Zone Offroad adds 4" and 6" IFS lift systems to its lineup of products for the 2019-2020 GMC Denali 1500 4WD trucks equipped with adaptive ride control (ARC). These new 4" and 6" IFS systems have been specially designed new trucks to take advantage of the updated OE suspension design for improved offroad performance and capability while maintaining on road comfort and handling characteristics. They join the current 2" leveling kits to offer a more comprehensive suspension solution designed to allow clearance for up to 35" tires. At the heart of these new 4"/6" systems are a pair of 1/4" thick, American steel crafted drop crossmembers to reposition the OE lower control arms. These control arms offer additional ground clearance and are paired with a differential skid plate to create a strong subframe while adding protection for critical steering and driveline components. In place of the factory steering knuckles a pair of specially designed steering knuckles are supplied to maintain proper steering geometry for ESC system compatibility. Unlike most other kits that limit the wheel configurations this knuckle design allows for 17" or larger aftermarket wheels to be installed as well as 20" OEM wheels. Also supplied are a set of heavy duty replacement tie rod ends and weld-in crossmember plate to strengthen the chassis. The front differential is secured in its new location using a multipoint differential relocation brackets to keep the CV axle operating angles at a minimum. The additional ride height comes from a set of top mounted steel fabricated strut spacers that install quick and easily to retain the ride quality and performance benefits of the the ARC struts. Along with ARC sensor relocation brackets this kit is rounded out with a pair of sway bar drop brackets are used to correct the operating angle of the factory sway bar as well as created a strong brace between the rear crossmember and the frame.

In the rear of these 4" and 6" lift kits, the OE lift blocks are replaced with either 3" or 5" lift blocks and longer u-bolts to lift and net a level stance without stacking lift blocks. Rear brake line / ABS line brackets allow the use of factory brake lines. Lower shock extensions are used to allow the ARC rear shocks to be reinstalled to maintain rear damper performance.
