- Heat-treated 4140 material: harder and more than twice as strong as stock - Stronger fitment eliminates the need to weld the crankcase pinion nut - S&S high-strength connecting rods are designed using finite element analysis to eliminate weak points - Full-width connecting rods for wrist pin (requires S&S high-performance pistons) - Balanced for S&S high-performance piston weight (1213 g) - Ideal for gear-driven camshafts - Consistent balance and precision machining - Capable of reaching higher RPM for more available power
Note: Required for the installation of the 131" big bore cylinder and piston kits 923194 / 923193 (4.250" bore) and S&&S 994438/994437 136" (4.320" bore).
