8 CYL MOPAR 340 360 BULLET ROD CHEVY 2.1 CRANK .927 PIN 6.125 7 16 BOLT

Carrillo connecting rods are made from a proprietary alloy, forged, and fully machined. They undergo heat treatment, magnaflux inspection, hardness checks, and are then machined to final size. Each set is balanced and shot-peened for strength and fatigue properties. This set includes Carrillo H11 tool steel (WMC) bolts, which are high-quality, aircraft-standard fasteners with asymmetrical threads for even clamp load distribution and increased fatigue life. These Pro-H style rods are designed for Porsche 964 RSR engines with 127 mm rods and 23 mm pins and are not compatible with factory OEM pistons.
