You asked & now you shall receive! ASP has finally released it's underdrive dampner and pulley combo for the 2005-10 Mustang 4.0L V6! This pulley combo features a 25% reduction in accessory drag and includes required belt.
Underdrive pulley systems increase engine horsepower by reducing the amount of power required to drive external engine accessories. For example, the alternator, power steering, water pump and air compressor rob horsepower from the engine. By replacing factory-sized crank and accessory drive pulleys with a resized pulley, the accessories are slowed, resulting in more horsepower available to the drive wheels.
Look for gains of 15+ horsepower and 10+ ft/lbs of torque with these easy bolt on!
ASP - Quality. Performance. Products.
ASP is one of the industry's leading producers of Mustang performance pulleys. Since 1988 ASP has been machining underdrive pulleys in house to give you the most performance for your Mustang. Each pulley goes through a CNC lathe for accurate measuring and cutting. The pulleys go through 2 cycles and a quality check to ensure each part is perfect before it leaves out of the door.
