Is the splinepitch the same in a Strange 30 spline spool as on standard axles?

I've always heard that only Mark Williams spools and axles use a non-OEM spline pitch and shouldn't be mixed.

I've also heard that OEM axles shouldn't be used with any spool because they aren't strong enough to keep handling the extra stresses of turning corners, but I've seen some people do it.

I've heard the same thing, but from several different companies over the years. It would be best to call before ordering a spool without axles. That being said, I raced by car with a Dana, Strange spool and shortened stock axles for a long time. When my axles started to twist, I replaced them with Moser axles. Both fit fine. I now have a Dr. Diff spool. My Moser axles fit nice and snug.

I have MW axles and a Strange spool...

I'm going to assume your discussing the axles from a 8 3/4 or is it a Dana 60 with the 30 spline axles? Either way all the current after market axles for the 8 3/4 and Dana 60 with the 30 spline axles use either 30 degree or 45 degree, I'm not sure which is correct Originally Mark Williams used the other non stock angles on his axles and spools but discontinued doing that a long time ago due to customer input according to one of the techs. when I ask him about on their current spline angles several years ago

Thanks for the input, this is for a 8 3/4 #42.

"1. Are all axles with similar spline counts interchangeable?
No! For example, an OEM 35-spline Dana axle and a special MW 35 spline axle are not interchangeable because the MW spline features a 45-degree pressure angle, which differs from stock Dana 30-degree configuration. Mark Williams does, however, offer Hi-Torque forged steel axles with OEM type splines. Please read additional spline text on page 3"
"Spools
A spool is single piece carrier and does not offer any compensation for different rotating speeds in the wheels. Because of additional stresses created by a spool, it is not a good idea to run stock-spline axles with a spool. Spools should be run in race only type applications and are not intended for use on the street."
"4. Involute Splines
All OEM axle differentials have involute splines; their face is slightly curved to provide optimum contact and even pressure distribution during acceleration. Some aftermarket axles are made with straight-cut splines. They are not a correct engineering design and result in sloppy fitting practices. This creates high stress points, which can result in premature spline failure. Only involute spline profiles should be used to assure uniform loading and proper mating properties with spools and OEM components..."
