weight for quicker response
  • Precision Components: Hard-anodized aluminum body 1-inch diameter shaft with DuoBushing system and PTFE-infused seals for leak-free durability
  • Extended Length 25.99in Compressed 16.51in Travel 9.48in: Eyelet top/bottom mounts ensure direct bolt-on fit with OEM or aftermarket components

Product Notes

  • Requires aftermarket upper control arms for proper installation and alignment
  • Sold individually typically driver side use companion part 985-24-245 for passenger side
  • Position-sensitive tuning optimized for HD trucks with heavy payloads

Installation Notes

  • Professional installation recommended.
  • Upper control arms required to achieve 1.5-2.5in lift without binding or alignment issues
  • Eyelet mounts compatible with OEM hardware torque to factory specs after alignment
