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. This makes for a great looking set of rods, and increases strength by maintaining a uniform material thickness around the wristpin. The machining process also keeps the difference between the small end weights of each rod to a minimum - allowing for the closest possible balancing job and a smoother running engine. Features an alloy bearing cage. Stock length and can be used for stock replacement for 1986 - 1999 Harley-Davidson® Sportster® models. .792" wristpin, 6.926" rod length.
