FITS ALL POLARIS RZR/SPORTSMAN/RANGER 700 and 800 MODELS. Case hardened heavy duty Titanium head studs. Allen head drive for easier install. Using a stud/nut instead of the OEM bolt creates a better seal, enables you to torque your head down tighter, and resists shearing, which is usually what causes head bolts to fail.
We recommend that this be installed by a qualified mechanic with experience doing this type of work.
