FD3S racing transmission

The (NEW) HKS Sequential Transmission – Mazda RX-7 FD3S is one of the most sought-after drivetrain upgrades ever produced for the legendary RX-7 platform. Designed by HKS for motorsport applications, this genuine sequential gearbox delivers lightning-fast gear changes, exceptional durability, and the confidence needed to handle high-horsepower rotary setups.

As a discontinued and increasingly difficult-to-find component, this transmission has become highly desirable among RX-7 enthusiasts, collectors, professional race teams, and serious performance builders. Unlike a conventional H-pattern gearbox, a sequential transmission allows rapid upshifts and downshifts through a simple forward-and-back shifting motion, reducing shift times and helping drivers stay focused on performance.

This particular unit is brand new and never installed, making it an exceptionally rare opportunity to own a genuine HKS motorsports transmission. Included with the package is an OS Giken triple plate clutch, providing a complete high-performance drivetrain solution for demanding street, track, drag, and circuit applications.

Whether you’re building a dedicated race car, a high-powered street machine, or preserving rare JDM performance parts, the (NEW) HKS Sequential Transmission – Mazda RX-7 FD3S represents a premium upgrade with proven motorsport heritage.
