Broke a stock axle @ the track; happen to anybody else? #1066291 08/31/11 12:02 AM 08/31/11 12:02 AM

I have never weighed the car, but I would guess it would probably weigh all of 3800 lbs. No transbrake, 3500 stall, 29.5 X 10.5 slicks, and I know I have less than 70 passes total on the car. It does have a spool in the 8 3/4 but I've never run it on the street; it been on the track only since I put it together. The left axle, (the one that didn't break) was twisted in the splines as well. Assuming the car led a pedestrian lifestyle before I got it, (that's what I'm told) I am just surprised that they had such a short lifespan. I have lots of friend that have been running stock axles (in faster cars) for years with no problems. Fwiw they twisted just out side of the spool. 6803111-DSC_0188wtmk.JPG (191 downloads)

They ALL twist outside of the spool(the spool holds the splines straight).... I broke a stock axle 35 years ago... I always buy aftermarket for any car with any type of slicks... my currant axles have about 1 whole spline of twist and they've stayed there.... by the way... paint a white line down the whole length of the new axles when you put the new ones in.... you will learn ALOT from that line

I also switch to 35 splines with the new axles and spools I now run a Dana 60 with the same 35 spline race axles as I started with 6 years ago in the 8 3/4 Mr.Cab Racing and winning with Mopars since 1964.

Anyway I did the same thing with a locker, I went to Strange after mine broke...

FWIW I ran 12.0's with stock rear/axles for and entire year w/ no problems 1.65 60 foot in a 3850lb car. This one has had only a few runs and 1.60 60 foot.

When is the last time you looked at the splines on either car?

Saw they were just starting to twist after 1 1/2 years racing it & street duty. It was an E-body 8 3/4 rear narrowed. Put aftermarket with a sure grip & finally a spool. IIRC in the NHRA rule book it says aftermarket axles required with a spool.
