Many customers are requesting that Precision Parts also supply the appropriate drive belts and heavy-duty NULINE idlers pulleys to suit. This is particularly important as vehicles age and bearing wear in the pulleys require them to be replaced when the drive belts come off.
Even for low mileage vehicles the NULINE pulleys offer distinct advantages in that they are all metal construction and therefore much stronger and wear resistant than the original plastic units. The pulleys also feature heavy-duty high-speed bearings for performance use.
Powerbond underdrive pulley kit reduces parasitic power losses associated with high accessory speeds, freeing up additional HP. It also reduces the rotating inertia on the front of the crankshaft allowing for faster revving.
Under-driving the accessory pulleys reduces parasitic power losses from the alternator, air conditioning, water pump and power steering at high engine RPMs. A smaller, lighter harmonic balancer is like a lightweight flywheel and can sharpen throttle response and allow the engine to rev out faster.
What do Underdrive Pulleys do? 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. All pulleys are manufactured from Billet Steel or Aluminum, exceeding factory quality.
