Running a Big Inch High Horsepower engine together with a 1 1/8" or 1 1/2" belt may give trouble. If you want a sure way to safely transport all that power to the rear wheel the way to go is the 2" final beltdrive system from Primo Belt Drive Systems. The 2" wide 65 tooth rear pulley has a solid design and machined out of aluminum and has a 2" inner diameter. Transmission pulley has 32 tooth and is also machined from aluminum. The 132 tooth belt is an HTD type polychain and is manu-factured by Gates. Capable of handling more power the kit provides you a better ride and a more comfortable feeling. Due to the extra width of the pulleys the 2" belt drive system must be used with extended mainshaft and primary off-set). The off-set required depend on the width of the rim/tire combination used (off-set is required even when stock rim width is used). It may also be required to install a wider swing arm. On Right Side Drive Transmissions the use of an actuator spacer and extended clutch pushrod is a must. Fits 5-Speed and aftermarket 6-Speed models. Does not fit 2006 and later Dyna or 2007 and later Softail and Touring.
Note: For obvious reasons we strongly recommend that a craftsman or certified mechanic installs these 2" drives.
