Shift Arm Kits

Q: What transmission will your kit fit?
A:Any GM 3 & 4 speed automatics.

Q: What does it do?
A: This kit contains all the parts and hardware to hook up any column shifter to any GM transmission, 3 or 4 speed, regardless if the shifter was for a 3 or 4 speed.

The key is out billet aluminum splined button. This button slides on the selector shaft of your transmission replacing any bracket that may have been there originally. Once the button is fastened on your transmission (with standard or metric nut supplied) than the rest is easy. Our shift arm also is splined to match the button until you find the right angel and tighten the clamping bolt. Next, you simply hook up the linkage rod from the lever of the column to the shift arm. Bending of the rod is sometimes necessary, but the ball pivot joints have about 20° of movement each, so proper alignment is expected. Slide the pivot joint on shift arm slot for short or long throw and proper shift indicator alignment.

Q: Do you have a kit for Ford or non GM transmissions?
A: No.

Q: What is stainless steel?
A: The shift arm, rod and washers.

Q: What length kit do I need?
A: We have two lengths, long and short. The long rod is 22" long and has 4" of 5/16" fine thread on each end. Bolt to bolt extreme measure are 17-1/2" to 23-1/2". Short rod is 15" also 4" of thread on each side, extreme measures are 10-1/2" to 17". Most cars from Model A’s to 1948 use the short rods – everything else takes the long rod.

If you measure the distance from your column shift (in the park position) to your selector shaft of your transmission, subtract three inches, that is usually the length of rod you need (unless bending is required).

Q: Can I cut the rod thread myself?
A: Yes, but these rods are thread rolled so the unthreaded part of the rod is 19/32. The new threads will look a little flat, but for this application we feel it is safe.

Q: Would it work if I have a floor shift?
A: Yes. Then you can buy just the shift arm only, no linkage kit.
