how fast can you go on a full weight GN with Moser 30 spline axles safely?

The spline count isn't as important as the metallurgy and heat treat imo. If the metallurgy and heat treat are consistent the diameter between the splines could be measured to give an indicator of more potential strength. Usually more splines equals larger diameter. It's onlyjdpolzin said:I dont really understand the axle spline count debate sometimes. I dont really see why a higher spline count would equal higher HP abilities. I personally run a 35 spline Wavetrac center section in a 9" so I cant really talk but as the axle spline count raises, gear or tooth size decreases. I'd like to see some real world testing on different spline count axles with the same pinion size. I'd put my money on it that the lower spline count axles will hold up just as well if not better than the high spline count.
A 26, 28 or 30 spline axle shaft has a different diameter Jeremy, not just the amount of teeth on the shaft. The larger diameter of the shaft and the larger count of the splines means more surface area so it's stronger. If you look at the strength rating on a 3/8" bolt if you go to a fine thread count over a course thread count the strength goes up because of surface area required to pull the thread out. Hope that helps you understand.I dont really understand the axle spline count debate sometimes. I dont really see why a higher spline count would equal higher HP abilities.

I used to run a gn rear with 30 spline mosier axles and a 30 spline eaton posi. When i got the car to 60 foot in the mid 1.3's the posi lasted about 6 passes before the spider gears exploded. I then went with a spool. Got the car running 9.30's with 60" from 1.27 to 1.32 . Broke atleast one ring and pinion a year. Never broke an axle, but the splines did start to twist and the axles tubes bent 3 times before the last ring and pinion went and took out my 400 turbo with it. 100's of passes on the axles even after they started to twist. If you plan on lots of power and low 60 " times save your money and go with a 9 inch.

as good as it's weakest point.
stock 28 spline vs Strange 33 splineGotcha! I have never used anything but 28 spline axles on an 8.5 or 35 spline axles on a 9". I didnt realize the diameter grew as the spline count grew. Learn something new everyday!
I just wasted my currie 9", was just rebuilt too...Zero track time,only street play,the gears burnt an knife edged, found the bolt-in currie 9"s are only good to 435hp...lol,my axles are being checked for twist as i type this,Now building up the unit to handle least 800hp...(more money)
Enjoy!
