They are manufactured from a two-piece forging of SAE 4340 steel with features including .927” silicon bronze bushings for floating piston pins, 230,000 psi rated ARP 2000 3/8” cap screw rod bolts and cap alignment sleeves for precise, positive cap location. The rods are weight matched to plus or minus 1 gram and the housing bore sizing is performed on a precision Sunnen grinding system for perfection!  These are 5.700 length.
