GReddy Lightweight Performance Pulley Kit for Mazda RX7

Parasitic loss is a common issue in engines. GReddy lightweight pulleys are a perfect way to lower parasitic loss by reducing the mass the engine needs to move. Standard pulleys tend to be heavy and really drag the engine. By replacing them with lightweight pulleys, the engine does not need to work as hard to power your accessories, freeing up some power. Made in lightweight, yet strong, Duralumin and finished in a vibrant blue color, ensures these are not just functional, but also good looking as well.

Key Features:

• Strong, yet light design.
• Better throttle response, improved acceleration, and more power.
• Increase in fuel economy, normally by about 1-3 MPG.
• Smoother engine operation (each pulley is engineered to exacting standards for weight distribution).
• Available in a blue color only.
