What is a sequential gearbox and how does it differ from a standard manual transmission?

A sequential gearbox allows you to shift gears in a linear pattern: pull back for upshifts and push forward for downshifts. This is much faster and more direct than the H-pattern found in most manual transmissions, making it ideal for performance driving.

What does 'Option ratio 3' mean for this gearbox?

The 'Option ratio 3' refers to a specific set of gear ratios chosen by OS Giken for this particular gearbox configuration. These ratios are selected to offer a certain balance of acceleration and top-end speed, tailored for performance applications.

What kind of modifications are typically needed to install a sequential gearbox?

Installing a sequential gearbox often requires custom work. This can include modifying or fabricating new driveshafts, shifter linkages, and potentially the transmission crossmember to properly integrate the new unit into your vehicle's drivetrain.

Product Details

OS Giken is well-known for their high-performance clutch and drivetrain components, often found in serious performance builds. This OS-88 six-speed sequential gearbox is a prime example of their dedication to advanced drivetrain technology. It's designed to replace your factory transmission, offering a significant upgrade in shifting speed and driver control for your Nissan Skyline.

The sequential design means you simply pull back for upshifts and push forward for downshifts, allowing for incredibly fast and precise gear changes. This is a major advantage during spirited driving or track use, where every fraction of a second counts. The gearbox features an option ratio of 3, which is a specific gear ratio setup chosen for its performance characteristics. This unit is built with the robust construction OS Giken is known for, ensuring it can handle the demands of high-horsepower applications and aggressive driving.

When considering a transmission swap like this, it's important to note that it often requires custom fabrication for driveshaft, shifter linkage, and potentially crossmember modifications. While this gearbox is a direct replacement for the transmission itself, the surrounding components will need to be adapted to integrate it into your vehicle's drivetrain. This is a substantial upgrade for enthusiasts looking to maximize their Skyline's performance potential.
