This GREDDY TRUST pulley kit is a direct replacement for the factory water pump and alternator pulleys on the Series 1 RX-8. By reducing the overall weight and inertia of the pulleys, the burden on the engine is reduced, helping to improve acceleration performance and throttle response. The anodised blue finish adds a great-looking accent to the engine bay.
- Reduces rotational mass and inertia for improved engine response.
- Made from lightweight and durable duraluminium.
- Finished in a signature anodised blue for a high-performance look.

You will feel a subtle but noticeable improvement in how freely the engine revs. It’s a classic tuning modification that contributes to a sportier engine character.
