Show original supplier description
The NonStopTuning Underdrive Pulley Set is a 3-piece kit engineered for Honda D17 engines, including components for the crankshaft, alternator, and power steering. Constructed from 6061-T6 aircraft-quality aluminum, these pulleys are CNC machined and rigorously tested for tight tolerances and balance. The hard anodized finish provides exceptional durability, and the pulleys are available in multiple colors, including green. This kit offers a significant weight reduction of 70-75% compared to OEM parts. Beyond weight reduction, the underdriving of accessories contributes to increased horsepower. The manufacturer highlights that NST pulleys are stronger than OEM cast iron alternatives and resist corrosion. Additionally, NST crank pulleys feature necessary oil sleeves and proper timing marks, features not always found on competing products. The company also claims better throttle response and potential fuel economy improvements due to smoother operation.
