If installing product on 2000-01 models, it may
be necessary to replace the rubber support
cushion and support bracket with parts from a
1999 or earlier model. The slightly different
assembly used on some later vehicles is not
compatible with the HD X-Member.
Replacement with a compatible support cushion
and bracket assembly from a 1999 or earlier
model must be performed before HD X-Member
can be installed.
To determine if your support cushion
assembly is compatible, measure the
OE crossmember as indicated below.
A distance of 16-5/8”
(A)
indicates that the
vehicle is equipped with the incompatible
support cushion assembly, whereas a distance
of 15-5/8”
(B)
indicates a compatible support
cushion assembly.
4. INSTALL HD X-MEMBER
Support the HD X-Member beneath the vehicle
in the same location as the OE crossmember.
HINT

original mounting holes in chassis rails. Install
original hardware and tighten to 31 ft-lbs. using
a torque wrench.
Carefully lower the hydraulic jack and align
threaded studs of support cushion with holes in
HD X-Member.
Install the original nuts and tighten to 16 ft-lbs.
