If your looking to dial in your trans, one one fail swoop, heres a 100% complete kit. Other companies offer an incomplete kit, but we've included the proper amount of shims, and a malossi belt!. Less work for you :). Tfc cnc bell, wrapped around a tfc clutch, contra spring, on top of a tfc pulley topped off with a slick nut. Doesnt get much better than that. Our kit also includes the TFC pulley, drive face, ramp and rollers. Remember this kit is for the af16 size crank. There are SOME af18 large spline cranks, but PLEASE verify before purchasing.
