ARP main studs eliminate main cap walk, as well as protect the threads of the block. ARP recommends to use main studs over main bolts whenever possible. Studs provide a more accurate torque reading because they don't twist in the block as they are torqued down. All clamping forces are on one axis. There is also less force exerted on the block threads which improves the engine block's life, especially on aluminum blocks. Finally, studs allow for proper alignment of the main caps and easier engine assembly.
