Polaris RZR Pinion Shaft and Snorkel Gear Kit

Pinion Shaft and Snorkel Gear Kit for the Polaris RZR

Upgrade the pinion shaft and snorkel gear in your Polaris RZR transmission with a heavy-duty matched set. These components are the primary torque-transfer path between the engine and the front differential, and this kit replaces the factory parts with stronger materials and improved geometry.

Upgraded Pinion Shaft
The pinion shaft in this kit is machined from high-strength gear steel and heat-treated for maximum surface hardness. The upgraded material handles the higher torque loads generated by engine tunes, clutch kits, and larger tires — loads that exceed what the factory shaft was designed for.

Reinforced Snorkel Gear
The snorkel gear is cut from the same high-strength steel as the pinion shaft, with optimized tooth geometry for smoother engagement and more even load distribution. The reinforced tooth profile resists the pitting and chipping that cause stock gears to fail under sustained high-torque operation.

Matched Set
The pinion shaft and snorkel gear are manufactured and inspected as a matched pair. Running a matched set ensures proper gear mesh from the first engagement, eliminating the break-in noise and accelerated wear that come from pairing new and worn components.

Direct Replacement
This pinion shaft and snorkel gear kit is a direct replacement for the factory components in the Polaris RZR transmission. Spline count, shaft diameter, and gear dimensions match the original specifications for a drop-in installation with no case modifications required.
