ALTA Tensioner Stop

Why do you need an ALTA Tensioner Stop? SImple! At some point in your MINI's life, the serpentine belt that drives the Supercharger and AC, will fail. When it fails, the OEM belt tensioner mechanism plunges into the crank pulley, destroying the tensioner and crank pulley. The ALTA Tensioner Stop simply hooks around both ends of Tensioner dampener and limits the travel of the tensioner arm preventing damage when the belt fails. This simple and inexpensive part, saves you hundreds of dollars in repairs!
