Poorly engineered underdrive units can lead to a loss of power steering and poor voltage at lower rpm's. Add additional horsepower to your race car while keeping all systems go with PSC underdrive serpentine pulley kits. These smaller pulleys slow the system's rate of rotation, providing 5 to 15 hp gains at the wheels. The higher rpm's involved in racing allow for greater reductions, but should be approached cautiously on street vehicles. The pulleys in these kits are machined from aircraft-grade aluminum for incredible strength-to-weight ratios. When every bit of horsepower counts, equip your ride with a PSC underdrive serpentine pulley kit.
