24275-86A Heavy-duty Connecting Rods

S&S Heavy-Duty connecting rods are the gold standard for street performance builds. These rods feature a revised design with extra material around the wrist pin area and a large, smooth radius to distribute stress more evenly. The small ends are fully machined to maintain uniform thickness and minimize weight differences between the rods, which makes for a much smoother running engine once balanced. This set replaces OEM 24275-86A and fits 1986–1999 Sportsters and 1994–2002 Buell models, as well as 1941–1999 Big Twins. Sold as a set including front and rear rods, steel cages, and a crank pin, they are built to handle serious power.
