Racing Timing Belt Kit – Mazda MX-5 NA/NB

Upgrade your MX-5’s reliability and performance with our Racing Timing Belt Kit.
Designed for both naturally aspirated and forced-induction builds, this kit ensures maximum strength and heat resistance compared to standard aftermarket belts.

We’ve trusted this exact Gates Racing belt for years on our own all-motor 1.9L build — it has never failed us. Enthusiasts worldwide rely on these belts for peace of mind, knowing that a timing belt failure on a high-compression engine usually means catastrophic damage. (Sure, some low-compression turbo guys may get away with it, but a broken belt is still the end of your track day.)
