Left hand threads used to be used on the ring to carrier units. The ring is threaded left hand. They thought the darned things would come loose back in the days before locktite, IIRC. Extra steel is an extra steel shim in the twin grip clutch pack to tighten it up!

The loads inflicted on the rear axle are much different between the two forms of racing. And for the love of me I cannot figure out what a 390 left hand thread twin grip w/an extra steel is?? Does the extra steel mean an additional steel plate in the twin grip mechanism?
