driveline components for performance and racing applications since 1961, supplying twin-disc and single-disc clutch systems used across drag racing, road racing, and high-performance street builds.\u003c\/p\u003e\u003ch4\u003eFAQ\u003c\/h4\u003e\u003cstrong\u003eWhat is different about the RST HD compared to the standard RST?\u003c\/strong\u003e\u003cp\u003eThe RST HD uses a hybrid friction combination, organic on one side of each disc and segmented ceramic on the other, for a higher horsepower rating than the standard organic-only RST while retaining reasonable street manners.\u003c\/p\u003e\u003cstrong\u003eDoes this kit include a flywheel?\u003c\/strong\u003e\u003cp\u003eYes, this part number includes a matched steel flywheel.\u003c\/p\u003e\u003cstrong\u003eWhat
