SuperATV Complete Differential
SKU: DIFF-1-004-K
Moderate — 2–4 hours
Overview
Constructed with a heavy-duty cast or billet aluminum case, this differential features hob-cut ring and pinion gears for smoother operation and longevity. The Sprague carrier is made from 7075-T6 aircraft-grade aluminum for maximum strength during frequent differential lock engagements. Enhanced mounting locations with helical inserts and additional material prevent bolt wallowing, while a thickened pinion gear tube ensures it can withstand torque loads. A bolt-on pinion bearing cap simplifies servicing.
