Kit Preparation

Before starting, measure the hub-to-fender height for all four corners of the vehicle to compare with the final results. Park the vehicle on a smooth, level surface, activate the parking brake, and block the rear wheels. Ensure the transmission is in 1st gear (manual) or Park (automatic). Use support stands under the frame rails; do not rely solely on a jack.

Front Removal and Installation

1. Disassembly: Use a vehicle hoist if available, or jack up the front and place on support stands. Remove wheels and factory under paneling. Disconnect the sway bar, tie-rod ends, brake lines, ABS sensor wires, and brake calipers. Remove the rotors, axle nut, and upper/lower ball joint nuts to separate the spindle. Uninstall the strut.

2. Differential and Crossmember: Remove the CV axle, lower control arms, and OEM gravel guards. Disconnect electrical connections and the driveshaft from the differential. Remove the crossmember. Trim the area marked in the instructions for the front crossmember installation and the rear driver's side mount if necessary.

3. Installation: Install differential drop spacers with the tapered end toward the rear. Reinstall the differential, crossmembers, and lower control arms. Install CV axles with spacers. Reassemble the spindle, ball joints, and brake components. Install the compression arm brackets and compression arms.

Rear Lift Installation

1. Disassembly: Jack up the rear of the vehicle from the differential and place on jack stands. Remove wheels and factory shock absorbers. Remove factory u-bolts, carrier plates, and lift blocks. Lower the axle carefully.

2. Installation: Install the new lift blocks on the spring pad with the flat part on the spring and the tapered end toward the front. Align the center pin. Install the new u-bolt hardware and tighten in a crossing pattern. Install the new shock absorbers in factory locations. Reattach brake lines and harness, ensuring there is enough slack. Reinstall wheels and lower the vehicle.

• DO NOT drive the vehicle until all work is completed and checked.
• DO NOT use wheel ramps during this installation.
