Years ago, and still to this day, Chris, Ninja Performance, was pushing the 6G72 DOHC 2 bolt TT block past its limit. Pushing the crank off the block, literally pushing the vertical girdle stay bracket bolts out of the block.
He would find the vertical girdle stay bracket bolts in the oil pan, with the threads totally laid flat.
He would find the girdle stays destroyed with severe wear and score marks from where the crank was being pushed off the block, pushing the entire girdle down away from the block with the stays attached to it. This constant bouncing and movement meant the stays were constantly being lifted away then slammed back onto the block.

This was occurring around 700AWTQ. He tried many fixes and through lengthy trial and error and rebuilds, more testing, and lots of track runs, he came up with this kit.

This kit will allow you to push beyond that 700AWTQ stock fastener limits of the 6G72 2 bolt block.

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 studs are manufactured in our own factory using the best materials, processes, designs and engineering. Every ARP? main stud kit exceeds the most stringent aerospace specifications. All kits come complete with hardened parallel-ground washers and aerospace quality nuts. The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 220,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others. Do not settle for anything less than the best. Insist on genuine ARP studs kits.

Install Instructions:
* Studs go into block finger tight. Do NOT fully install/bottom out the ARP Studs int the block. Leave the ARP Studs backed out far enough to allow the ARP Stud's threads to reach out beyond the girdle far enough to allow for installation of supplied ARP washer and ARP 12 point nut.

* Use the supplied ARP Ultra-Torque Lube on ARP Stud threads and on both faces of the ARP washers. Failing to apply the ARP Ultra-Torque on threads and both washer faces, top an bottom, will result in friction and cause improper torque readings due to this friction.

*Tighten nuts in 3 steps - 30/60/90 ft/lb. Following Mitsubishi's recommendations for torque sequence.

Fits:
