43. Place one of the large 5/8” washers over the 5/8” bolt
inside the control arm mount and then thread a nut onto
the bolt. Tighten to 80 ft/lbs.
44. Repeat steps 40-44 for the other side.
45. The next few steps involve mounting the Watts Link.
Locate the billet aluminum Watts pivot, the double shear
reinforcement plate, (2) 3/8” x 3.75” bolts, and a ½” x 4”
bolt. Refer to Image 22 for a visual representation of
these components assembled. 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.
46. Once a mounting location has been
determined, tighten the center bolt to 80
ft/lbs. and the smaller outer bolts to 35 ft/lbs.

47. 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 ride
height is established, tighten the collar on
the shock and proceed to the following step.
