FOX 2.5 Performance Series HTO Shocks (Set of 4) | 2020–2026 Chevy Silverado / GMC Sierra 2500HD 3500HD 4WD

Upgrade your truck with the FOX 2.5 Performance Series HTO shocks for 2020–2026 Chevy Silverado and GMC Sierra 2500HD / 3500HD. This is one of the best suspension upgrades you can make to improve ride quality, towing stability, and off-road performance on your Duramax or gas HD truck.

If your truck feels rough, bouncy, or unstable under load, your factory shocks are holding it back. FOX 2.5 shocks are engineered to deliver real performance gains over stock, giving you better control, smoother ride quality, and confidence in every driving condition.

Key Features & Benefits

• 2.5” Aluminum Shock Body
  Larger shock body increases oil capacity and cooling, delivering consistent performance even under heavy load
• Internal Floating Piston (IFP) Design
  Separates nitrogen gas from shock oil to eliminate fade and maintain consistent damping
• HTO (Hydraulic Top-Out) Technology
  Reduces harsh top-out impacts and improves ride quality, especially on lifted trucks or rough terrain
• High-Flow Performance Pistons
  Improves damping response and bottom-out resistance for aggressive driving conditions
• Vehicle-Specific Valving for GM HD Trucks
  Tuned specifically for Silverado and Sierra 2500HD/3500HD platforms
• Direct Bolt-On Installation
  No modifications required, making this an easy and effective upgrade

FOX 2.5 vs Stock GM HD Shocks

Factory shocks on Silverado and Sierra HD trucks are designed for basic comfort, not performance. Once you add weight, larger tires, or hit rough terrain, they quickly fall short.

Stock Shocks:

• Smaller body with limited oil capacity
• Prone to fade under towing or rough roads
• Less control and more bounce
• Harsh top-out feel
• Struggles with added weight and upgrades

FOX 2.5 Performance Series:

• Larger 2.5” body = more oil capacity and cooling
• Fade-resistant under towing and off-road use
• Smoother, more controlled ride with less bounce
• HTO technology reduces harsh top-out
• Handles larger tires, lift kits, and heavy loads with ease

Real Performance Gains You’ll Feel

Upgrading to FOX 2.5 shocks makes an immediate difference:

• Smoother ride over bumps, potholes, and washboard roads
• Improved stability at highway speeds
• Reduced front-end dive when braking
• Less rear-end squat when towing or hauling
• Better traction and control off-road
• Increased confidence at higher speeds on dirt or uneven terrain
