1. A Single disc application is installed with the completely flat side facing the flywheel. The protruding side of the hub (side with springs) assembly will face up towards the pressure plate ( in most cases)
2. A double-disc unit will have both hubs with the protruding side of the hub face up towards the pressure plate and towards the transmission. (in most cases)

The McLeod RST HD achieves this balance through an innovative hybrid twin-disc design that places less stress on your drivetrain. Instead of using identical friction materials on both sides of the discs, the RST HD uses a dual-performance configuration:

• The Street Side: Features a premium, full-face organic friction material that delivers the ultra-smooth engagement, zero chatter, and soft pedal effort you expect from a daily driver.

• The Track Side: Features a high-coefficient, segmented ceramic friction material that provides the aggressive bite and massive torque-holding capacity needed to handle up to 950 HP.

By engineering these two distinct materials to work together, McLeod bridges the gap between comfort and capability—giving you an economically priced twin-disc clutch with excellent street manners that won't slip when you push it on the track.
