Fabtech 20-21 GM 2500HD 4WD 6in Rts Sys w/Perf Shks

The 1/4" thick steel construction of the lower control arm crossmembers, arched for superior ground clearance, is a key feature of this 6-inch lift system for your 2020-2021 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD. This design, part of Fabtech's RTS (Rear Torsion System) approach, keeps the torsion bars in their factory location. This means you get improved off-road capability without the torsion bars hanging down, which helps prevent getting hung up on obstacles and maintains a clean look under the frame. It also retains your truck's factory load-carrying capacity, so you can still tow and haul with confidence.

Fabtech's RTS bracket system is the heart of this lift, indexing the torsion bars at their factory setting to ensure a comfortable highway ride. The kit includes heavy-duty bracketry, also made from 1/4" thick steel, adding significant strength and rigidity to your suspension. The near-factory track width is maintained, which helps keep your larger tires tucked neatly under the fenders. To prevent over-cycling the suspension, front and rear bump stop brackets are included. The arched crossmembers not only provide ground clearance but also come with a skid plate to protect the front differential from impacts during off-road excursions. Installation is made faster with only four holes needing to be drilled and no cutting of the front differential housing required.

This lift kit is built with high-quality components designed for years of trouble-free service and an improved ride. It includes performance shocks to complement the suspension lift.
