The Cognito Front Fender Liner Tie Back Kit is a simple, effective solution for fitting larger tires and more aggressive wheel offsets on 2020–2023 Chevy Silverado and GMC Sierra 2500HD/3500HD trucks.

Designed to address common clearance issues in the front wheel wells, this kit replaces the factory rear lower front fender liner brackets with bolt-on Cognito brackets that pull the liner rearward and out of the tire’s path. The result is increased clearance where it matters most—without cutting metal or compromising fitment.

By tying the lower rear portion of the front fender liner back, this kit allows for significantly larger tire and wheel combinations on leveled trucks while maintaining a clean, factory-style appearance.

Fitment on 3-inch leveled trucks:

• 35x12.50 tire

  • 9-inch wide wheel: -18mm to +18mm offset

  • 10-inch wide wheel: 0mm to +10mm offset

• 37x12.50 tire

  • 9-inch wide wheel: +18mm offset

Fitment Notes

• Factory mud guards must be trimmed if retained, as outlined in the installation instructions

• Intended for front fender liner clearance only; overall fitment may vary based on suspension setup and alignment

• Direct bolt-on replacement for factory fender liner brackets

• No cutting or drilling required

• Designed specifically for GM HD front fender geometry
