Always made using only virgin billet aluminum, a handsome anodized finish, and the tightest tolerances; our pulleys are used on some of the fastest BMWs on the planet. Our very lightweight design optimizes performance and response while under-driving components just the right amount for proper function at all RPMs. Quality is always #1, and you can be sure these pulleys will fit right and last a lifetime, replacing BMWs crack prone plastic pulleys.
