Notes:
Belts are not included and must be purchased separately, kit requires 41 in. and 42.5 in. belts, see the “Suggested Parts” tab. Big block Mopar kits require that the thermostat housing run parallel to the radiator. If your thermostat housing angles toward the radiator this kit will not fit. This kit must be used with canister style power steering pumps with a keyway type pulley. If you have an aftermarket damper, please call March before ordering (239-593-4074).
March Performance Chrysler Serpentine Conversion Pulley Kits
March Performance Chrysler serpentine conversion pulley kits replace your low-performance V-belt pulleys, while retaining your standard rotation water pump. These pulley sets are simple to bolt on, increase horsepower, and eliminate belt throwing. The pulleys are CNC-machined from 6061 T-6 aluminum, hard coated for extra strength and wear, and have a no-polish, clear powdercoated finish.
