The Ford Flathead 1949–1953 All-Inclusive Style Track Serpentine System from March Performance brings modern reliability and classic style together for your vintage hot rod. Designed to replace outdated V-belts, this 6 rib serpentine setup delivers smooth, no-slip operation and efficient accessory performance — even in tight engine bays. Its compact inward-mount design positions the alternator and A/C neatly within narrow hoods, while dual idlers ensure maximum belt contact. Precision CNC machined from 6061-T6 billet aluminum, every component is built for strength, perfect fitment, and maintenance-free performance. Available in clear, black, black onyx, or chrome finishes, this American-made system transforms your ’49–’53 Ford Flathead into a showpiece of engineering and style.
