ALTA Tensioner Stop for 02-06 Mini Cooper S/JCW & 02-08 S/JCW Convertible R53

The ALTA Tensioner Stop is a robust, non-adjustable solution designed to replace the OEM hydraulic belt tensioner dampener on supercharged MINI Cooper S and John Cooper Works models from 2002 to 2006, including the 2002-2008 Convertible R53 models. This upgrade eliminates tensioner bounce, adds more tension than the stock dampener, and improves belt stability under extreme driving conditions.

By preventing premature belt failure and reducing slippage, the ALTA Tensioner Stop enhances throttle response and protects critical engine components such as the crank pulley from damage in the event of belt failure. Installation is straightforward, requiring only slight motor lift and no removal of the tensioner assembly, saving valuable labor time.

  • Non-adjustable design for reliable belt tension
  • Eliminates tensioner bounce and pulley noise
  • Increases belt tension beyond OEM dampener capabilities
  • Protects crank pulley and engine components from damage
  • Simple installation without removing tensioner assembly
  • Compatible with supercharged MINI Cooper S/JCW R53 models 2002-2006 and Convertibles 2002-2008
