OS Giken Nissan Skyline OS-88 Six Speed Sequential Gearbox Option ratio 1

What you get with this OS Giken OS-88 Six Speed Sequential Gearbox is the gearbox itself, configured with option ratio 1. This is a serious piece of kit for anyone looking to upgrade their Nissan Skyline's drivetrain to a true sequential setup. A sequential gearbox allows you to shift gears in a straight line – pull back to upshift, push forward to downshift – which is much faster and more intuitive than a traditional H-pattern shifter, especially in performance driving scenarios.

OS Giken is well-known for its high-performance clutch and drivetrain components, and the OS-88 gearbox is a testament to that reputation. It's built to handle the rigors of demanding use, offering improved shift speed and driver control. The sequential mechanism itself is designed for durability and precise engagement, ensuring that each shift is crisp and reliable. This particular configuration comes with option ratio 1, which is a specific gear ratio setup chosen by OS Giken for optimal performance in certain applications. Understanding your vehicle's powerband and intended use is key when selecting a specific ratio, and this option is a popular choice for many Skyline owners looking to maximize their car's acceleration and top-end performance.

When installing a gearbox like this, it's important to ensure all supporting components are up to the task. This includes clutch, driveshaft, and potentially even engine management tuning to take full advantage of the improved shifting capabilities. OS Giken gearboxes are a significant upgrade, and proper installation by a qualified professional is highly recommended to ensure optimal performance and longevity. This gearbox represents a substantial investment in your vehicle's performance, offering a level of control and speed that transforms the driving experience.
