mountune ARP Ford Crossflow/Lotus Twin Cam Main Stud Kit

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.
  • Made in the USA
  • ARP Premium 8740 steel
  • 12 Point Nuts
  • Hardened Washers

Application:

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


PRELOAD (TORQUE) RECOMMENDATIONS:

Following the manufacturer's recommended torque sequence tighten the nuts in three equal steps to 80 lb-ft with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. ARP recommends using the ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to engine oil. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when engine oil or other low-quality lubricants are used.
