Fabtech's cutting edge RTS system has now been developed for the all new 2011 GM HD platform. This Fabtech suspension lift is designed for use on the new 2011 through 2015 model year Chevrolet 2500HD Silverado and GMC 2500HD Sierra pickup trucks. The 6" RTS Lift System utilizes a patent pending bracket system that keep the torsion bars raised up, in the stock location. This feature provides superior ground clearance at the frame as there are no torsion bars hanging down to become high centered on or damaged when offroading.

The Fabtech K1046DB 6" RTS system has been designed with unitized bracketry to retain the four front compression stops of the vehicle as GM intended. This design distributes impact loads across a wide section of the frame rather than at a single point. Fabtech also includes their now famous High Arched Cross members that provide increased ground clearance over other subframe designs. A front differential skid plate is included that is constructed of 1/4" thick steel that is designed to resist damage caused during hard front suspension impacts. If you own a 2011, 2012, 2013, 2014 or 2015 model year 2500HD and want to lift it the Fabtech K1046DB Dirt Logic kit is an excellent choice. Each Fabtech Dirt Logic shock absorber is built and tuned for a specific vehicle application. Unlike generic "white can" shock absorbers the Fabtech Dirt Logic shocks are designed for use only with a 2500HD equipped with a Fabtech 6" lift. Awesome performance, great looks, and proven reliability make the Dirt Logic kit the right choice when only the best will do.

Fabtech has designed this suspension lift with heavy duty bracketry that allows for a fast installation time and only requires drilling two holes and no cutting of the front diff housing. The Fabtech 6" RTS system allows the use of both 18" and 20" diameter wheels.
