Summit Racing Equipment carries crankshaft pulleys for a wide variety of applications, including stock replacement, period-correct restoration, engine dress-up, and high performance. V-belt, serpentine, or Gilmer belt, you’ll find the perfect pulley right here!
“Parasitic horsepower loss” means that some of the power made by your engine is eaten up by driving the accessories. High-revving competition vehicles can get away with a smaller underdrive pulley, which drives the belt less quickly. Alternatively, if you’re adding power-hungry systems like mobile entertainment, an air compressor, or upgraded air conditioning, you may need a larger overdrive pulley to help the alternator keep up.
