March Performance Chevy LS Series Serpentine Kits
March Performance Chevy LS Series serpentine kits offer an exciting new look when mounting an accessory drive in your vehicle. They're designed for vehicles that do not have air conditioning. The driver side features a remote power steering pump with an attractive aluminum cover, while the passenger side has March's own billet alternator (except where noted). An OEM-style tensioner ensures perfect belt tension. All pulleys and brackets are CNC-machined from 6061-T6 aluminum for strength and perfect fit—and hard-coated on high wear areas for durability. Order the kit recommended for your vehicle.
