Overview

The SuperATV Heavy-Duty Front Differential Gear Case is engineered to replace the stock differential housing for Polaris General and General 4-seater models. Constructed from 6061 aluminum in either cast or billet options, it features steel helical inserts for reinforced mounting points. This gear case comes with the magnet and wiring pre-installed, along with all seals and bushings, simplifying installation. It utilizes a bolt-on cap for pinion bearing retention, foregoing the need for a snap ring. The housing does not include internal gears, allowing for the direct use of stock internal components.
