S&S CYCLE Connecting Rod Assembly - XL 34-7800

If you're building a big-displacement stroker motor or running sustained high RPM loads, stock connecting rods become a weak link. The S&S CYCLE XL 34-7800 rod set eliminates this vulnerability with deep-forged, heat-treated construction designed to handle the abuse of forced induction and extended stroke applications. This is a complete, ready-to-install assembly—no hunting for individual components or worrying about rod-to-rod compatibility.

The engineering here reflects decades of Harley-Davidson performance development. The rods are 0.120" wider in the I-beam section than OEM pieces, providing the structural rigidity needed for strokes up to 5 inches. Oil delivery is optimized with precision-ground slots and dual holes in the crankpin, ensuring consistent film strength under extreme loads. You get two complete rod sets (front and rear) with all hardware, bearings, and cages included—installation is straightforward, though you may need to clearance your flywheels and cases depending on your specific build.
