Accessory Drive Pulleys & Tensioners

The accessory drive belts on your engine require proper tension at all times, including when the engine speeds up and slows down. But as the belts age they can stretch and flex more than what would normally be allowed. The belt tensioners make sure that the accessory drive belts on your MINI or BMW engine are always at the proper tension to keep the engine and its accessories operating at its best. Browse our catalog below and choose the correct tensioner and pulleys for your application.

Bavarian Autosport has been helping BMW and MINI enthusiasts maintain, repair, and upgrade their vehicles for more than 43 years. Every item we sell comes with a 100% satisfaction guarantee and a MINImum one-year warranty, and a two-year warranty on every part with the Bavarian Autosport brand. Because we use the same manufacturers as BMW, all of our parts meet or exceed the OEM equipment. We have a full team of advisors ready to answer your questions and help you find the right part for your MINI or BMW by phone or email. We even give you free shipping on most orders over $99 and because we're located in tax-free New Hampshire, there is no added sales tax for any purchase.
