Converts '09 and up FLT Touring models to chain drive for aggressive riding & big horsepower engines. Each kit features specially designed front & rear sprockets that allow for bolt-on installation, eliminating the need for grinding the inner primary for clearance. Retains factory gear ratio. Both sprockets feature a drilled jagged style that is both heat treated & coated for long-term durability. Cush drive assembly is CNC machined from billet aluminum & finished in black anodize. Requires use of 530 chains that are 130 links long, chain will need to be cut down to size (chain sold separately). Works with both factory & aftermarket Cush Drive rear wheels.
