All Mark Williams steel spools are precision machined from 4140 steel forgings on CNC machinery for ultimate precision and accuracy. 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.

The Mark Williams Advantage

• Through hardened alloy steel, not egg-shell-thin hardened case
•  Ring gear mounting diameter is ground to precise press fit
• All mounting diameters concentric and square within .001"
• Increased cross section and generous radius under mounting prevents deforming
• Made in the USA! Forged, Ground, Machined, and Heat Treated in the USA!
