Nodular S case or Nodular heavy duty case

31 spline axles will be fine, if you have a good brand. Your weakest link will be the Tru-Trac.

The aluminum "Daytona" pinion support is a good choice with larger pinion bearings which are needed IMHO. The only challenge here is many of the aftermarket aluminum Daytona pinion supports don't offer enough press fit for the front seal & they occasionally push out. Peening 3-4 spots around the outside of the seal helps. If you still have seal issues, let me know & I'll hook you up with a bolt-on seal retainer bracket.

Best wishes.

Ron, are you referring to the Strange/Ford SVT steel case?

Hi Tim,

We don't get them from Ford/SVT so I don't know if we're talking about the same unit. It could be, because Strange makes the stuff for Ford.

The Strange nodular iron "S" case is inexpensive, lightweight & plenty strong for moderate Road Course & AutoX track duty with the 3.062 case bearings & Daytona pinion support (larger pinion bearings).

The regular nodular iron case is stronger & heavier.

When I need stronger than the "S" case, I go with the Strange "HD Pro aluminum" case (still with 3.062" bearings if the application is 31 spline. It's stronger but not such an anchor on weight as the regular Nodular iron case.

I think the case I'm using is the investment cast steel case that Strange makes for Ford racing, C&R Racing built it, suppose to be the same case the cup guys use, it's 10lbs lighter than the N case.

What gears are you running? Considering selling the third member from my DSE axle complete with no miles. Just rolled on never power through.

Believe it to be 4.10 (will verify) but wanting lower myself and probably going aluminum. Just putting it out there.
