Product Description

Click Here for the Installation Video

GruvenParts.com is PROUD to release this LIFETIME WARRANTIED SOLID BRASS GEAR SET for 2007-2014 GM truck power seat height adjustment mechanisms !  This set includes 1 helical cut solid brass main gear AND a solid brass mating worm drive gear.  Do NOT just replace the spur gear, you need both the brass spur and mating brass worm gear for a bulletproof mechanism.  These gears exactly match the GM plastic versions but are many times stronger so they will not chip, strip, or break.  This is a GREAT WAY to save money AND make your GM truck seat power height adjustment mechanism BULLETPROOF!  We all know that GM will not sell these gears - instead, they make you buy an entire new power seat unit (with more plastic gears that will also soon break or strip).  Don't waste money on more plastic gears, or incomplete gear sets.  The GruvenParts.com gear set includes EVERYTHING that wears out and replaces them with SOLID BRASS GEARS - LIFETIME WARRANTIED !

The larger helical cut spur gear easily attaches to the main shaft via 24 hour cure epoxy, such as 24 hour JB weld 8265S (readily available at Home Depot, or on Amazon).  You can quickly and easily remove the remnants of the GM plastic gear using a small dremel tool then just clean the underlying shaft before application of epoxy.  The brass worm gear simply replaces the cheap plastic worm gear in the unit.

This product is sold as a set of 2 gears - (1) Brass Spur Gear and (1) Brass Worm gear.  This is enough to fix ONE (1) power height adjustment mechanism.  Please note there are TWO (2) power height adjusters on each seat - one for the seat front and 1 for the seat back.  This does not fix the power forward / aft or seat recline features.

This product fits all 2007-2014 GM Trucks with Power Seats, Including Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali, and likely many others.  The part numbers for the seat tracks which these gears fit into are : 22-80-44-17 (228044170, 22-80-44-18 (22804418), 22-80-44-19 (22804419), 22-80-44-20 (22804420), 20-77-91-09 (20779109), 20-77-91-10 (20779110) as well as many others.  This part number list will continually grow !

 

** Installation Instructions ** 

1. Access bottom of seat structure.  This is easiest by removing power seat entirely from vehicle.  Remove power seat bracket from bottom of seat bottom.

2. Remove the flexible drive shaft for the height adjustment drive box.  You can pull the drive box away from the drive shaft slightly to gain the needed clearance.  The flex drive shaft will fall out.  Please be sure to mark the drive shafts if you are replacing both height gear sets as the drive shafts are different lengths.

3. Remove the Four (4) 1/4" screws holding each height adjustment drive box together.  Remove and discard the plastic worm gear.  Position the main spiral shaft with over-molded plastic spur gear such that the plastic spur gear can be cut off using a dremel wheel or similar.

4. Cut across the width of the plastic spur gear.  Its OK to cut slightly into the underlying steel shaft.  Wear eye protection !  Remove the old plastic spur gear and clean off the underlying steel shaft.

5. Using a 24 hour epoxy such as JB Weld 8265S, thoroughly coat the steel underlying shaft.  Slowly thread on the new brass spur gear, wiping away any excess JB weld.  Once the JB weld dries, it is extremely hard to remove so clean any excess epoxy.  Position the new brass gear such that the metallic washer recess is facing the spirals, just like the OEM layout.  There should be about .050" of main shaft exposed (not including shaft ball end) once new brass gear is installed.  You can also look at the OTHER height mechanism and measure its gear placement.

6. Allow epoxy to fully cure per manufacturers instructions. 

7 Reassembly is reverse of removal.

  1. Siilverado Seat Gear 5 Star Review

    Posted by on 7th Jun 2022

    Solid brass construction. Well machined items. Purchased to replace broken OEM plastic seat recline gears.


  2. it works 5 Star Review

    Posted by on 6th May 2022

    Arrived quickly. Follow video instructions. Recommend dry fitting first. I had to lightly file the shaft to get the gear to slide on. Recommend measuring gap during dry fit, then marking the farthest point behind the gear to make sure it does not inadvertently move after applying JB Weld. Seat moves like new now. Also, recommend replacing seat cushion foam at this time, since the gear replacement puts you halfway there.

  5. Got seat working 4 Star Review

    Posted by on 20th Feb 2022

    My application was 08 suburban driver seat with electric forward/ backward and two up/down adjustment motors. My front up/down adjustment gearset broken which is actually the middle motor of the three. Two brass gears come in the kit. My seat had one steel worm gear that I reused and one broken plastic wheel (driven) gear that I replaced with one out of the kit. The brass worm gear in the kit may be needed in a different application, but in my case the factory worm gear was a better fit in the plastic gear cover housing assembly. There are videos of how to remove old gear with a dremel on youtube. Once removed I used a file to slightly reduce shaft dia. So that the new gear would fit up over shaft. Clean well. I used carb cleaner. Roughed up inside surface of gear then jb weld. Gravity was not a friend so prop it to keep gear stationary for 24 hours while hardening. I left aprox 1/32 inch shaft sticking out beyond gear..the ball bearing in end of shaft rides on metal disc. Watch this small thrust disc part may fall out upon disassembly. Needed for proper gear lash. Clean old grease and broken plastic chips out of gear housing halfs. I used silicon grease packets for brake caliper pins from orileys as lubricant on reassembly. Tested seat with 12 volt supply. All working now. Time to re install seat.

  8. Sturdy Product 5 Star Review

    Posted by on 7th Oct 2021

    Like the product very much, a lot more robust than cheap plastic factory part. Installation guide very informative and helpful. Does take some time to do the repair but well worth it. A lot cheaper than trying to locate a replacement adjuster and hope that it is not stripped as well. Would recommend!
