SAFETY: BEFORE BEGINNING INSTALLATION BE SURE TO SET THE PARKING BRAKE

AND CHOCK THE WHEELS.

NOTE: TO EASE INSTALLATION AND PROPERLY ADJUST THE BAR, THE WEIGHT OF THE

VEHICLE MUST BE ON THE SUSPENSION AS IF DRIVING DOWN THE ROAD. DO NOT RAISE
THE VEHICLE BY THE FRAME.

NOTE: THIS UNIT IS DESIGNED TO MOUNT TO THE BOTTOM OF THE AXLE TUBES WITH

THE ARMS OF THE BAR TOWARD THE REAR OF THE VEHICLE.

1. Place the D shaped bushings onto the straight areas of the bar on each side of the center hump.

2. Hold bar up to the axle and locate the position on the axle tubes to mount the u-bolts. Be sure to put the
U-Bolts Under Any Brake Lines, Wires or Hoses on the Axle to Avoid Any Possible Damage. The
threads of the U-Bolts will point down.

3. Place saddle brackets onto the U-Bolts on the axle tubes. Place the U-Plates over the D shaped bushings
on the bar and attach the bar to the U-Bolts and saddle brackets with the flat washers and nuts provided. Install
spacer plates between bushing and saddle if more clearance to the differential is required. LEAVE LOOSE
AT THIS TIME to allow for adjustment later. Remove brake cable/line bracket from axle and use single flat
plate to relocate higher. Also, for additional bar clearance remove the driver side lower shock bolt, turn it
around and reinstall from the opposite side of the lower shock bracket.

4. Locate existing spare tire crossmember on vehicle frame. Place square U-bolt over the frame rail in front of the crossmem­ber with legs of the U-bolt pointing downward.

5. Insert the legs of the U-bolt into slotted holes of the frame brackets. Using 1/2” locknuts and washers, install the frame

9. Align bar from side to side through the D-bushings to be as centered as possible. Rotate bar front to rear by rotating the U­Bolts on the axle. Adjust frame brackets so that the end-links are straight up and down as possible. Be sure the bar does
not contact the differential, shocks, or leaf springs.

10. Torque all of the mounting hardware to the specified rates. Bounce vehicle, checking for clearance on all undercarriage
components, ie: exhaust, shocks, fuel lines, brake lines, etc. Recheck installation periodically on a regular basis.
