*Stock pistons in 2007 and later engines require rods with tapered wristpin ends. Note: All S&S Flywheels for 2007 and later engines have 7.659” length connecting rods (except the SE120R & S&S 143, see chart). **Note: Flywheel assemblies supplied with sprocket shaft bearing race installed are compatible with stock roller style sprocket shaft bearings. Assemblies with no race require a Timken® sprocket shaft bearing. ***41/2" stroke flywheels include 7.667" long connecting rods.

† These flywheels are replacement flywheels for the SE 120R. When installing these flywheels in a Harley-Davidson® case, they need to run the HD piston oiling jets— not the S&S® piston oiling jets. Strokes longer than stock will require S&S Piston Oiler Set, part #31-2026. 2007–up stock rod length is 7.659". Main Bearing Note: Most S&S flywheel assemblies for 1999–'17 big twin engines are designed for use with Timken® sprocket shaft bearings. They will fit directly in stock 1999–’02 Harley-Davidson® crankcases and in all S&S crankcases for 1999-'17 big twin engines, with no modifications. However, stock 2003 and later engines use a roller type bearing for the sprocket shaft. S&S does offer flywheel assemblies that are compatible with late roller style stock sprocket shaft bearings, but they are not recommended for very large, high performance engines. S&S strongly recommends retrofitting 2003–'16 model crankcases to accept a Timken sprocket shaft bearing. A Timken conversion sleeve such as Screamin' Eagle® #34822-08 or Jim's® #956 may be used. A charging system spacer for 1999–'02 model year is also required. If you choose not to convert your crankcases to a Timken sprocket shaft bearing, S&S flywheels may be used in 2003 and later engines by either purchasing the stock compatible flywheels or by installing Harley-Davidson® bearing kit #24004-03B when using S&S flywheels designed for Timken bearings. This bearing kit adapts the S&S sprocket shaft so it is compatible with stock roller type bearings. Verify that the bearing kit contains the 24604-00D or 24607-07 sprocket shaft bearing. Do not use a 24604-00, 24604-00A, 24604-00B or 24604-00C bearing. Please be advised that if this type of bearing is used, sprocket shaft bearing failureWILL NOT be covered under warranty.
