Sandcraft Motorsports Polaris RZR Pro R PTL Lock Nut w/ Set Screw
The Sandcraft Motorsports PTL Lock Nut with Set Screw might just be the single most important hardware upgrade you can make to your Polaris RZR Pro R. This critical nut is responsible for setting the compression for the clutch pack located between your driveline and transmission. The factory OE lock nut relies on a simple 'punch' at the set groove to stay in place, a design that has shown a high rate of failure under off-road stress.
When the factory detent fails, the nut loosens and releases tension on the clutch pack, resulting in a complete disengagement of your 4WD system and potentially severe damage to the clutch pack itself. In some cases, the loosening causes a slipping engagement in the front wheels that goes unnoticed until the damage is already done. Sandcraft solves this catastrophic issue with a heavy-duty, 4142 pre-heat-treated stainless steel lock nut. This upgraded nut utilizes a true mechanical set screw to lock it firmly into position, featuring three distinct set screw locations to simplify hitting your critical torque specs perfectly.
Features
- Prevents 4WD Failure: Positively locks the clutch pack compression, preventing the nut from backing off and causing a sudden loss of 4-wheel drive
- Protects Vital Components: Eliminates clutch pack slipping and prevents the severe internal damage caused by factory lock nut failure
- Heavy-Duty Construction: Expertly CNC-machined from ultra-strong, 4142 pre-heat-treated stainless steel for uncompromising strength
- Mechanical Lock System: Replaces the unreliable factory "punch" detent with a secure, mechanical set screw to guarantee the nut stays exactly where you put it
- Easy Alignment: The nut body features 3 distinct set screw locations, making it significantly easier to align the screw while hitting the strict 85-90 ft. lbs. torque spec
Fitment
- Polaris RZR Pro R
Notes
- Torque this nut to 85-90 ft. lbs. to properly align the set screw. Due to the critical nature of this component within the transmission/driveline, professional installation is highly recommended
