The upper rod area where the rod beam meets the wristpin boss is blendedtogether with a large, smooth radius that evenly distributes the stress load on the rod, and thesmall ends of the rods are fully machined for increased strength and uniform material thicknessaround the wristpin. The machining process also keeps the weight difference between the smallend weights of each rod to a minimum – allowing for the closest possible balancing job and asmoother running engine.Supreme Connecting RodsOriginally developed for nitro burning engines. Supreme rods offer tremendous strength forracing and other demanding applications.KIT CONTENTS• Nuts (if required)• Front and rear connecting rods• Crankpin with end plugs• Bearings and retainersS&S® CONNECTING RODSYear Rod Type Bearing Cage Type Wristpin Diameter Rod Length Part No.1984-'99Note: All pistons for 1984-'99 big twin engines use .792" wristpinsNOTES34-7214This special connecting rods set contains a stock style stepped crankpin for use withstock 1936-’52 OHV flywheels.S&S rods with their beefier than stock construction are slightly heavierthan stock connecting rods. Therefore, rebalancing the flywheels isrecommended when S&S rods are used in stock replacement applications.We realize that rebalancing is an inconvenience, but we did not wantto sacrifice rod strength. In addition, given the variations in stockand aftermarket components available to engine builders, flywheelrebalancing is a desirable step in any major engine overhaul.To aid shops and engine builders perform the rebalancing procedure, S&Shas developed and offers a complete flywheel rebalancing kit.
