OS Giken Nissan Skyline FS5W30A Trans 3-Speed Close Ratio Gear Kit

If you're looking to get the most out of your Nissan Skyline's performance on the track or in spirited driving, a close-ratio gear set for your FS5W30A transmission can make a notable difference. This 3-speed gear kit from OS Giken is designed to bring your gears closer together, allowing the engine to stay in its powerband more effectively during acceleration. This means less time between shifts where the engine RPM drops significantly, leading to quicker acceleration and a more responsive feel when you're pushing the car hard.

OS Giken is well-known for producing high-performance drivetrain components, and this gear kit is no exception. It's built with precision and durability in mind, using strong materials to withstand the increased stresses of performance driving. The close-ratio design is particularly beneficial for racing applications or any situation where maximizing acceleration is key. Installing a gear set like this involves a full transmission rebuild, so it's a job best suited for experienced mechanics or those comfortable with detailed internal transmission work. The kit includes the necessary gears to modify three specific speeds within your transmission, giving you a significant advantage in acceleration out of corners or from a standing start.

When undertaking a transmission rebuild for a close-ratio gear set, it's important to have all the necessary supporting components ready. This includes new bearings, seals, and potentially a new clutch kit to handle the increased power delivery. OS Giken's commitment to performance means this kit is engineered to integrate seamlessly into the FS5W30A transmission, providing a solid option for enthusiasts serious about optimizing their Skyline's performance.
