Description
March Single-Groove Aluminum Crank Pulley — 15% Underdrive
Part No. MAR-13011-08 | Finish Black | Family V-Belt Pulley |
A single-groove billet aluminum crankshaft pulley for the Pontiac V-8, cut 15% under the factory diameter. Underdriving the crank slows the water pump and alternator at speed, which frees up parasitic horsepower and takes load off the front of the engine — a straightforward gain on a street or strip build. Direct factory-replacement fit.
