Driveshaft Diameter

[foofinator]

Hey fellas,

I am working with Inland Empire Driveline to make a custom driveshaft for the Cobra in order to complete my Magnum T-56 swap.

I was told for 1,000+ rwhp, I should go with a 4" aluminum or a smaller diameter steel driveshaft.

Will a 4" driveshaft fit underneath our cars? I would prefer to stick with aluminum, but I can't seem to find any information on this.

Thanks.

The OEM Cobra shaft is 3 1/2" dia. I don't think you will have any problem going with a 4" but I have never heard of problems at the power level stated with the stock shaft. Just shorten the one you have you should be good to go.

That's what I'll do, and then I will never have to worry about it.

Good man, moved to Austin for a job and have been working. Bought a 2015 GT and Focus ST daily, other than that, there hasn't been too much car activity. Would love to make it back to Dallas for a meet sometime, but I heard the Coit/190 meet was shut down.

How have things been for you?

Doing well. Got the wife a 16 EcoBoost Mustang. My car is stil running great.

Yeah, bunch of ricer kids messed up the meet. Need to find another location.

Let me know if your ever up this way.
