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. Lubricate the D shaped bushings and place them on 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. The saddle brackets have different radiuses to match the taper of the axle. Install saddles on axle
so that they sit squarely on the axle. 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.
LEAVE LOOSE AT THIS TIME to allow for adjustment later.
4. Remove brake cable/line bracket from axle and use z-bracket and 5/16 bolt and nut to relocate as
shown in photos.
Remove the driver side lower shock bolt, turn it around and reinstall from
the outboard side of the lower shock bracket.
