One of the secondary operations incorporates fractured cap technology.

This procedure eliminates fretting, which is undesirable cap movement, and makes alignment sleeves unnecessary. A fractured cap also provides superior alignment of the cap to the body each and every time. This provides a much better crank bore roundness versus machine caps after assembly. We then use Ampco bushings and 3/8” ARP 2000 capscrews. The results are rods that are easily resizable by simply honing out the crank bore and using oversize o.d. bearings.
