Shaft Kit Installation
This kit includes two U-joints, a small spline shaft, and a shaft support bracket and heim joint.
During our R&D we found that with stock manifold exhaust or TTI headers, this kit was more than
adequate. The pinion size
on the Mopar rack is ¾”-36; for the stock column, the column shaft is
¾” Smooth. If you have an aftermarket column, a U-joint of the appropriate size will be required.
1. The column will not need to be removed for this step. When using the stock column,
disassemble the factory u-joint (shown above) by removing the metal retainer and pulling the
outer shell off exposing the roll pin used to hold the joint on the shaft. Cut the shaft as close
and evenly to this roll pin as possible. Next slide the heim joint 8050760 over the shaft and
assemble the joint to the support bracket 8021880; leaving roughly three to four threads
exposed on the bottom of the nut. This will give you a reference point to mount the support
bracket to the frame rail. Support bracket should positioned as shown in the picture below.
Attaching the bracket will require drilling two 7/16 holes through the bracket and the frame
rail. Use the supplied hardware, 231280 (2), 200850 (4), and 120490 (2) to mount the
bracket. Depending on your application it maybe necessary to fine-tune the height of the
shaft by simply adjusting the support bearing up or down, utilizing the threaded portion of the
support bracket. Finally slide the upper U-joint 8050360 over the shaft, drill and pin the joint
to the shaft.
2. Place the second lower U-joint #8050240 onto the pinion of the rack, insert & loosely tighten
pinch bolt, use this to mock up & measure the length of ¾” DD shaft needed.
MEASURE CAREFULLY!
Trim the ¾”DD shaft accordingly, making sure the shaft is flush with the edge of the inner yoke
(see illustration on next page). Then grind a groove for the pinch bolt.
3. You are now at the point where you need to line up the U-joints on
the shaft so that they are 45˚ out of phase. This will help insure that
there will be no binding when turning. 45˚ out of phase looks as
pictured below: the Grooves or slots for the U-Joint pinch bolts are
off set by 45˚. The lower U-joint which fits to the rack and to the DD
side of the shaft, can only fit on one way, the Groove of the U-Joint
lines up in the middle round side of the DD shaft. The Upper U-Joint
#8050360 which fits the column and the splined end of the shaft can
be rotated to fit on the splined at various degrees.
