I have about 500 hp, T5, Drag Radial and a 2980# car with driver. Will strang or moser 31 spline axles handle a 4000-5000 RPM launch?

My stock axle lasted the whole season launching at 3600 rpm but I broke it when my rev limiter did not hold my rpm and I let the clutch fly at around 6000 rpm.

I was palnning on buying the 33 spline spool package but a 31 spline setup has fallen in my lap and the money could go towards a better transmission.

Thanks for your input.

Are the axles you are looking at buying new?

I have personally seen a 31 spline handle more than that

I was going to buy new 33 spline kit but this rear with the 31 spline is coming at almost no out of pocket money.

I have 31 spine mosers in my car (in avitar). I have went 5.60's in the 1/8th leaving on NOS weighing 3100lbs (had to add weight for the nos) a few years ago with no problems. 60ft in high 1.20's to lower 1.30's. I have also left at 6000rpm on the break with no nos at 2800lbs, 1.24 60 ft.

ok, where I was going is this:
I have seen axles break due them having taken a "set" at a certain load or twist amount. Combination changed and load increased and the axles break. Replaced with same components and lived forever. Did I explain clearly? If you are buying used axles that were in a higher horsepower/shock load combination, transbrake/clutch you should be fine.

Thanks everyone. I will run the 31 spline and apply the money saved to a new transmission.

Yea, I went lots of 1.40's and a handful of 1.30's with 9" 31 spline axles - never hurt one until the Detroit Locker broke a drive spline and the broken spline chewed on the splines.
