If you’re looking to give your 2025 Trail Boss or AT4 just the right amount of lift without going overboard, the Fabtech K1224M 1.5" Sport System hits the sweet spot. It brings just enough ride height to clear taller tires and improve your stance, without the complexity or stiffness of a full lift kit. This system is ideal for drivers who want a cleaner look and better clearance, but still need to keep ride comfort for daily driving. Fabtech includes everything you need in the box, including their Stealth monotube rear shocks for improved control over rough roads or mild trails. Up front, the heavy-duty upper control arms are built to handle extended travel while reducing wear and eliminating suspension bind. It’s all bolt-on, so installation is straightforward and completely reversible if you ever want to return to stock. Whether you’re hitting dirt roads, hauling gear, or just want a tougher look for your truck, this kit is a smart, budget-friendly upgrade that delivers without overcomplicating things.

Designed For Daily Function With Trail Ready Geometry

The Fabtech K1224M 1.5" Sport System is engineered to work in harmony with the unique suspension setup found on the 2025 GMC AT4 and Chevrolet Trail Boss 1500 models. It lifts both the front and rear by 1.5 inches, using front coilover spacers paired with a spring perch spacer to retain factory ride comfort and coil alignment. The system features Fabtech’s extended travel upper control arms with heavy-duty ball joints that eliminate suspension bind at full droop, allowing for smoother, more responsive suspension movement across uneven terrain. In the rear, the included lift blocks and U-bolts provide matching height and proper axle positioning, while the Stealth monotube shocks improve stability and damping. This setup is designed to fit gas models only and does not support trucks equipped with Super Cruise, adaptive ride control, or standard cab configurations. The system also requires aftermarket wheels, as OEM wheels and tires are not compatible due to clearance limitations. With all necessary hardware included and no cutting or welding needed, it’s a practical solution for anyone seeking a reliable and precise lift system that preserves factory drivability.
