Notes:
Belts are not included and must be purchased separately, kit requires 43.6 in. and 54.8 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. This kit also fits Mopar Performance Hemi crate engines. If you have an aftermarket damper, please call March before ordering (239-593-4074).
March Performance Big Block Chrysler Deluxe Serpentine Conversion Kits
March Performance Big Block Chrysler deluxe serpentine conversion kits simply swap out with your old low-performance V-belt pulleys with a 1 in. wide serpentine belt drive system. Not only will they eliminate belt throwing, March high water flow ratio pulleys will also improve cooling. These high-performance pulley kits are precision CNC-machined from solid billet 6061-T6 aluminum, and then polished and clear powdercoated for a no-polish, maintenance-free finish.
