Version 2.5, better and lighter than ever:
The VAC S14 Underdrive Power Pulley Set is better than ever.
Always made using only virgin billet aluminum, a hard anodized finish, and the tightest tolerances, our pulley sets are used on some of the fastest S14s on the planet.
This lightweight design optimizes performance and response while under-driving components just the right amount for proper function. The more power and RPM your S14 makes, the more gain you can see.
Perfect for track cars, they can also be used on a street car without any problems.
- Our pulleys are precision made from 6061 T6 Billet Aluminum
- Hard anodized surface treatment for durability
- Reduces pump cavitation at higher rpm's
- Saves weight when every bit counts
- Includes new, correct length, labeled Contitech belts for WP, ALT, P/S
VAC Technician's Tip:
- For cars with a lot of in car entertainment / stereo equipment, we offer a kit that does not underdrive the alternator
