Brian Crower Head Stud Kit ARP Custom Age 625+ For Yamaha YXZ1000R 16+ Arctic Cat XX 18+

Made from ARP625+ Custom Age material and rated to 280,000 psi, ARP cylinder head studs not only offer superior clamp loads over cylinder head bolts, they provide proper alignment of the head and gasket with more accurate and consistent torque loading. Bolts will actually twist while torquing to proper spec, greatly reducing their ability to hold true.
