What is the result of evolution? Unorthodox Racing Ultra Street Sets build upon the success of Ultra Street crank pulleys by adding the Ultra Accessory pulleys. Each accessory pulley is made of lightweight 6061-T6 billet aluminum, lighter than the factory piece it replaces, and includes lightening holes where possible. Splines and bores are precision machined for accurate fitment which makes them an excellent replacement for the brittle plastic pulleys found on many late model cars. Premium fit and finish ensures a beautifully matched set you are proud to display under the hood of your vehicle.
