Self-Adjusting Assembly - This design uses a spring-loaded, self-adjusting, wedged ring that rotates to maintain constant diaphragm spring height and pedal effort. As the friction material on the disc wears thinner, the tapered wedged ring rotates, utilizing a thicker section of the ring to compensate. Each self-adjusting assembly must be matched with a special disc design that features a double layer of cushion segments. These segments assist in disengaging the pressure plate while aiding rotation of the wedged ring.

Modular Assembly - Utilizing a variety of diaphragm style assemblies, the modular assembly consists of a diaphragm assembly, disc assembly, AND flywheel that have been riveted together to create a single system. This eliminates potential misalignment, contamination of the disc friction material, and non-compatibility of components while reducing installation time.

Pull-Type Assembly - This design is unique because the release bearing is actually attached to the diaphragm spring. In order to release the clutch, the actuation system is engineered to pull the release bearing away from the pressure plate. Because pull type assemblies typically offer higher clamp loads compared to other diaphragm style assemblies of equal size, they have commonly been used in high-performance sports cars ranging from Porsche applications to General Motors’ Corvette. However, because of their rugged design and performance characteristics, pull type assemblies are gaining popularity in mid-size and compact sports sedans.
