Brian Crower Polaris XP Turbo (16-up) / XP 1000 (14-up) ARP Case Stud Kit AR8790

***NOTE: Must have linebored main journals and oversize King main bearings (BC4900) to use these case studs otherwise housing bore distortion will occur and crankshaft will not rotate.***

If using on a stock RZR crankcase, recommend AR8791 case bolts.

Made from ARP2000 material and rated to 220,000 psi, ARP case stud kits not only offer superior clamp loads over stock, torque to yield case bolts, they provide proper alignment of the both case halves with more accurate and consistent torque loading. Bolts will actually twist while torqueing to proper spec, greatly reducing their ability to hold true.
