Will this break my axles or differential???

[Rickyll7]

So I have whats listed in my sig, plus some 4.10 gears being installed. I dynod 292 rwhp 342 rwtq on a mustang dyno.

If I run slicks at the track with this setup, will I be safe, or should I stick with the street tires until I can get some 31 splines? Or will the street tires break my axles??? I basicaly want to know what it will take to break my axles with the setup I have now so I know what not to do.

Thanks:SNSign:

what kinda street tires?
Do you dead hook?
I ran all last season spraying outta the hole and my stock axles and diff lived. Most of the runs were on Et streets BIAS ply's.
However I've seen a stock Mach1 snap a stock axle and frag the stock diff on some 315 bfg dr's.

right now i have some 275's with 440 tread wear but will probably soon get some 285's with 300 tread wear, probably some eagle f1's or some nitto 555 streets

btw, what is dead hook??? I dont go to the track much...

dead hook = Hook no spin low 60' times. Normally seen on slicks or people with Dr's that have really learned how to drive them. everyonce in awhile you'll see someone do it on streettires that have mastered the art of hard launching on streettires.

For safety concerns I'd do the axle upgrade. IMO Dr's or any radial tire that hooks puts a harder shock on the rearend compents, than a bias ply tire. Of course the flip side to that is the bias ply's don't ride as well wallow more in the turns and wear out QUICK if driven on the street.

if sticky tires/DR's are used in combination with a drag launch, there will eventually be an issue with 4.10's. street tiress will light up very easily.

got mine installed last week

i would upgrade to a 31 spline setup if you do plan on using slicks or DR's just for assurance purposes

 

[hognutz]

simple answer is yes you could damage something.

I would upgrade becasue sometimes you can damage the housing itself buy spinning the tubes.

1. 31 spline axles
2. diff
3. weld tubes
4. weld torqu boxes probably.

I have read if you run reallly good control arms (no poly bushings) the torque boxes may not be a must but I would proably weld them anyway.

1+ for the rear end differential cover

On street tires, you should be fine....and if you run some nitto DRs on 15 inch rims ( NOT 17) then you should be ok also. 17s dont have much sidewall flex, so they put ALOT of load on the axles.

I thought lower the tread wair # the stickyer the tire just wairs faster?

CORRECT!! ur right but unless a company is able to make a long lasting sticky tire which some have most of the sticky tires will be low tread wear.

Get some 15" rims with DR's. If the axles snap, put some Moser's in there and a new diff
