S&S, 4-1/2" stroke flywheel kit for years 06-17

For 106" long stroke engine. S&S connecting rods do not have tapered crankpin ends and are not compatible with stock H-D pistons or stock H-D sprocket shaft bearings. Balanced to a total piston weight of 1108 grams.
Note: Engines with strokes over 4" may require S&S piston oil jets and clearance notches between piston and jet in the piston skirt to avoid contact.
Note: S&S crankpins allow the use of replaceable bearing bushes in the lower end of the connecting rods. The first generation of S&S crankpins, in use until 2012, had a 1.500" diameter. The second generation of crankpins, in use since 2013, features the larger 1.671" (OEM diameter) crankpins. S&S and OEM crankpins are now identical in diameter, meaning S&S parts can be used to rebuild standard H-D flywheels, something that was previously impossible as H-D rebuild parts were not, and are not, available.
Note: The following applies to 03-17 models. S&S designed these flywheels to work with a Timken-style pinion shaft bearing; they fit factory H-D cases on 99-02 models and all S&S cases without modifications. Factory H-D Twin Cam engines from 03-17 use the same pinion shaft roller bearing as on the pinion shaft, a cheaper but less strong solution. It is possible to use the weaker factory 03-17 pinion shaft bearing kit (OEM H-D 24004-03B) with S&S flywheels in factory 03-17 cases. However, S&S believes this roller bearing will not withstand the side loads produced in a high-performance engine. S&S will not honour any warranty claim in applications where the roller-style pinion shaft bearing assembly OEM 24004-03B/24605-07 03-17 is used. To upgrade to the pre-2003 pinion shaft bearing style, the MCS 978517 JIMS conversion tool kit is available. This kit includes one tool, one Timken bearing and one steel crankcase bearing insert for one engine. Bearing inserts are available separately as 978519, and bearings separately as 508960.
Note: In all applications, the technician must be able to assess the components to determine their suitability in combination with the other engine components, prior to installation. It is important that a qualified mechanic installs them and makes the necessary adjustments.
