Each installation may vary due to chassis manufacturing options and variations in design. The rod assembly
may be installed in several different combinations, such as either front or rear of the supplied brackets as well
as using different bracket holes. The important thing is to maintain clearance between your UltraTrac and any
chassis component (moving and stationary) such as exhaust, vehicle frame, differential, or any other item
which might interfere with the operation of this product. Pictures and diagrams may not represent the best
installation for every application.

Install the frame bracket and pinch plate
on the frame rail. The frame must be
between the pinch plate and frame
bracket. The frame bracket is designed
to mount to the bottom and the sides of
the frame rail. Position the frame bracket
below the frame rail on the passenger side
in line with the axle bracket. Align the slotted
holes in frame bracket with threaded holes in
pinch plate. (Place the nut plate with lip
facing down and towards the center of the
vehicle). Install (2) 5/8”x2” fine threaded bolts,
(2) 5/8” lock washers & (2) 5/8” flat washers
Tighten “just snug” for now.
Remove and discard the 4 bolts, 2 on each
side that hold the sway bar on the differential
housing. On the driver’s side insert the mounting
bracket underneath the sway bar bracket
to accept the 4 square head set-screws. Tighten
the set-screws down equally until they contact the
bracket that is welded to the differential. This
will stop the lateral movement of the bracket.
On the passenger side insert spacer plate
between sway bar brackets and differential.
Install bolts supplied in kit.
On earlier and lighter chassis the sway bar
brackets are held on with 10mm bolts. We
suggest that you remove the bolts and the
nuts that are tacked on the differential and
replace them with the 12mm bolts that are
included in the kit. On some models, 12mm
bolts are used. If 12mm bolts are used, replace
them with the longer bolts that are included
in the kit. Tighten to 45-55 ft. lbs.
