Fits 2002-2008 Mini Cooper S and JCW (R53 Hatchback and R52 Convertible).

Protect your engine from catastrophic secondary damage with the ALTA Performance Adjustable Tensioner Stop. On the supercharged Mini engine, a snapped serpentine belt allows the spring-loaded factory tensioner to recoil with extreme force. This movement can easily damage the crank pulley, puncture the engine block, or destroy the crankshaft position sensor. The ALTA tensioner stop serves as a mechanical fail-safe, limiting the tensioner's travel to prevent these components from being impacted.

Built for durability and precision, this adjustable stop allows for fine-tuning to ensure proper clearance during normal operation while providing immediate protection during a failure. It is an essential upgrade for any supercharged Mini, particularly those with reduced pulley sizes that place higher stress on the belt drive system.

• Function: Limits tensioner travel to prevent engine damage during belt failure.
• Adjustability: Fully adjustable design for precise clearance setting.
• Chassis Compatibility: Fits R53 (Hatchback) and R52 (Convertible) models.
• MPN: AMP-ENG-195BK

Fits 2002-2008 Mini Cooper S and JCW models (R52/R53).

The ALTA Tensioner Stop (Non-Adjustable) is a critical safety upgrade for the supercharged R52 and R53 platforms. In the event of a serpentine belt failure, the factory spring-loaded tensioner can swing back with enough force to damage the crank pulley or other engine components. This stop acts as a mechanical limit, catching the tensioner arm before it can cause costly secondary damage.

• Prevents the belt tensioner from striking the crank pulley during belt failure
• Designed specifically for the R52 and R53 supercharged engine layout
• Rugged construction with a fixed, non-adjustable design for simplified installation
• Helps protect the timing cover and accessory drive system
• Manufacturer Part Number: AMP-ENG-190
