Product Description

The Clutch Masters 08240-HRC6-SK is a high-performance FX400 clutch kit engineered for Honda and Acura vehicles equipped with the K24 2.4L engine. It is designed for drivers seeking a significant upgrade over OEM clutch systems, offering increased torque capacity and improved heat resistance for performance driving conditions. This kit is commonly used in modified vehicles producing higher horsepower and torque levels, where a standard clutch would fail.

Featuring a 6-puck ceramic sprung disc and a high-rev pressure plate, this clutch delivers aggressive engagement with excellent holding power. The included lightweight steel flywheel improves throttle response and reduces rotational mass, enhancing overall engine performance. Due to its lightweight design, an aftermarket tuning solution such as Hondata FlashPro is required to ensure proper engine operation. This system is ideal for street performance builds, spirited driving, and light track use.

Fitment is confirmed for 2012-2015 Honda Civic Si, 2009-2014 Acura TSX, 2013-2014 Honda Accord (various trims with 2.4L), and 2013-2014 Acura ILX with compatible 6-speed manual transmissions. This kit is not intended for stock or lightly modified vehicles due to its aggressive engagement characteristics and ceramic friction material.
