Connecting rods

Connecting rods are manufactured by Revmaster, forged of 4340 alloy steel with 9mm bolts. The bolt and cap design allows for ample clearance of the rotating parts due to the increased stroke of the crankshaft. 137mm cente-to-center rods are available for the R-2100 and R-2200 series engines. The R-2300 uses 142mm center-to-center and the big end is configured for 2″ Chevy journal.
