How strong are the Ford Racing Aluminum driveshafts?

[352Ford2]

How much power are people puting through these things?

are people twisting them up?

FMS-M-4602-G

 

[cjman15]

They are twice as strong as the stock steel driveshafts. I haven't heard any stories of them failing anyone no matter how much power they are putting down.

I've heard of a few of the latemodel cobras braking them on some pretty hard launches. That's mostly the U-joints I think however.

 

[352Ford2]

are you talking about FMS-M-4602-J or the stock cobra units (or are they the same, I can't remeber)

 

[super302]

How much power are you putting down, they can sustain quite a bit of HP

 

[352Ford2]

Around 285 NA and 400 on the bottle, it's a stick with 26" slicks too

 

[super302]

you'll be more than fine

I shattered the yoke on mine, was putting down 265/301 at the time.

Took out the tailshaft housing on the T5 too.

That yoke had to be defective or something else was wrong with installation.

was a hard 1-2 shift, had the driveshaft on the car for a good 7-8000 miles already

It matters not. Literally hundreds of folks put 400+++++ HP/TQ to those things with no problem. Someone up there noted the U-joints as the weak link. That's correct. If your using el-cheapo u-joints and the yoke breaks free then the races will likely break. If your yoke "shattered", it was defective.

never said it wasnt. Just saying what happened to me

I blew the cups out of mine (keeper springs came out) and when the shaft was bouncing around it got dented - game over and I have a new paper weight. Sucks because I bartered a $250 port job for the shaft and it happened driving NORMALLY down the highway the first day I put the shaft in.

 

[S&B]

when i had my 31 spline yoke put on, i had a high speed balance done and new u joints it was cheap.

ive put down 600++ through it so far, the guy and the drive shaft place said they hold up well, untill you start doing wheel stants and such.

you should have no probs.
