This new system for the redesigned 2015 aluminum-bodied F150s shares all of the great features of the current Zone 6" system for the 2014 model trucks. The system is built around 2 heavy duty 1-piece lower control arm crossmembers and massive ductile cast iron steering knuckles. Differential relocation brackets place the front differential for perfect CV angles and still allow for the factory front driveshaft to perform as is should. The 6" of lift is provided by bolt-on strut spacers that do not require disassembly of the factory struts to install. New eccentric cam bolts make adjusting the alignment easy, sway bar drops adjust the sway bar to its optimum position and a heavy 1/4" thick differential skid plate protects the underside when off driving off road. In the rear, full 5" cast iron lift blocks with integrated bump stop wings provide enough lift to level the truck nicely. Rear Hydro or optional Nitro shocks finish out the installation and provide enough clearance for a maximum sized tire of 37x12.50.Front and rear heavy duty 1-piece lower control arm crossmembers Massive ductile cast iron steering knuckles Full differential relocation bracket system included to properly correct CV shaft angles Includes bolt-on strut spacers - strut disassembly not required New eccentric cam bolts included for easy alignment Includes sway bar relocation brackets to acheive optimum position for sway bar 1/4" thick differential skid plate included 5" Rear Blocks with integrated bump stop wings to acheive a more level stance Rear Hydro shocks included - Nitro shocks upgrade is available.
