This 2025 GMC 3500HD AT4 came in for a suspension upgrade designed to improve capability, clearance, and overall ride quality.
We installed a Cognito 4" Performance Lift Kit paired with FOX 2.0 Performance Series shocks front and rear. To help maximize tire clearance, the build also included Cognito front fender liner tie-back brackets and a Rough Country mud flap delete kit.
The customer supplied a set of Method wheels wrapped in Mickey Thompson Baja Boss A/T tires, which we mounted and balanced in-house while retaining the factory TPMS sensors. Once the installation was complete, we performed a full alignment to ensure everything was properly dialed in.
