For those running high HP levels that need more clamping force and tensile strength than the typical ARP 8740 chromoly studs on the market. If you are looking for the best option, these are 25% stronger than standard ARP VR6 main stud kit.
When main studs stretch, the crank begins to walk away from the bearings, main bearing clearance increases and oil pressure is reduced, rod bearings don’t like that!
VR6 engines have qty 20 head studs vs. qty 14 mains studs. With the 12v those are (20) 11mm head studs vrs the (14) 10mm main studs as they both share the same loads while engine making power.
