March Performance Accessory Drive Pulley Set

March Performance Accessory Drive Pulley Sets: Precision Engineering for Your Engine Bay

When it comes to accessory drive pulley sets, few names carry the credibility and craftsmanship that March Performance has built over more than 30 years of aircraft and automotive manufacturing experience. Based in Naples, Florida, March Performance has spent decades refining what it means to engineer a pulley set that delivers on three fronts simultaneously: durability, performance, and show-quality style.

What Sets March Performance Pulley Sets Apart

The foundation of every March Performance accessory drive pulley set is 6061-T6 aircraft-grade aluminum. All components are made with quality materials like 6061-T6 aircraft-grade aluminum, and March uses precision CNC machining to guarantee efficient and reliable operation. This isn't just marketing language — the same alloy specification used in aerospace applications translates directly to corrosion resistance and structural integrity under the heat and stress cycles of a performance engine.

Beyond raw material quality, March goes further with a critical surface treatment. March hard coats all high-wear surfaces to increase pulley life, hardened to 65 Rockwell "C" scale — harder than steel and two times harder than forged aluminum. This means the grooves that contact your belts day after day resist wear far longer than conventional pulleys, maintaining belt tracking precision over the life of the part.

Finish quality is another area where March Performance distinguishes itself. All March Performance brackets and pulleys feature clear powder coatings that eliminate the need for laborious polishing in hard-to-reach places, using only the finest powders — guaranteed not to chip or yellow. Whether you're building a weekend show car or a dedicated track machine, the engine bay presentation stays sharp without ongoing maintenance.

Performance Ratios That Work

March Performance accessory drive pulley sets aren't just about aesthetics. Performance underdrive ratio pulley kits truly reclaim lost horsepower, with some applications seeing as much as a 15 HP gain. Underdrive pulleys work by slowing down the front engine accessories by changing the size and ratio of the pulleys, reducing parasitic drag from the alternator, power steering pump, and other driven components. For street rod and classic muscle car builds, High Water Flow Ratio pulley kits increase cooling by speeding up water flow and fan speed, helping to keep your engine running cool during critical low-speed driving.

Coverage Across Major Engine Families

March Performance provides premium pulleys and brackets for a variety of engine types, including Ford, Chevy, Chrysler, and more. This broad application coverage — spanning small-block and big-block platforms as well as classic and modern engines — makes March a go-to source whether you're restoring a vintage muscle car or building a restomod from the ground up.

Built in the USA, Backed for Life

All March billet performance pulleys, brackets, and serpentine brackets are made with pride in the USA. And because March Performance stands behind their engineering, all V-belt and serpentine kits are backed by a lifetime warranty. For a pulley set that you install once and rely on indefinitely, that commitment to long-term quality is hard to overlook.
