Description
Dinan's lightweight billet aluminum crankshaft pulley underdrives each of the accessories by 13 percent, reducing parasitic drag on the engine for a 6 HP @ 8000 RPM and 4 lb-ft torque @ 8000 RPM gain on a stock vehicle. The Dinan underdrive pulley retains the factory harmonic crankshaft damper, eliminating vibration that might otherwise damage the crankshaft.
