Take your late model 2011-2015 Chevy Silverado 2500HD or GMC Sierra/Denali 2500HD to the next level with Zone Offroad. These 3" Adventure Series UCA Lift Kits bridge that gap between an entry level leveling kit and full IFS lift system offering next level performance without the cost and extensive installation. The heart of this new system is a pair of heavy duty replacement upper control arms (UCAs) designed to improve range of motion for more suspension travel when wheeling in rough terrain. These new control arms dwarf the factory units and are built from 1/8" steel, boxed and fully welded with CNC-machined bushing and ball joint cups repositioned to operate in the neutral position at 3" of lift. They use OE durometer rubber bushings and greaseable OE-style heavy duty ball joints for quiet, reliable operation and superior corrosion resistance to uniball style control arms.

Along with the arms, a pair of reindexed cast steel torsion bar keys are supplied up front to lift vehicle. Zone Offroad includes a small differential relocation kit (4WD models only) to correct CV axle operating angles without effecting ground clearance. In the rear a 2" block and u-bolt kit is used to create a level to slightly tail high stance. Rounding out the kit are a set of Nitro gas shocks at all 4 corners for a smooth ride and impressive performance across any terrain. Take your late model GM 2500HD to the next level with Zone Offroad Products!

Will this kit work on my 2011 4×4 2500 he deisel with 285/75/R17 34″ tall tired with 17×9″ Mega Mayhem rims not sure if offset tire are rubbing now on plastic fender walls

Hey Bud, its hard to give a definitive answer as to if some trimming would be needed, but you should be good with that particular setup. Wheel backspacing will play a factor as well as how you plan to use the truck (on or offroad) as to the amount of trimming that may be needed. Its common to trim front lower valance and rear inner fender slightly on the GM trucks to maximize tire clearance with any lift.
