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.
- Lightweight billet aluminum crankshaft pulley, black anodized and engraved.
- All accessories are underdriven by 13% to decrease drag on the engine.
- Includes mounting hardware and shorter belts.
