These standard kits are designed to retain the factory radius arms by relocating the frame mounting location using a pair of 1/4" steel drop brackets to maintain suspension geometry. The drop brackets key off the factory mounts and tie into the frame for extra strength. Also included in the kit are specially designed gas engine specific progressive rate ProRide front coil springs offering improved performance across all terrains. Also included is a heavy-duty fabricated front track bar bracket, forged drop pitman arm, extended bump stops, brake line relocation brackets, sway bar links, rear block and u-bolt kit along with rear air bag lower spacers and sensor brackets. Rounding out the kits is your choice of BDS NX2 series gas shocks or FOX 2.0 performance gas shocks at each corner. These kits allow for 35-37" tires to be installed.
