Overview
March Performance Mopar Big Block Ultra Drive Serpentine Kits
March Performance Mopar big block Ultra Drive serpentine conversion kits solve the problem of unreliable V-belt accessory drives for Chrysler 383-400 and 400 applications. No more belt throwing or slipping! A unique combination bracket mounts the alternator and A/C in a compact manner. March's power steering bracket accepts a standard Saginaw pump (or their own billet pump, for added style). The idler guarantees plenty of belt wrap for high performance, no-slip operation. Kit components are precision CNC-machined from 6061-T6 aluminum for strength and perfect fit; they're finished with a clear powdercoat.
Ultra kits include:
* Combination alternator / air conditioner bracket and rear support
* Power steering bracket, support, and pulley with cover for 1966-74 Saginaw keyway power steering pump
* Water pump pulley and nose cover for Chrysler big block 383-440, 426-440 Hemi water pump
