This ALTA lightened crank pulley is made for Mini Cooper S and JCW R53 models—2002–2006 coupe and 2002–2008 convertible applications—and replaces the factory crank pulley with a reduced‑mass unit. The lightened pulley reduces rotational inertia to help the engine respond more readily to throttle changes and is intended as a direct replacement for the specified R53 engines.
