Experience A Lift That Delivers Performance Comfort And Confidence

If you’re ready to take your 2025 Silverado or Sierra 1500 4WD to the next level, the Fabtech K1219DL 6" Performance System with Dirt Logic shocks is the kind of upgrade that changes everything about how your truck drives and feels. This system gives you a true six inches of lift, creating the clearance you need for larger tires and a bolder, more capable stance. The ride quality, though, is what really stands out. Fabtech’s Dirt Logic coilovers and rear shocks are made with stainless steel bodies and NitroSteel piston rods, giving you a smooth, controlled feel over any terrain. You’ll get better comfort on pavement and serious composure off-road, whether you’re hitting rocky trails or rough backroads. The geometry is tuned for excellent steering response, so even with the lift, your truck still handles predictably and confidently. Built tough in the USA and backed by a 5-year, 60,000-mile warranty, this kit combines rugged performance with everyday drivability in a way few lifts can match.

Precision Built Suspension Engineering For Real World Control

The Fabtech K1219DL 6" Performance System is engineered to deliver high-performance handling and off-road durability while maintaining factory-like driveability on the 2025 Silverado and Sierra 1500 4WD. This system uses Fabtech’s proven IFS suspension design, which eliminates bump steer throughout the suspension cycle to keep your steering smooth and consistent. Up front, the Dirt Logic 2.5 coilovers replace the factory shocks, offering superior damping and control with corrosion-resistant stainless steel construction. The heavy-duty quarter inch thick steel crossmembers include OE-style cam pins, allowing easy alignment adjustments using factory cams. Fabtech’s proprietary steering knuckles maintain the truck’s tight turning radius, and triple differential mounts ensure proper driveline angles with minimal vibration at highway speeds. In the rear, Dirt Logic 2.25 shocks pair with 5-inch lift blocks and round U-bolts for balanced ride height and improved stability under load. This system fits V8 gas models with crew cab, short bed configurations and is not compatible with Super Cruise, Trail Boss, AT4, or magnetic ride control models. Every component has been designed to work together for a lift that performs as great as it looks.
