GruvenParts Upgraded Lumbar Support Parts for Schukra Units (07-24 Sierra 2500 HD)

Description. GruvenParts is happy to announce our fix for the Schukra 2016901 and 2016902 electric motor driven lumbar support mechanisms prevalent in many GM, Ford, Honda, Acura and many other makes utilizing the actuator shown with electric cable driven lumbar support mechanisms (not for pneumatic lumbar mechanisms). A growing list of Schukra part numbers these fit in is shown below. Please note we dont have the dual cable wheels (yet).

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.
