This is the McLeod Racing RST HD Twin w/ Steel Flywheel - 15-23 Ford Mustang 2.3L EcoBoost - 1 x 23M Spline. Part mlr64388-25MD. A performance clutch kit replaces the factory clutch to hold more torque and give a more consistent engagement.

The McLeod RST HD Clutch Kit is engineered for performance enthusiasts who demand more holding power than stock while maintaining excellent street manners. Positioned between McLeod's renowned RST and RXT twin-disc systems, the RST HD delivers an ideal balance of drivability and performance enthusiasts with a more spirited driving style.

At the core of the RST HD are dual performance discs design that maximizes both versatility and torque capacity. One side utilizes full-face organic friction material for smooth engagement durability under repeated street and strip use. The opposing side features segmented ceramic friction material, providing increased bite and enhanced holding power when performance demands rise.

This hybrid friction combination enables the RST HD to withstand aggressive driving conditions while preserving the street-friendly characteristics McLeod customers expect. It is an ideal solution for high-horsepower vehicles that see daily street use as well as weekend track duty.

Available in multiple configurations, the RST HD can be paired with an existing compatible flywheel using ringed versions or purchased as a complete package with a dedicated aluminum or steel flywheel for optimal performance and fitment.

Designed for drivers seeking the perfect balance between comfort and capability, the McLeod RST HD is a versatile twin-disc clutch solution rated for up to 950 horsepower.
