Description

Manufactured from 8740 chrome moly steel, these studs are heat-treated to 190,000 psi tensile strength and feature precision J-form threads rolled after heat-treat for superior durability.

ARP recommends using main studs over bolts for more accurate torque readings, as studs do not twist into the block and apply clamping force on a single axis. This also reduces stress on block threads, improving block life, especially in aluminum blocks, and facilitates easier engine assembly with proper cap alignment.
