Our gearsets have proven themselves across various platforms, and now we’re excited to offer our solution for the popular 6-speed Z33 / Z34 Gearbox.

To make this large-scale project viable at the prices we’re offering, we’re launching a pre-order campaign. The first 50 orders will receive a significant discount.

Full payment is required upon ordering. If you need more time to complete the payment, please email us to discuss options.

This comprehensive kit includes forks, gears, shafts, and dog rings—everything needed to eliminate common issues found in the factory gears and forks.

Here are the gear ratios for optimal strength and performance:

Speedtek Auto Racing Helical Cut Gearset Ratios

These gearsets are designed for rapid quick shifts, offering a very different experience compared to the factory 6-speed Z33 / Z34 synchronized transmission. Additionally, we offer an optional 26 spline input shaft for high torque applications.

We expect these kits to be completed by mid to late 2025.

This kit fits ALL Transmissions CD001 ---- CD009 & JK40.
