Zippers has taken the hassle of converting your late model belt driven H-D® to chain drive. Whether you’re interested in a different final drive ratio, added driveline strength or more clearance for a wider tire, these kits will make your life easier. Kits are available with durable, high wearing RK Pro O-Ring chains (best for street use). Comes standard with metallic finish Oring chain and Aluminum rear sprocket. Call for additional rear sprocket materials and chain options, because belts are for pants.
