SuperATV Heavy-Duty Front Differential Gear Case
SKU: DIFF-1-003791
Advanced — 4+ hours
Overview
This complete differential assembly includes a heavy-duty cast or billet aluminum case, thicker gears, bushings, seals, hubs, Sprague carrier, armature, and wiring. The Sprague carrier is constructed from 7075-T6 aircraft-grade aluminum for maximum strength and durability, ensuring it can withstand frequent differential lock engagements.
SuperATV has reinforced the mounting locations with helical inserts to prevent bolt wallowing and added material for a more secure mount. The pinion gear tube is also thickened for increased durability, and a bolt-on cap allows for pinion gear service without damaging the seal.
