the factory bar. If not equipped skip to step 6.
5. To remove sway bar, pull the passenger side of the bar forward and over the idler arm bracket that was disconnected in step 4. Then slide sway bar out from between the pitman arm and frame on the driver’s side.
6. To install the Hellwig sway bar, orient the sway bar with the center hump facing down and the arms extending to the rear of the vehicle. Slide the drivers side of the sway bar between pitman arm and frame until end
link attachment hole is over the lower control arm. Then lift the passenger side of the sway bar over the
disconnected idler arm and into position. It may be necessaryto rotate the idler arm out of the wayto allow
installation of the sway bar.
7. Reattach idler arm to frame and torque bolts to factory specification..

steering ram will not make contact with the sway bar and its components throughout its range of motion.
11. Vehicles without factory installed sway bar: Lower vehicle to the ground so that the full weight of the
vehicle is on the suspension. Then do the following:
a) Install end links and control arm brackets as shown in diagram.
b) Locate sway bar u-plate brackets on frame and control arm for best fit. Make sure that the sway bar
will not contact any frame or steering components as it moves. Ensure that brake, fuel, and transmission lines as well as tie rods and steering components will not make contact with the sway bar
and its components as it moves.
c) When satisfied with the fit, mark holes for control arm brackets on lower control arm. Drill 13/32”
holes in lower control arm to attach control arm brackets. Attach control arm brackets using 3/8” hardware provided.
d) Re-check fit of sway bar and mark holes for u-plate on frame rail. Make sure that the slotted holes in
the u-plates are located outboard as shown in photo (3). When satisfied with fit, drill 11/32” holes in
frame rail to attach bushing u-plates. Attach u-plates using 5/16” hardware provided.
12. Attach end links to control arm brackets as shown in photo (4). If vehicle is to be driven aggressively, it is
recommended that the factory control arm brackets be removed and replaced with the brackets supplied in
this kit (see step 11c and diagram page 4).
13. Tighten all mounting hardware to specified torque.
14. Tighten end links until the bushings bulge slightly.
15. Bounce the vehicle checking for clearance on all under carriage components. Make sure that
the sway bar will not contact any frame or steering components as it moves. Ensure that
brake, fuel, and transmission lines as well as tie rods and steering components will not make
contact with the sway bar and its components as it moves. Test drive the vehicle and recheck all
clearances and the installation alignment. Adjust as needed. Re-check your installation after one week of
driving and periodically on a regular basis.
