Product Details

S&S heavy duty connecting rods are recommended for stock rebuilds and high performance street engines. The upper rod area where the rod beam meets the wristpin boss is blended together with a large, smooth radius that evenly distributes the stress load on the rod, and the small ends of the rods are fully machined for increased strength and uniform material thickness around the wristpin. The machining process also keeps the weight difference between the small end weights of each rod to a minimum, allowing for the closest possible balancing job and a smoother running engine.

These connecting rod assemblies are more than tough. Replaceable lower bearing races, a better oiling crankpin, and additional rod-to-rod clearance create perfect conditions for a big bore kit or longer stroke flywheels.

Features and Benefits:

Heat treated to provide superior strength, hardness, and fatigue resistance
Heavy duty rods are forged from 4140 chromoly steel
Bearing clearance is pre-fit so rods come ready to install
Crankpins have two oil distribution holes located between the roller bearing paths for continuous oil distribution to the bearing
Thrust faces on crankpin end of rear rod are grooved to distribute oil and help maintain lubrication between the rod and flywheel thrust face
Designed with additional rod-to-rod clearance to accommodate strokes up to and including 5"
Rod length: 7.440"
Wristpin diameter: .791"
Bearing cage type: iron

NOTE: Fits Evolution engines only.
