Lately we have seen several stock Crank Pullies on the 02-06 Cooper S. Now there is a new choice rather than the OEM one that failed, and this isn't a lightweight Aluminum pulley that has NO dampening, so this won't wear out your crank bearings. Helping your engine last.
This Super Damper designed a 5.5” damper -- Part # 917992 -- for the Mini Cooper standard and S engines. This new design is a direct replacement for the stock OEM Mini Cooper and Mini Cooper S damper from 2001 through 2006. The heart of this unit is the tried and true “damper within a damper” design that has put ATI ahead of the rest. The outer shell has been machined to allow OEM serpentine belt locations, and includes laser-etched timing marks.
