Specifications

Why fit main studs

The ARP B18C Main Studs kit helps stop main cap walk and fretting at high rpm and boost, and it protects the threads in the engine block because the studs are not turned in and out each time the caps are torqued.

How they are made

Each stud in the ARP B18C Main Studs kit is made from 8740 chrome moly steel, heat-treated in-house to 190,000 psi tensile strength, with precision J-form threads rolled after heat-treat. ARP rates these threads as 2000% stronger than others.

Fitting

Main studs are fitted with the engine apart. Clean the block threads, fit the ARP B18C Main Studs studs finger tight, fit the caps, and torque the nuts in steps using ARP Ultra-Torque lubricant as the kit instructions describe. Check the main bearing clearances after fitting, as the clamp load can differ from the factory bolts.

This main stud kit is often fitted alongside ARP head studs and rod bolts when building a strong bottom end.
