Mountune ARP Main Stud Kit, Ford Crossflow / Lotus Twin Cam

Application: Ford Kent blocks with later square caps (691M, 711M, 701M, 821M and 771M) or early blocks with square steel main cap conversion.

Our ARP Main Stud Kit helps to eliminate main cap walk and fretting, as well as protecting the threads in your engine block. All kits come complete with hardened parallel-ground washers and high quality nuts. The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat treatment to create a fastener that has threads 2000% stronger than others. This is a must for racing and high performance engines.
