Fabtech 20-21 GM 3500HD 4WD 6in Rts Sys w/Perf Shks

Fabtech has been developing aftermarket suspension systems for over 20 years, and they're known for their extensive research and rigorous testing. This 6-inch lift kit for your 2020-2021 Chevrolet Silverado 3500 HD or GMC Sierra 3500 HD is built to enhance your truck's offroad capability without sacrificing the smooth highway ride you need for daily driving. It's designed to retain the factory load-carrying capacity, making it a solid choice if you frequently tow or haul with your truck.

The core of this system is Fabtech's RTS (Rear Torsion System) bracket design. This approach keeps the torsion bars in their original frame location, which significantly improves ground clearance by eliminating hanging torsion bars that can snag on obstacles. This not only protects your suspension but also gives your truck a cleaner appearance. The lower control arm crossmembers are constructed from 1/4-inch thick steel, featuring an arched design for better ground clearance and an integrated skid plate to shield your front differential from impacts. This robust construction ensures strength and rigidity for years of reliable service.

Installation is made more straightforward thanks to the well-thought-out design, requiring only four holes to be drilled and no cutting of the front differential housing. The kit also includes front and rear bump stop brackets to prevent over-cycling of the suspension. The result is a heavy-duty lift kit that offers a great ride and improved offroad performance for your 3500 HD.
