At 11.8 lbs it's roughly 8 pounds under the factory unit — a large amount of rotating mass gone from the crank on an AWD chassis.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eOne-piece construction with an integral ring gear.\u003c\/strong\u003e Less opportunity for failure, uniform heat transfer from the clutch disc, and no warped inserts or loose ring gears. Heat-treated forging for strength and toughness with an induction-hardened ring gear for maximum life. Material is distributed for strength, heat tolerance, and rigidity rather than simply removed.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eCNC machined and dynamically computer balanced for smooth high-RPM reliability.
