Built With Smart Geometry And Race Ready Shocks

The Fabtech 6-inch RTS System with Dirt Logic 2.25 shocks is engineered to raise performance and ride quality without compromising strength or alignment. This setup uses a patented RTS bracket design to keep the torsion bars mounted in the stock location, maximizing ground clearance and improving the truck’s ability to navigate off-road obstacles. Up front, the high-arched 1/4-inch steel crossmembers and ductile iron steering knuckles work together to maintain factory suspension angles while providing durability under load. The included front differential skid plate offers essential protection to the driveline. Each Dirt Logic 2.25 shock features a stainless steel body, billet aluminum piston, and NitroSteel black piston rod to resist corrosion and deliver reliable performance under extreme use. These shocks are pre-tuned specifically for Fabtech’s lift geometry and the added weight of larger tires, offering a balance of control and comfort. The system is compatible with both 2WD and 4WD GM HD trucks from 2011-2019 and is designed to work with extended or crew cab configurations only.
