ARP recommends the use of main studs 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. Finally, the there are factors of easier engine assembly and proper alignment of caps every time. Add strength to your bottom end by upgrading your main cap bolts to ARP studs. Main cap studs are the perfect addition to engine builds receiving Billet Main Caps.
