The ring gear register and bearing diameters are precision ground with the spool mounted on a special arbor to assure concentricity between the splines and the ground surfaces and final ground to ensureszero runout on the ring mounting surface. Engineered for maximum reliability, MW spools have an increased cross-section under the ring gear register to prevent ring gear deflection. MW spools are heat treated in-house with the same austemper through hardening heat treat process as our strongest in class MW “Hi-Torque” axles for ultimate strength. MW lightweight spools are profile milled and lightening holes are added to reduce the weight by as much as 25% over the standard version without sacrificing the strength of the spool.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003e\u003cb\u003eThe Mark Williams Advantage\u003c\/b\u003e\u003cb\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"p1\"\u003eThrough hardened alloy steel, not egg-shell-thin hardened case\u003c\/li\u003e\n\u003cli class=\"p1\"\u003e\n\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003eRing gear mounting diameter is ground to precise press fit\u003c\/li\u003e\n\u003cli class=\"p1\"\u003eAll mounting diameters concentric and square within .001\"\u003c\/li\u003e\n\u003cli class=\"p1\"\u003eIncreased cross section and generous radius under mounting prevents deforming\u003c\/li\u003e\n\u003cli class=\"p1\"\u003eMade in the USA!
