Instructions

S&S Heavy Duty connecting rod sets for Harley-Davidson® Sportster® models are recommended for stock rebuilds and most performance street applications. They have stock wristpin width for use with stock bore pistons. S&S Supreme connecting rods are recommended for the most demanding applications including nitro engines. S&S Supreme rods have big twin width wristpin ends and are intended for engines with bore size larger than 3 5/16".

Features and Benefits:

  • Thicker I-beam sections for added strength
  • Heavy Duty rods are forged from 4140 chromoly steel
  • Supreme rods are forged from 4340 EQ, aircraft quality chromoly steel
  • Heat treated to provide superior strength, hardness, and fatigue resistance
  • S&S crankpins have two oil distribution holes located between the roller bearing paths for better oil distribution and continuous, unbroken support to the bearing
  • Grooved thrust faces on crankpin end of rear rod help maintain lubrication between the rod and flywheel thrust face
  • Rod-to-rod clearance accommodates strokes up to and including 5" stroke
