March Performance Performance Series V-Belt Pulley Kit to Fit 1969-1/2 and Newer Mustangs with 302/351W Engines.
March Performance's Performance Series V-belt pulley set replaces your low-performance OEM V-belt pulleys while retaining your standard rotation water pump. Designed for normal street driving and simple to bolt on, this pulley set increases horsepower 12.5-15 h.p. at the rear wheels by reducing accessory drag. CNC machined from solid billet 6061-T6 aluminum for extra strength and wear resistance, these pulleys will run perfectly true, eliminating thrown belts. Finished in either a "No Polishing" clear powder coat or black powder coat.
