Upgrade the ride quality, handling, and stance of your GM truck with the Fabtech 1.5-inch Sport Suspension System. Designed specifically for 2025 Chevrolet Silverado 1500 Trail Boss and GMC Sierra 1500 AT4 4WD models, this suspension package provides a moderate lift while improving suspension geometry, vehicle control, and overall appearance.

Engineered specifically for Trail Boss and AT4 equipped trucks, this system features Fabtech suspension components paired with Stealth monotube rear shock absorbers to deliver enhanced damping performance and ride comfort. The system is designed to maintain excellent street manners while providing additional clearance and a leveled stance.

Fabtech Stealth shocks utilize a high-performance monotube design that improves heat dissipation, shock response, and vehicle stability compared to factory shock absorbers. This makes the system ideal for daily driving, towing, light off-road use, and adventure-oriented applications.
