36. Support the rear end and loosen the large bolts
that attach the torque arm to the rear
differential mounting plate using a 1-1/8”
socket. (Image 18)
37. Once the torque arm bolts have been removed,
install the BMR Watts Link mount as shown
in Image 19. Re-install and tighten the
mounting bolts to 150 ft/lbs.
38. The next few steps involve mounting the
Watts Link. Locate the billet aluminum Watts
pivot, the reinforcement plate, (2) 3/8” x 3.75”
bolts, and a ½” x 4” bolt. Refer to Image 19
and 20 for a visual representation of these
components. NOTE: If your vehicle will be
setup for a low ride height, choose one of the
lower sets of mounting holes to install the
Watts pivot. For most applications, this is a
good starting point. This mounting point,
along with the outer Watts linkage mounting
points, determines the vehicles rear roll center
(RC) height. Variances in vehicle center-of-
gravity (CG) height make multiple mounting
locations necessary for fine tuning RC height.
39. Tighten the center bolt to 80 ft/lbs. and the smaller outer bolts
to 35 ft/lbs.
40. Before mounting the Watts link bars, it is necessary to load the
vehicles suspension. Allow the weight of the vehicle to sit on
the rear end and bounce the car a few times to settle the
suspension. If the car sits too high or too low, use the provided
spanner wrench at this time to adjust the spring height on the
shocks. If it is not possible to adjust the springs enough to
achieve the desired ride height, move the lower shock
mounting hole to a different location. Once the desired spring
height is established, tighten the jam collar on the shock and
proceed to the following step.
