What is a close-ratio gear set and why would I want one?

A close-ratio gear set has smaller increments between each gear compared to a standard transmission. This helps keep your engine in its optimal power band more often, leading to quicker acceleration and a more responsive feel, especially during spirited driving or track use.

Does this kit include everything needed for the transmission rebuild?

This kit specifically includes the gears for the close-ratio conversion and 5th gear. It is recommended to inspect and potentially replace other transmission components like bearings, seals, and synchros during the rebuild process for optimal performance and longevity.

Is this a difficult installation?

Installing a gear set requires complete disassembly and reassembly of the transmission. This is a complex job that is best performed by an experienced mechanic or someone very familiar with manual transmission internals.

About this part

Product Details

This kit includes the gears necessary to convert your Nissan Skyline's FS5W30A transmission into a 3-speed close-ratio setup, complete with a 5th gear. OS Giken is known for its high-performance drivetrain components, and this gear set is designed for enthusiasts looking to optimize their transmission's gear spacing for track use or spirited driving. By altering the gear ratios, you can achieve improved acceleration out of corners and a more responsive feel from your engine.

The close-ratio design means the difference in RPM between each gear is smaller, keeping the engine in its power band more effectively. This is particularly beneficial in racing or performance driving scenarios where maintaining optimal engine speed is crucial. The inclusion of a 5th gear ensures that you still have a usable overdrive gear for cruising, balancing performance with practicality. OS Giken uses well-built materials and precise manufacturing to ensure these gears can handle the increased stress of performance driving.

When installing this gear kit, it's important to note that transmission disassembly and reassembly are required. This is a job best suited for experienced mechanics or those comfortable with intricate drivetrain work. You'll want to ensure all related components, such as bearings and seals, are in good condition or replaced during the rebuild to ensure smooth operation and longevity of the transmission. Refer to the manufacturer's installation instructions for specific details on the rebuild process.
