The Ralco RZ 914109 is a high-performance crank pulley conversion engineered to enhance your Honda Civic's responsiveness and power output. Constructed from premium 6061 aluminum billet, this pulley is significantly lighter than OEM components, directly contributing to performance gains.

The product includes a 3-set pulley kit, encompassing the Crank, Alternator, and Water pump pulleys.
