Product Description

Product Name: Subaru EJ20/EJ25 Racing Clutch


Main Specifications:

• Number of Friction Plates: 3

• Friction Plate Diameter: 185mm

• Number of Spline Keys: 24 Teeth

• Material: Chromoly Steel

Product Description:

This clutch is designed for racing applications of Subaru EJ20 and EJ25 series engines. Made of chromium-molybdenum steel, it

 has extremely high strength and durability, can withstand high-speed and high-torque workloads, and is suitable for 

high-performance driving and track use.

• Three-plate friction plate design: provides higher torque carrying capacity and smoother power transmission, suitable for 

racing cars that require fast gear shifting.

• Friction plate diameter 185mm: This size is carefully designed to balance the power output of the engine with the 

responsiveness of the clutch, ensuring good performance in a racing environment.

• 24-tooth spline key: ensures precise fit between the clutch and the flywheel or other transmission components, reduces 

wear and unnecessary clearance, and improves power transmission efficiency.

• Chrome-molybdenum steel material: provides higher tensile strength and fatigue resistance, can maintain efficient 

operation under extreme driving conditions, and reduce the risk of failure caused by material fatigue.

Application scenarios:

• Designed for high-performance racing and track applications.

• Provides precise and reliable shifting experience to ensure the stability and controllability of the racing car at high speeds.

• Especially suitable for high-speed and high-load racing environments.


This clutch is not only suitable for Subaru's EJ20 and EJ25 engines, but also can significantly improve the power performance 

and durability of the racing car, and is widely used in various racing events.
