22. On the passenger side mount, cut a 45º section from the pocket as per Illustration 2.
23. On the OEM bump stop flanges on both sides of the truck, cut the front corners to allow
for shock clearance. See Illustration 3.
24. On the front upper A-arm mount pockets, knock the existing alignment cam pins off with
a hammer and grind the surface smooth.
Install Front Suspension
1. Install the provided replacement bump stops (PN 15-11018) to the main cross member
as indicated in Illustration 4. It is important that this is done now as it is not possible to
install these stops after installation of the cross member.
2. With the differential out of the vehicle, temporarily mount the main cross member (PN
82-1459) to the frame using the existing lower A-arm pockets and OEM bolts. Make
sure that the cross member is located with the inside face of the rear flange even with
the rear edge of the OEM bump stop flange as indicated in Illustration 3 (the driver side
should look the same as the passenger side when properly
located). When
the location is
set, clamp the
cross member
to the flanges
to prevent
movement and
drill the 2 upper
mount holes
through the
OEM flange on
both sides of
the truck. The
bottom hole is
not accessible
with a drill at
this time, it
must be
marked for later
drilling. Install
provided 3/8” X
1 1/4” NC bolts,
washers and
Stover nuts and
tighten to
prevent
movement.
Repeat this
step on the
Illustration 3
Passenger side.
Important!
See note 3.
See note 24.
This hole must be
drilled with the cross
member removed.
