25Mm Crankshaft Extension F*St07-11

In 2006 the OEM transmission for Dyna's and in 2007 for Softails changed from 5 to a "Sportster like" trapdoor mounted 6 speed. With that the complete internals changed including the mainshaft and the output drive gear. All previous available offset kits no longer fit the present OEM 6 speed Big Twin transmissions. Therefore Ton Pels designed a totally new offset kit. This offset kit allows the use of wider swing arms for up to 280 rear tires whilst keeping the wheel perfectly in center with the motorcycle. Kits come with all required parts, such as an extended transmission main shaft and extended main drive gear, primary spacer ring, primary spacer blocks, extended clutch push rod, crankshaft extension and all required gaskets, seals and hardware. The 280 kit also includes an offset frame side plate. Transmission main shaft and main drive gear are CNC machined from High Stress 20CrMnT gear steel forging by one of the worlds leading automotive transmission factories. Gear and shaft are tempered and stress released to a core hardness of 35 to 45 Rockwell and has a surface hardness of 58 to 60 Rockwell. Kit must be used with 20mm rear belt.

Note: Kit for 2012-2013 models also fits earlier models that are equipped with a Screamin' Eagle compensator OEM 40274-08 or 40274-08A. These feature only 1 thrust washer between the sprocket and sprocket retainer. Kit for 2014 to present models also fits earlier models that are equipped with a Screamin' Eagle compensator OEM 36500034A, 40100061, 4220064A or 42200095A. These feature a thrust needle bearing and 2 washers between the sprocket and sprocket retainer.
Note: Wide wheel, tire, swing arm and fender struts must be ordered separately.
