SuperATV Complete Heavy-Duty Transmission
SKU: TRAN-P-GEN1K-K203XP
Professional / shop required
Overview
This transmission boasts a 2.5x stronger overall construction compared to stock, with a reverse chain that is 2x stronger. Key components like the pinion shaft and gears are made from 9310 heavy-duty steel, and the front output shaft is constructed from 300M alloy steel for enhanced durability. The transmission case is reinforced with 68% more material, particularly around axle outputs and the snorkel tube, and includes extra ribs and gussets for improved strength and cooling. The gears are lapped for smoother operation and reduced wear. Options for gear reduction (12.5%, 25%, 37.5%) and the deletion of turf mode are available to further enhance performance and durability.
