670 S&S® Heavy Duty connecting rods Great connecting rods just got better! We revised the design and added material to the piston wrist pin area of our forgings to achieve two very important benefits. The upper rod area where the rod beam meets the wrist pin boss has been blended together with a large, smooth radius that evenly distributes the stress load on the rod, and the small ends of the rods are now fully machined. S&S® Supreme connecting rods Supreme rods offer tremendous strength for racing and other demanding applications. Big Twins® Connecting Rod Selection Chart Bearing Cage Type: Steel Type diameter Length 53-1208 Heavy Duty .927” 3 7.668” 3: Twin Cam piston use .927” wrist pins (1999-up). Sportster style Connecting Rod Selection Chart Bearing Cage Type: Alloy This makes for a great looking set of rods, and allows us to increase strength by maintaining a uniform material thickness around the wrist pin. The machining process also keeps the difference between the small end weight to a minimum allowing for the closest possible balancing job and a smoother running engine.
