Over the years Gale Banks has made some impressive contributions to the performance industry. This is yet another, Brian.

As luck would have it Solidworks has a number of additional capabilities built into it that play well for components we might design for the aftermarket performance consumer. Two of the more obvious are an FEA capability for localizing and identifying design induced component stress levels and another is a fluid dynamics modeling capability the is quite helpful in modeling fluid flows like this.

If you look at the inside of the cover you will notice the roof and floor have been provided generous radii designed to guide the fluid flow up to and along the roof on its way across the top of the differential housing to the pinion. The inside bottom of the cover also has a generous radius to help smoothly draw the lube off the floor of the diff housing.

Gale's work is frequently in areas that the typical enthusiast overlooks. This most recent effort of his was an excellent example of that kind of attention to detail that he brings to the aftermarket performance table.
