The Speedtek AZ-6 6 Speed Dog Engagement Gearset project is moving full steam ahead, and we're flying through the final stages of development.
Designing a completely proprietary transmission kit for the AZ-6 platform has been one of the biggest engineering challenges our team has ever undertaken. With almost 300 individual components modelled from scratch, every single part has been designed, refined and engineered in-house to create what will be the strongest and most capable AZ-6 gearset ever produced.
This isn't a modified factory transmission; it's completely re-engineering of the platform.
Seeing months of CAD work, machining and testing come together is incredibly rewarding, and we can't wait to show everyone the finished product.
The future of the AZ-6 platform is almost here.
