Can you use a full spool with stock axels? What spline are a body 8.75 axels

30 spline. Yes, you can use stock axles, but they may break soon.

If you are going to race at an NHRA sacctioned track you will not pass tech. The rules state you need aftermarket axles with a spool.

They will never catch it in Tech, until you turn abruptly right or left, crash, hold up the show, and p i s s everyone off. Buy the spool and axles as a set. It's an investment.

If you're buying a spool. Get a 35 spline and axles to match. Moser doesn't even sell a 30 spline spool for 8 3/4 for fear of someone using stock axles in it.

If you don't break the axels you will surly twist the splines. I know I did.

If you're even remotly thinking about stepping up the power down the road build the car to handel the most you think you'll ever want to throw at it.


Spending money twice really gets old after a short while

I ran stock axels and a spool for years. Did twist an Axel a little so I replaced them and twisted one of them a little bit, it's still in there.

Thanks to all. I'll save up a bit more and do it the Safe/right way

if you're going to stay with the 8.75 as mentioned get 35 spline axles and spool. i don't believe the initial cost isn't much if any more

I agree. If your buying it all new then 35 spline is the way to go.

All Mopar 8 3/4 axles use the same spline, 30. I used a stock set of axles with a 30 spline spool in my stocker for several years, it finally broke the left axle off in the spool Luckily it happened on the burn out so I didn't lose control of the car like might have happened on the launch or down track I have also broke a stock axle that was already twisted in the splines, it broke the convex beveled posi plates in the rear end, which eventually cause me to switch to a Dana 70 rear end in that car Best bet is to save your money and buy the 35 spline axles and spool, don't forget about the need for the a steel cap on the drivers side on most high powered good hooking Mopars also and the back brace, the list goes on Best bet is to save your money and buy a custom made Dana 60 for your car
