WSRD Ultimate HD Head Stud Kit | Can-Am X3 (Rated to 550HP)

The ARP Custom Aged 625+ Head Stud Kit is a 9mm head stud that replaces the factory head bolt. 

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 torqueing to proper spec, greatly reducing their ability to hold true.
