This Fabtech Lift Takes Your Truck From Workhorse To Weekend Warrior

If you’ve been waiting to take your Silverado or Sierra 2500HD to the next level, the Fabtech K1046M 6-inch RTS System is built to make it happen. It gives your truck the stance, capability, and confidence to tackle tougher terrain without sacrificing drivability. What makes this system unique is the patented RTS design that keeps the torsion bars in the factory location, which means no more bars hanging low to catch rocks or trail debris. That added ground clearance really comes in handy when you’re navigating rough backroads or job sites. The kit also includes front and rear Stealth monotube shocks that are tuned for oversized tires and daily comfort, so the ride feels smooth even when the pavement ends. With room for up to 37-inch tires and a true bolt-on design, it gives you serious presence without cutting into your frame or your budget. Whether you're chasing off-road adventure or just want your truck to look like it means business, this system checks every box.

Precision Engineering And Smart Geometry Make This Lift Stand Out

The Fabtech 6-inch RTS System is designed for 2011-2019 GM Silverado and Sierra 2500HD trucks and stands apart with its unique torsion bar relocation system. Instead of dropping the torsion bars like many traditional lift kits, this patented setup keeps them in their original position to preserve frame clearance and improve off-road capability. At the core of the system are heavy-duty 1/4-inch thick high-arched crossmembers and ductile iron steering knuckles that maintain strength while correcting geometry for the lift. The included RTS brackets ensure proper alignment and smooth operation of the suspension system. Stealth monotube shocks feature a 46mm high-flow piston and 50mm seamless body for consistent damping, even with larger wheels and tires. Their Nitrocarb piston rods provide superior corrosion resistance and hold up well under tough conditions. This system is designed for extended and crew cab trucks, fits both 2WD and 4WD, and is compatible with wheels 18 inches or larger. It's a complete package engineered for long-lasting performance, both on and off the road.
