Just released and in stock here at Euro Styles East!

An easily installed product for those wanting the performance associated with a 19% reduction SC pulley but already have a 15% reduction pulley installed. Just couple your 15% SC Pulley with Alta's 4% larger crank pulley to effectively equal a 19% SC Pulley!

Also, please consult our application chart for the correct serpentine belt for your setup:
