XTC Underdrive Pulleys - Improve the performance of your Probe in three ways. Underdrive pulleys are an inexpensive solution to more horsepower. By reducing the size of your crankshaft pulley, your power robbing accessories turn slower, resulting in less drag on the engine. That means more horsepower to the wheels! You also get better fuel economy and longer lasting accessories. By careful design and sizing, no adverse effect occurs to cooling or charging systems. All pulleys are top quality & made of machined aluminum.
