ARP Main Stud Kits — Stronger Bottom End, No Cap Walk

ARP main stud kits stop main cap walk and thread fretting in your block — the two failures that wreck a high-performance build.

Every ARP kit is built around ARP 8740 chromoly studs, heat-treated in-house to a 190,000 psi tensile rating. Threads are rolled after heat-treat, not cut — that's what gives ARP fasteners measurably higher fatigue life than budget studs with threads cut before treatment.

Each ARP Studs kit is application-specific and is complete with:

• ARP 8740 chromoly main studs
• Hardened, parallel-ground washers (even clamp load, no galling)
• Premium 12-point or hex nuts
• ARP Ultra-Torque assembly lube

Australian stock. Same-day dispatch on in-stock kits.
