Power Dynamix is now offering Billet Main Caps for sale.

Why use our caps? Because our caps have a perfect and tight press fit into the block registers. We have seen too many other brand caps with a loose fit straight out of the box. This will absolutely cause main bearing failure when the caps flex under high power situations. As a machine shop we see way too many "bad caps" and we decided to make our own version of caps to eliminate this problem once and for all. Our caps also require minimum stock removal when line boring the block. This will save the machine shop time and thus translates into saving you money in machining costs.

We also offer 2JZ block line boring/line honing services to fit these caps to your block.
