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!
How it Works
The ALTA Tensioner Stop hooks around both ends of the tensioner dampener and limits the travel of the tensioner arm. ALTA designed it to limit the travel of the tensioner to the same point as the OEM tensioner. Thus allowing unhindered travel and operation of the tensioner but only to the point at which the OEM tensioner stop fails.
