BMC Triumph 2.0L Single Overhead Cam TR7 with 2 Bolt mains, There are many important reasons to use ARP main stud kits, including the elimination of main cap walk and fretting, as well as protecting the threads in your engine block. The ARP 2 Bolt Main Stud Kits are manufactured in ARP's own factory using the best materials, processes, designs and engineering.

Every ARP 2 Bolt Main Stud Kit exceeds the most stringent aerospace specifications. All kits come complete with hardened parallel-ground washers and aerospace quality nuts. Some applications have provisions for mounting windage trays and have specially designed standoff studs with serrated lock nuts to position the windage tray and lock it securely in place.

The ARP 2 Bolt Main Stud Kits are manufactured from 8740 chrome moly steel, heat-treated in-house to 200,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others.

Don’t settle for anything less than the best. Insist on genuine ARP studs – you’ll find the ARP name stamped right on the end!

Parallel-ground, hardened washers are included with each kit.

STUDS vs. BOLTS

ARP recommends the use of ARP 2 Bolt Main Stud Kits over bolts whenever possible for several key reasons. First is the ability to obtain more accurate torque readings because studs don’t “twist” into the block. All clamping forces are on one axis.

By the same token, there is less force exerted on the block threads, which contributes to improved block life (very critical on aluminum blocks). Finally, there are factors of easier engine assembly and proper alignment of caps every time.
