    (NEW) HKS Sequential Transmission – Mazda RX-7 FD3S

    $1,200.00

    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.

    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.
