Heads up

Polaris PRO-R Diff Race Prep for serious racers. Stock Polaris PRO-R differentials are mass produced. Stock gears can crack and wear prematurely. While the factory assembly procedures work for basic end users, those procedures are not always sufficient for the shock loading these units are subjected to in a racing environment.

Decades of Weddle Industries experience goes into every service. Weddle Industries specializes in the hardest working gearboxes in the world. We put our knowledge and experience into every Weddle Race Prepped Pro-R gearbox to maximize gear life and ensure each gearbox operates at its highest level.
