This is a direct bolt in upgrade over the stock assembly and solves a number of problems. Added height adjustment in the rear to raise the sprocket up to 2" higher for people lifting the bike and having chain issues. Does away with the factory bushings people are tearing up and uses a solid mount. Adds forward and back adjustment for the engine to be able to dial in belt tension. Side to side adjustment on jackshaft for chain alignment. 1/4" solid steel jackshaft assembly with larger bearings than the stock unit. Overall a bulletproof setup to compliment that built engine without worrying about breaking welds and bending stuff. 4th Picture shows optional mud/rock guard for the front of the engine
