Whether you’re dealing with a spun bearing on your Mazdaspeed 3 or building a high-compression N/A monster, the heart of your build is the crankshaft. For JDM enthusiasts, a reliable rotating assembly is the difference between a podium finish and a catastrophic failure. Our Mazda 3 Crankshaft kit is a comprehensive, precision-engineered solution designed to restore factory-spec tolerances or provide a robust foundation for your next performance upgrade.

The AP01 series is renowned in the aftermarket world for providing OE-quality performance at a fraction of the dealership price.

This is an amazing find. It’s actually the original manufacturer spec crankshaft. I didn’t think that the quality would be that good for the price. Thanks, JCDCAuto. You are my new plug for rebuilds. Highly recommended.

Really helpful staff. Car had its belt done here, and when i needed advice, they were so helpful. It wasn't my belt. It was another issue. But thank you for being so helpful, so I appreciate it.

Great stock of nippon spares. Came quite in handy for last Skyline replacement. Delivery took about 6 days to get to me in Dublin. Would 100% recommend.

- Darren O. 🇮🇪

My son’s car had had a diagnostic elsewhere. It needed a new turbo and after speaking to Josh I felt confident that he would do a good job. He arranged recovery and called me with updates about the car. Absolutely brilliant customer service and very honest.
