CHEVROLET Tahoe 2007 - 2014 Up/Down Power Seat Motor All Steel Gear Kit is perfect for replacing stripped gears  in your existing motor.  This kit uses a small metal worm gear and a metal large gear mounted on a custom machined shaft.
 
You will need to use the provided front thrust washers and your factory rear thrust washer. The small thrust washer on the small worm gear must also be reused along with your factory tube nut.
 
If you want a factory style small worm gear, see the other product. Two metal gears meshing together cause a noticeable gear whine.  Watch both videos to hear the difference between a factory style worm gear and the metal one.
 
This kit has a lifetime warranty covering any gear breakage.
