Brand: Automotive Racing Products (ARP)
Replace your main bearing cap bolts with high-strength ARP main studs for improved engine life under the most demanding racing conditions!
Main studs locate the main bearing caps more securely than bolts alone, which means less tendency for the caps to walk and fret the mating surfaces. Studs also provide more accurate and consistent clamping force because the fastener does not twist when you apply your torque wrench. Studs only get installed once (rather than at every rebuild), which reduces the chances of damage to the female threads in the block.
ARP main studs are made from 8740 chrome moly steel, heat-treated to 200,000 psi tensile strength with J-form threads that are rolled (not cut) after heat treatment (not before) for unmatched strength and precision.
This set fits 1991 and later Ford 4.6L and 5.4L Modular V8 engines with 2-bolt main caps and no windage tray. Includes ten M10 main studs (including one extended stud for oil pickup tube mounting), matching hardened washers and nuts, and a packet of ARP assembly lube.
Note: Because of the wide range of applications, cross bolts are sold separately:
