Ring and pinion Jeep Wrangler JL

Reinforced front ring and pinion for Jeep Wrangler JL produced from 2018.

They are made of SAE8620 steel with the Gleason process, are subsequently thermally hardened to resist wear and surface treated with black oxidation to make them extremely silent.

They are produced in the U.S.A.  by the well-known Motive Gear company that for years has been producing components for the transmissions of American vehicles and Ultra4 vehicles.

The high construction precision makes the recording particularly simple, however we recommend having the installation carried out by a specialized workshop. In the Download section you will find the assembly instructions.

The main installation features are the following:

  • differential case design type: M210
  • ring gear bolt quantity: 10
