Alright, so you're building a rotary and need that aggressive whine?

Check out this Gilmer Drive Pulley Kit.

It's got that sweet titanium color and is made from solid billet aluminum, so it's light but super strong.

This specific kit is made to fit the classic Mazda rotary engines like the 12A, 13B, and even the 20B in your RX7 FC, FD, or RX3.

It uses a 1.5 notch belt and is sized at 15mm.

This is a new, unused part straight from the manufacturer.

It comes with a warranty, so you can install it with confidence.

Perfect for anyone looking to ditch the stock serpentine setup for a more reliable and great-sounding direct-drive system.

Made in China.
