Upgraded Lumbar Support Parts for Schukra Units

Product Description

** Our METAL gears and high strength cable drive wheels are guaranteed for life !! **

GruvenParts is happy to announce our fix for the Schukra 2016902 electric motor driven lumbar support mechanisms prevalent in many GM and Ford vehicles and many other makes utilizing the actuator shown with electric cable driven lumbar support mechanisms (not for pneumatic lumbar mechanisms).   

We have produced upgraded SOLID BRASS pinion gears as well as high strength polymer cable drive wheels for both the drivers and passenger front seat lumbar support mechanisms found on most GM (and other makes) from 2000-present with the Schukra 2016902 electric cable driven lumbar adjustment unit.  Check part numbers below and pictures on this page to verify fitment on your vehicle. 

The OEM Schukra lumbar support mechanism contains a plastic planetary gearing system which moves the lumbar support cushion within the seat.  The three small plastic pinion gears within the Schukra lumbar support mechanism usually shatter and render the unit useless.  The lumbar cable drive wheel also typically fails in this Schukra unit as well.  A replacement unit from GM is expensive and will also soon fail due to these weak parts.

Dont buy an expensive new OEM unit when you can FIX AND UPGRADE your existing Schukra 2016902 unit using high strength parts ! 

Choose your option from the drop down menu and buy as a kit and save  :

- Pinion gear kit only made from solid brass and contains (3) three brass pinion gears which mount to lumbar cable drive wheel.  Sold in sets of 3, enough to fix 1 lumbar unit.

- Lumbar drive wheel made from high strength polymer. Sold individually, enough to fix 1 lumbar unit.  

- Kit of 3 solid brass pinion gears and 1 high strength polymer lumbar drive wheel, enough to fix 1 lumbar unit

- 2 kits of 3 solid brass pinion gears and 1 high strength polymer lumbar drive wheel, enough to fix 2 lumbar units (1 complete seat) 


*** Save $ buying the kit sets ! Please note, there are normally 2 Schukra 2016902 lumbar drive units per seat so if you wanted to fix both, you would need 2 kits. Please verify your specific application needs prior to ordering. 


*** These parts will fit in any SCHUKRA P/N 2016902 electric cable driven lumbar unit regardless of the year/make/model of the vehicle.  They have likely used this electric lumbar support adjuster in many different vehicles, not just GM.  Schukra also probably has many other part numbers for their units using these same parts as well, we will continually add to this page as more info comes in.


Applications :

This brass pinion gear set and high strength polymer lumbar wheel replaces the 3 small plastic pinion gears and plastic lumbar wheel in the Schukra 2016902  and GM lumbar unit P/N 19-12-71-56 (19127156), 88-94-02-95 (88940295), 88-97-83-50 (88978360), 22-83-30-14 (22833014) 2016902 as well as likely many others.  The Schukra P/N  is 2016902 and 5030024A (for Nissan) (as well as many others) for the drivers and passenger side electric front seat power lumbar support assembly.  These parts are also common to Ford P/N AR3Z-6365500-B on the 2005-2014 Mustang.  This part number list will be continually updated as we learn of more lumbar support assemblies also using these Schukra parts.

The estimated models using this lumbar support assembly are all GM vehicles from 2000 to present, as well as many Ford vehicles including Mustang from 2005-2014 however we ask that you check your OEM part number and look at the pictures closely to see if your mechanism looks similar.  If it differs from that listed above or is a pneumatic rather than cable driven electric lumbar, contact us and we can research and confirm fitment as we build the part number cross reference matrix.

We're also working on the DIY for this, however once the lumbar unit is removed from the seat back, its a matter of removing a few screws to separate the case halves and then removing/replacing the 3 small plastic pinion gears with the upgraded solid brass gears as well as the lumbar drive wheel.

    It's about time that a company came up with a permanent fix for a common problem. This is it! 1/3 the cost of a new power lumbar assembly. Way to go Gruven parts! Thank you

  2. Electric lumbar support fix 5 Star Review

    Posted by on 16th Jun 2022

    My 07 Chey silverado ltz made with cheap plastic part all over and most have broken !
    Electric seat back and forth gears broke and fixed with Gruven gears. Lumbar support partially fixed. Both the up and down and in and out motions didn't work.
    Fixed the up and down motion but the gears and just about all plastic inside the gear box were broken and couldn't be repaired.

  6. Great price for best repair parts. 5 Star Review

    Posted by on 15th Dec 2021

    The best price for replacement parts was twice the price of the gear kit to repair.
    And theses gears will last 10X longer than the factory ones.

  7. Expensive but finally fixed my problem 4 Star Review

    Posted by on 3rd Jul 2021

    I replaced the plastic gears once with plastic gears from the junk yard and they broke on the first drive! I wished someone made metal replacement gears. I found Gruvenparts from a youtube video on Chevy truck side mirrors and luckily they make these gears too. Worked perfectly. How about a video on this repair too? The side mirror video is excellent.
