Product Description

The Comp1 4T-8037-C is a 184mm rigid ceramic triple disc clutch kit engineered for the highest-output K20-powered Honda and Acura builds. Rated from 1,000 to 1,500 hp, this assembly is designed for full race applications where even a twin disc clutch is no longer enough. The triple disc configuration achieves its massive torque capacity through increased friction surface area rather than extreme clamp pressure, which results in reduced drivetrain stress and a more manageable pedal feel compared to single or twin disc race clutches at similar power levels.

The kit ships complete with a 4140 forged steel flywheel, three ceramic rigid discs, throwout bearing, alignment tool, and pilot bushing - everything needed for a full clutch replacement. No transmission modifications are required for installation, and all assemblies are plug-and-play for K20 5-speed and 6-speed applications. Due to the rigid disc design, this clutch is strictly intended for track and drag race environments and is not suitable for street use.
