MotorbyMotor Universal Window Crank Shaft Extension and Door Latch Shaft Extension

Installation Instructions:

Remove stock door handle(s) and remove the armrest and door panel as required.

Install crankshaft extension over existing shaft and tighten set screw(s) with a 1/8" hex head, Allen wrench to 72-75 inch pounds.

We recommend using Blue Lock-Tite on the set screw to prevent it from backing out.

As a note, the set screw is made of steel with a cone point for the best possible holding capacity.

With proper torque, the pointed end of the set screw(s) will bite to the steel shaft and ensure it won't loosen up over time
Next, re-install the door panel and push the door handle onto the shaft extension.

Check to ensure the clip is engaged into the groove on the shaft extension.


This product will extend your door handle shaft by 5/8" (tolerance is 0 to + 1/16") depending on the length of your existing shaft.

If you need another 1/8" to 1/4" don't bottom out the extension on the original shaft when installing the extension and if you need a little less extension, you can grind down the existing shaft to about where the groove for the c-clip would go ... just be sure the set screw will properly engage the original shaft then install the extension.
