Optimize Accessory Performance with Torque Solution

Unlock more power and efficiency for your Porsche's accessories with the Torque Solution Underdrive Crank Pulley Kit. This kit is engineered to reduce the rotational speed of accessories like the alternator and power steering pump, freeing up horsepower that would otherwise be consumed.

Key Advantages:

  • Increased Horsepower: Reduces parasitic drag from accessory components, freeing up engine power.
  • Improved Accessory Efficiency: Allows accessories to operate more efficiently at higher RPMs.
  • Durable Construction: Manufactured from high-grade materials for longevity and reliable performance.
  • Designed for Fitment: Specifically designed for Porsche Boxster, Cayman, 996, and 997 models equipped with air conditioning (excluding turbo engines).

Vehicle Application:

This underdrive pulley kit is compatible with:

  • Porsche Boxster (986/987)
  • Porsche Cayman (987)
  • Porsche 911 (996/997) - Non-Turbo models with AC

Enhance your Porsche's performance potential with this effective upgrade. The Torque Solution Underdrive Crank Pulley Kit is a smart choice for drivers looking to gain a competitive edge. Find this and other performance parts at GGCRACING!
