EPI Performance Polaris Jam Nut Driver
Service the primary clutch on your Polaris UTV or older model RZR/Ranger with the specialized, heavy-duty EPI Performance Jam Nut Driver #338. This robust tool is precision-engineered for a secure fit on the primary clutch jam nut, which locks the clutch spider in place. The 3/4-inch square drive allows for maximum torque application using a breaker bar or impact gun, ensuring you can break loose even the most stubborn, factory-torqued nuts.
The #338 driver is an indispensable accessory for any garage performing clutch modifications, maintenance, or repair on compatible Polaris UTVs and ATVs. It ensures that critical components are not damaged during disassembly, leading to accurate reassembly and optimal clutch performance. Please check the compatibility note below, as many newer Polaris UTV models (including RZR 1000s and newer 900-class machines) require the EPI #578 driver instead.
