Shaft Kit Installation
This kit includes two U-joints & a small spline shaft. During our R&D we found that with stock
manifold exhaust or TTI headers, two U-
Joints and a very small section of ¾” DD shaft were more
than adequate. The pinion size o
n 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) When using the stock column, cut the column shaft off just above and as close to the factory
U-Joint as possible. The column does not even have to be removed for this step. Install the
column clamp over the column and position on the column tube, then tighten down.. Make sure
the cut on the end of the shaft is even and then drill and pin the Upper U-joint #8050360 to the
column 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 4
5˚ 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.
To Mis-Phase the U-Joints, the Groove of the upper U-
Joint must be aligned or rotated 45˚
away from the Groove of the lower U-joint as shown in the illustration below.
4) Reinstall the shaft with the U-Joints 45º out-of-phase, then tighten Pinch Bolts of U-Joints to 20
ft/lbs. Be sure to remember to tighten up the mounting hardware for the rack. Torque the
mounting bolts to 45 ft/lbs.
