The NonStopTuning Honda Civic Si Pulley Kit increases horsepower via great weight reduction and the underdriving of accessories. Superior to other available kits, the NST kit offers an Overdrive Alternator Pulley to optimize output for stereo system lovers!

To make things even better, the NST Civic Si K20 kit is the only kit on the market that offers a third pulley. The new NST Belt Idler replaces the OEM idler and allows installation while retaining the OEM Honda Belt. No need to search for a new belt.

Each kit is carefully crafted from 6061-T6 aircraft aluminum, tested and balanced to high tolerances. Every NST pulley is hard anodized for exceptional durability and is available in a choice of colors: Red or Graphite Gray.
