GruvenParts.com is PROUD to release this LIFETIME WARRANTIED SOLID BRASS GEAR SET for 2007-2014 GM truck power seat forward/aft adjustment mechanisms ! This set includes 2 helical cut solid brass main gears which is made in 2 sections AND steel seat frame repair bushings. 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 fwd/aft 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 !
This product is sold as a set of 2 brass helical gears, 2 brass gear journal bearings, and 2 steel frame repair bushings. Enough to fully repair the fwd/aft gears on 1 seat. Driver and passenger seats both use the same gears.
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 (and we will be making a pdf with pictures soon too -- if you are handy with the camera let us know, we can offer free parts for helping us make a good DIY ! ) **
1. Access bottom of seat structure. This is easiest by removing power seat entirely from vehicle. Turn seat upside down and remove the bottom seat cushion.
2. Locate the front main cross member which the seat drive units are connected to. You will need to grind the rivet heads on either end of this bar such that you can slide it out of the seat structure. Do not cut into the seat bar itself, just remove the rivet head.
3. Oversize the hole to 1/2" which the seat frame bar was riveted into. This will fit the steel repair bushings. You can remove any sharp burrs and apply some black primer to the cut areas to protect the seat structure from corrosion.
4. Slide off the seat fwd/aft gear boxes. There are retaining rings at the front and back of each gear box. Use a thin flat head screw driver to remove the retaining rings. The gear box will then open up, revealing a plastic drive spur gear and worm gear. Using a cutter such as a dremel tool, remove the spur gear which is over-molded onto the long spiral drive shaft. Its OK to cut slightly into the underlying steel long spiral shaft. Completely remove the plastic spur gear and clean off any burrs or sharp edges using sand paper. You will re-use the OEM worm gear as this gear does not typically fail.
5. Slide the supplied brass bushing with hat section 1st onto the long spiral shaft at the far end. Slide the brass spur gear onto the shaft from the short end. Test fit and make sure they sit concentric to the long spiral shaft (within reason, we're not needing .001 inch concentricity here as the gears dont spin very fast).
6. Use a 24 hour epoxy, such as JB 24 hour weld (NOT the 5 Min version) to bond both halves of the brass gear onto the main spiral shaft. Allow to cure for 24 hours. Make sure you wipe off any excess epoxy from gear teeth as it will dry very hard.
7. Install long spiral shaft into gearbox and place retaining rings on front and back sides.
8. Reinstall all components onto the front frame bar as they were removed and use the steel repair bushings with hat side facing out to locate the previously cut frame rail. Use epoxy such as 24 hour WB Weld (not the 5 minute version) to bond the circular frame rail section to the inner diameter of the steel repair bushing. Allow to fully cure. If you have access to welding equipment you could also weld the frame bar to the steel bushing but make sure it can rotate as its needed for the seat height mechanism.
9. Reinstall the seat cushion and seat into vehicle.

Forward and aft seat gears. inexpensive fix to a normally expensive problem
Posted by Aaron Byrnes on 14th May 2024
Easy to install if you are handy with tools. I installed mine without removing seat bottom from the frame.

glad i kept looking for a solution to my problem.

The only thing that I would change would be the video attached to this product.
There are things that I would change such as just flipping the bushing around. It would not need to be JB welded. I also use a saws all to cut off the weld, which left the end of shaft nice and clean.
If I do this again, I will definitely make my own video to share.

Parts are Working

The parts fit and are in the chair. The price was a bit high. The chair is functioning and that is worth the money.

Good product, but could be improved
Posted by Eduardo on 28th Dec 2022
I agree with previous reviews that both the video and written instructions are missing key steps that would help most save a lot of time. When I installed the bushings on the end of the shaft I noticed they fit very lose. After I installed the seat everything works great, except now I feel my seat move forward and back every time I brake or accelerate. I looked into it and found that the lose tolerance of new bushings is the problem. The shaft is shifting back and forth in the bushing due to excessive play. Now I have to figure out how to address that problem.
-- response --
What bushings are worn out ? We can probably make these too, please contact me.

Works Great, Nice Repair!
Posted by Marcus on 2nd Sep 2022
This is a nice kit to replace the gears in the FWD/AFT motion drive. I installed it on a 2007 Suburban driver's seat.
I used a Dremel with cut-off wheels to cut off just the rounded heads of the rivets on the ends of spiral shaft. At that point I couldn't see a seam in the metal between the shaft and the shoulder of the rivet. After some hammering and prying I could begin to see the seam and was able to separate the rivet shoulder from the shaft. Once that was done, I used a grinding stone on the Dremel to remove some metal on the shaft ends to allow the other parts to slide off of the shaft.
On reinstallation, I did not reinstall two spacers that were originally on the shaft, just inside the seat frame. Without these, the end sleeves were just about the perfect length - not too long as was described in the video. After waiting for the epoxy to cure for the gears, I started the reassembly and then had to wait a few hours again for the epoxy to set on the end sleeves. So, it takes some time and patience.
Initially, the job was a little intimidating but after spending time with it - it wasn't too bad. Maybe it would have been easier had I removed the bottom seat cushion. I just noticed that the directions said to do that. :)

Happy with my purchase.

The part was as described. It was made of quality material and was the perfect fit. It even arrived sooner than expected.
The only thing missing was a picture of the kit to give us reassurance we were ordering the right product. But no worries, it was the right part.

Great product. Documentation could be improved.
Posted by Nick on 23rd Jun 2022
My driver's seat stopped moving forward/backwards after 230,000 miles and 15 years on my 2007 Suburban and I looked to the forums for solutions. I was planning to go buy a junkyard seat, but then found a link this kit on a forum. This kit solves a niche problem: GM's low quality plastic gears that break inside their seat forward/backward adjustment.
The gears are great quality and fit in perfectly with the other parts. $70 seemed pricey at first for 4 pieces of metal, but it solves a problem that would otherwise require an entirely new seat unit, so this kit is well worth the price.
Thank you Paul for designing these-- I'm sure you've saved many people huge amounts of money by avoiding buying an entire replacement seat unit.
However, given this premium price, it would be nice to have better documentation. The video and the printed instructions are both missing small steps. Not a huge deal, and I eventually figured everything out, but I had to go back and forth between both the written instructions and video at the same time to understand exactly what to do. Had the instruction set been complete, I could have likely completed this repair in an hour less time. Paul, if you ever happen to do this repair again, I'd love to see a new, more detailed video. Thank you!
