Jass Performance Camshaft Locking Tool For Mazda MX-5 NA & NB

Jass’s camshaft tool locks the two overhead cams in place and allows you to easily work on any belts or gears.

The tool is made out of hardened steel and is capable of cracking the cam gear bolts loose, however, with rusted or seised bolts this isn’t always guaranteed. Jass recommends you loosen the bolts with the belt on and car in gear, then install the locking tool.


  • Fits all NA and NB, including imported cars
  • Made with hardened steel



Weight 0.195 kg
Dimensions 15 × 7 × 5 cm

    Works well- product is slightly different to how it is pictured above, but mounts in the same place as shown. I read wrong info (off another site) about the mounting point of the exact version I was sent. This threw me for about 40 mins!

    I had to tap it on with a rubber mallet in the end, as it’s a tight fit, but that’s what’s needed to hold the cams accurately.

    The fit was poor as i had to tap the tool on and I believe it was machined incorrectly as the timing marks would not line up with the tool in place.
