{"product_id":"mcs915284","title":"99-06 4-3\/8\" Stroke Flywheel Assembly – 1999–2006 Twin Cam","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eUsed with 93\/103\/106 and 110\/117 engines. Balanced to 1035 gram total piston weight. Note: Engines with strokes exceeding 4\" may require S\u0026amp;S piston oiling jets and piston to jet clearance notches in the piston skirt to avoid contact. Note: S\u0026amp;S crankpins allow the use of replaceable bearing races in the lower end of the connecting rods. The first generation of S\u0026amp;S crankpins; in use up to 2012; were 1.500\" diameter. The second generation crankpins; in use since 2013; have the larger 1.671\" OEM diameter crankpins. Now S\u0026amp;S \u0026amp; OEM crankpins are identical in diameter so now S\u0026amp;S parts can be used to rebuild stock H-D flywheels; something that previously was not possible since H-D rebuild parts were; and are; not available. Note: Following is regarding 03-17 models. S\u0026amp;S has designed these flywheels to work with a Timken style sprocket shaft bearing; they will fit stock 99-02 model year and all S\u0026amp;S cases without modifications. Stock H-D 03-17 Twin Cam engines use the same sprocket shaft roller bearing as is used on the pinion shaft; a cost saving but weaker solution. It is possible to use the stock weak 03-17 sprocket shaft bearing kit (OEM H-D 24004-03B) with S\u0026amp;S flywheels in 03-17 stock cases. However; S\u0026amp;S feels this roller bearing will not take the side loads produced in a high performance motor. S\u0026amp;S will not honor any warranty claims in an application where the OEM 24004-03B\/24605-07 03-17 sprocket shaft roller bearing style bearing assembly is used.
