Series 9000 cast crankshafts. The next step towards making big, reliable power for street or strip use. Our 9000 series crankshaft comes in a wide range of strokes & rod combinations. Budget minded, performance driven. Designed & engineered at SCAT, Precision ground & micro polished and IMCA & Race Saver approved.


Forged from 5140 steel for outstanding strength and reliability and they come in both press-fit and bushed pin models. Their lightweight design places less stress on the rest of your rotating assembly to increase engine life and better handle high-rpm use. The rods are X-rayed, sonic-tested, magnafluxed, and shot-peened to stress-relieve the metal. They come with 12-point ARP Wave-Loc rod bolts (3/8 on small block 7/16 on big block) and are weight-matched to within two grams. The big end sizing is controlled by in-house CNC equipment to ensure precise machining and accurate fitment. Perfect choice for Small Block engines producing up to 500 horsepower.


Small Block Mopar Street/Strip Diamond Pistons are designed to fit most OEM open and closed chamber heads and will work with aftermarket Edelbrock & Indy heads.

H series rod bearings have a medium level of eccentricity, high crush and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating.

P-Series main bearings are the oldest members of the Clevite 77 bearing family and are intended for high-revving engines. To compensate for the high-load factors and distortion in these engines, these bearings have higher eccentricity and a high crush factor. P-Series bearings are built on steel backings with extra-thin overlays to prevent overlay fatigue. In addition, the oil grooves on most applications extend all the way around both halves for better oiling.
