Crower has been making top-end, high performance connecting rods & crankshafts for more than 25 years. We have the experience and state-of-the-art technology to build some of the highest quality and most reliable rods & crankshafts on the market.

Our steel billet connecting rods feature only the finest USA-made proprietory steel, which is CNC-machined to remove all surface imperfections. They are 100 percent magnaflux-inspected, checked for surface hardness, and then machined to final size to exacting tolerances within 1/1,000 of an inch. Each set of rods is fully balanced and then shot-peened to achieve the ultimate in strength and durability. Other features include: Drilled and chamfered wrist-pin oil holes on each rod for additional oiling, to prevent galling; deep, double-ribbed caps for superior strength at high rpm; and a hollow-dowel alignment fastening system for positive cap alignment. The rods are available in I-beam models with either premium H-11 tool-steel rod bolts (7/16; 220,000 psi) or AMS5844 (7/16; 280,000 psi) bolts as upgrades. They can also be ordered with a special, pressure-fed oiling hole from the big end to the pin end of each rod, for pressurized wrist-pin oiling. Custom Lengths also available and fully machined in San Diego.

Crower Crankshafts are made from the finest quality materials in the world. Our top of the line forged cranks are made from aerospace quality, vacuum degassed 4340 chromoly steel. Our 4340 forged cranks are "non-twist" drop forged for the strongest crankshafts on the market. Crower's billet cranks utilize either 4340 or EN30B materials. It's your choice at Crower, we make what you want and need for your application.
