GReddy 03+ RX-8 Lightweight Pulley

This GReddy lightweight pulley is made from a solid aluminum construction, weighing in at just 1.2 lbs. By reducing the rotational mass on your engine's crankshaft, you can expect a more responsive feel from your 2004-2011 Mazda RX-8's rotary engine. Less weight spinning means the engine can rev up and down more freely, which can make a noticeable difference in how the car accelerates and decelerates.

Swapping out the stock pulley for a lighter one is a common modification for RX-8 owners looking to free up a little extra performance. The aluminum construction is well-built and designed to handle the demands of daily driving. It's a straightforward replacement for the factory part, and the improved engine response is often one of the first things drivers notice after installation.
