GM Truck BRASS Seat Height Adjustment Gears

0.50 LBS

Product Description

Click Here for the Installation Video 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 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. seat height adjustment 5 Star Review

    Posted by on 27th Nov 2020

    Installed as shown on you tube. Works as advertised. Saves me from having to purchase a drivers seat.

  2. Great 5 Star Review

    Posted by on 26th Nov 2020

    I am extremely satisfied with this product. It arrived in about two days and was double packaged. When installing it the fit was great and I needed to use a rubber mallet to get it on all the way. It is definitely made with quality and will last for a long time. Thank you Gruven Parts for making these parts.

  3. Great product that whould have been OEM! 5 Star Review

    Posted by on 5th Oct 2020

    Gears went in easy and work great. Wish GM used these from the factory but so glad someone is making a quality repair part.

  4. Worked great! 5 Star Review

    Posted by on 24th Sep 2020

    This saved me a lot of money. Have to replace both gears. I would recommend taking the seat of the frame to make it easier. One of them is hard to access. Also make sure you clean out the gear housing real good. I had a small piece of broken plastic I missed that gave me problems till I figured out what it was. Take your time and follow the instructions. The video was helpful. This product worked great and high quality. Would definitely recommend.

    Thanks Martin, glad you got the seat height working again. FYI we're now working on the fwd/aft gears as well, so we will have the entire seat covered !

  5. Great Product 5 Star Review

    Posted by on 6th Aug 2020

    This item fixed my seat like new. Better than new because the gears are made of brass and I will never have to fix it again. Parts fit perfectly with no modification needed. Thanks for a great product that is a permanent solution to GM plastic gears. Well done!

  6. Saved Hundreds of $'s 5 Star Review

    Posted by on 6th Aug 2020

    These are awesome! Was able to install the new gears yesterday, and it works perfectly. The install video was perfect. It's RIDICULOUS that the dealer makes you buy a whole seat frame just for one broken PLASTIC gear. These brass gears will likely last longer than I'll be around. LOL

  7. Quick and Easy 5 Star Review

    Posted by on 26th Jul 2020

    Parts were as advertised, installation was straightforward

  8. Worked great for Tahoe 5 Star Review

    Posted by on 23rd Jul 2020

    I followed the instructions and it worked great for 08 Tahoe. The gear was stripped on the seat bottom tilt. I did have to use a fine grinder wheel to take a whisper off the shaft so the new gear would slide on. I have used JB weld many times for various things and it’s a perfect solution for this application.

  9. Quick and Easy 5 Star Review

    Parts arrived quickly, things were as described and the install was east.

  10. Great Upgrade to Failed Factory Gears 4 Star Review

    Posted by on 16th May 2020

    Very excited about the quality of the parts. I did have to file the shaft down a little so the gear would fit. The youtube video was helpful but the location of the gear was not clear from my recollection. The video said 5 thousandth's however the video of the calipers was 0.05 which is 50 thousandths, so I winged it. Would have been 5 stars if there were better instructions on the installation of the gears but overall very happy with the parts
