ARP 247-4202-98.5-18 5.9/6.7 CUMMINS

Produced to Mil-S-8879 specifications, ARP cylinder head stud kits are centerless-ground and thread-rolled with a black oxide finish for durability and corrosion resistance. ARP also includes hardened parallel washers for even load distribution and reliable torque readings.

To help prevent head gasket failures with increased boost pressure from performance parts we highly recommend installing a set of ARP head studs.
