Aluminum Spools

    
In the never ending battle to reduce rotating weight, Mark Williams offers spools manufactured from aluminum and titanium. MW’s aluminum spools are successfully being used in Pro Stock, Comp, Super Comp, Super Gas and Stock eliminator cars. They are machined from 7075-T6 aluminum alloy forgings and hard coat anodized for durability. Aluminum spools are approximately half the weight of the profile milled steel spools. 35 spline aluminum spools are currently available for 9” Ford, 8 3/4” Mopar and Chevy 12 bolt rears. 40 spline spools are available for 9” Fords as well as Dana 60 rears. 28 and 31 spline aluminum 9” Ford spools are also available but recommended only for oval track racing. A 9” Ford 40 spline titanium spool for high horsepower applications is also available by special order. Aluminum 9” Ford 40 spline spools must be used in a case with a 3.812” bore while the 35 spline aluminum 9” Ford spool requires a case with a 3.250” bore. 9” Ford 40 spline steel spools are available for 3.25 and 3.812” bore cases.
 
MW Advanatages:
  • 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
  • Models accomodate 28, 31, 35, and 40-spline axles
  • Models allow using 35-spline axles with 2.893 and 3.062 O.E.M. case bore sizes

 

Notes:

  1. G.M. applications require C-Clip eliminator or other axle retention method.
  2. 40 spline spools require 45 mm bore wheel bearing and matching housing ends.
