OS Giken Overhaul Kit A Subaru STi EJ25 (Incl. Clutch Discs/Center Plate/PP - NO Repl. Cover)

OS Giken is well-known for making high-performance clutch components that can handle serious power. This Overhaul Kit A is built specifically for the Subaru STi with the EJ25 engine, giving you the essential parts to rebuild your clutch system. It includes the clutch discs, a center plate, and the pressure plate, all designed to work together for reliable engagement and power transfer.

This kit focuses on the core friction and clamping components. You'll find the clutch discs are made with durable materials to withstand repeated engagement and high torque loads typical of performance driving. The center plate ensures proper alignment and smooth operation, while the pressure plate provides consistent clamping force. It's important to note that this kit does not include a replacement clutch cover; you will need to reuse your existing one or source a compatible replacement separately. This approach allows you to focus on the wear items that most directly affect clutch performance and longevity.

When rebuilding your clutch, having all the necessary friction surfaces and the correct clamping mechanism is key to a successful installation and optimal performance. This OS Giken kit provides those critical pieces for your EJ25 engine. Remember to consult your vehicle's service manual or OS Giken's installation guide for the proper procedure and any additional components you might need, such as pilot bearings or release bearings, to complete the job thoroughly.
