Make Your 3500HD Look Mean And Ride Smooth

If your GM 3500HD looks tough but still rides like a stock truck, the Fabtech K1051DL 6-inch RTS System with Dirt Logic shocks is the upgrade that gets it all done. It gives your truck the commanding stance you want, the ride comfort you didn’t expect, and the clearance you need for serious tires. The system is built around Fabtech’s patented RTS design that keeps the torsion bars tucked up high in their stock location. That means you’re not dragging low-hanging components across rough ground, and you get way more usable clearance when you’re off-road. With Dirt Logic 2.25 shocks front and rear, you’ll feel the difference immediately in both control and smoothness whether you’re on the highway or climbing trails. This kit is perfect for owners looking to run up to 37-inch tires without sacrificing comfort or reliability. And with a full bolt-on install, you won’t need to cut up your truck to make it happen.

Precision Geometry And Tuned Damping Built For HD Trucks

The Fabtech K1051DL 6-inch RTS Lift System is engineered specifically for 2011-2019 GM Silverado and Sierra 3500HD models, with a focus on proper suspension geometry and high-performance damping. The RTS design keeps the torsion bars in the factory position, preserving ground clearance and improving suspension articulation over uneven terrain. High-arched 1/4-inch thick crossmembers and ductile iron steering knuckles correct steering geometry and maintain strength under load. A front differential skid plate is included to protect vital driveline components during off-road travel. The included Dirt Logic 2.25 shocks feature stainless steel bodies, billet aluminum pistons, and NitroSteel piston rods for long-lasting durability and performance. These shocks are pre-tuned specifically for the increased weight and tire size that comes with a 6-inch lift, helping maintain smooth handling without compromise. This system fits both 2WD and 4WD extended or crew cab trucks and supports up to a 37-inch tire with minor trimming. It's a complete, purpose-built lift solution for HD owners who expect more than just a taller ride height.
