These lift systems are designed to convert the factory radius arm over to a stronger 4-link design offering improved stability, handling and articulation. The kit is designed with 1/4" fabricated 4-link brackets that key into the factory radius arm pockets for added strength. The 4-link design improves handling and drivability by limiting castor change to less than 1-degree throughout wheel travel. These kits also include 6" diesel engine specific progressive rate front ProRide coil springs, a heavy duty front track bar bracket, forged drop pitman arm, extended bump stops, brake line relocation brackets, sway bar correction, high clearance transmission crossmember and transfer case indexing ring, rear block and u-bolt kit along with rear air bag lower spacers and sensor brackets. All kits are finished off with your choice of BDS NX2 or FOX 2.0 gas shocks at all 4 corners. These kits allow for up to 37" tires to be installed.
