View Full Version : Rear Axle: Looking for Dana 44 TT rear end

03-10-2015, 07:44 PM
I just had a new exhaust system put in the Hawk and while looking around under there I made a disconcerting discovery. It seems that at some time the rear end was changed and a Dana 27 TT was put under it. I suppose with the light use it has survived but I am guessing that there is quite a difference in the original Dana 44 TT and this one. I am wondering if anyone in the Pacific Northwest might have a Dana 44 TT for sale? If so let me know.

What gear ratio?

I am running a 700R4 transmission, and the Dana 27 is a 3.01 so anything around a 3.31 would be great.

The driveshaft lengths are different.

I am running over 350 HP and am sure the Dana 27 won't last long so a change in drive shaft length is the least of my worries.

seeing as how you have already modified it why not get a ford 8.8 rear and get posi. and disc brakes at the same time.

I have a 4:27 ratio non TT dana 44.. Or you might check with Ernie Smith (owner of Tacoma V-Twin Harley) He is liquidating his late fathers Stude collection.

Thanks MChance but I think 4.27 ratio would be a bit much with the automatic transmission.

I installed a Dana 27 TT 3.01 in my R-2 Avanti on purpose for 2 reasons. I wanted better gas mileage from the 3.01 ratio and I wanted the better ride quality of less unsprung weight in the rear. You might was to consider keeping what you have with a Dana 44 as a backup. That is what I have done. So far the 27 is holding up fine, but then again, I do not unreasonably punish the car when I drive it. With 350 HP you may be different.

Don, Ernie just posted the Stude parts collection I was talking about on Craigslist. apparently he has 7 rear ends. you might give him a call

Thanks, I will contact Ernie. I might also consider leaving the 27 in for a time since I actually don't get on the car all that much. The 350 Hp is mostly for bragging rights. : )

How hard would it be to convert a late model dana 44 out of a Jeep ? They are coil spring and 59 inches drum to drum .
