DANA 300 TWIN STICK SHIFTER KIT

INSTALLATION OF SHIFT RAILS (PARTS #403301 & 403302):

The new shift rails must be installed before continuing on to the remaining instructions. The following is a general
guide that outlines how to install the new shift rails included in this kit. Refer to a service manual for specifics
on replacing shift rails. It is necessary for the transfer case be removed from the vehicle for the required
disassembly. While not required for the installation of this kit, rebuilding the Dana 300 while it is apart may
be a good idea if it has not been done recently. We offer a Dana 300 rebuild kit under Part No. 400300.

1. Remove the Dana 300 pan.

2. Unbolt the cluster shaft retainer and press out the cluster shaft.

3. Remove the cluster gear, making sure to not misplace any of the loose needle bearings.

4. Remove the set screws out of both shift forks.

5. Carefully remove both shift rails out the front of the transfer case, being careful not to misplace the balls and springs.

Before you set the shift rails down, mark them for identification.

6. DO NOT REMOVE THE INTERLOCK PILLS! If the interlock pills are removed, the transfer case will shift into

Low and High at the same time and transfer case damage will result!

7. Using the specific information in the service manual, install the new shift rails into the correct location. (Refer to the

old shift rails to determine which is the front and which is the rear.)

8. USING BLUE LOCTITE, reinstall the shift fork set screws.

9. Reinstall the cluster gear, needle bearings, cluster shaft, cluster shaft retainer, and pan.

INSTALLATION OF SHIFT LINKAGE:

Once the shift rails are in place, continue on to the
shift linkage installation. Note that the original
pivot location was cast into the front output casting
and can be cut off for a cleaner looking installation.
(This is necessary for some Dana 300 transmission
adapters to increase transmission clearance.)

1. Bolt the shifter bracket (#403303) to the front

output casting using the supplied fasteners, #723755,
and #723110.

2. Thread on the 3/8-24" jam nuts and 3/8" female heim

joints onto the end of the shift rails.

Cut off this portion (optional)
