1350 U-Joints with Transbrake ?

[Mike Gaines]

I currently only have the 1350 U-Joint setup on the rear of my driveshaft with my forged 1350 pinion yoke with my DANA 60.
I just realized that I only have a 1310 U-Joint yoke on the front of the driveshaft and a 1310 transmission slip yoke and a 1310 U-Joint setup on the front of the driveshaft.
I strongly think that I need to get a 1350 transmission slip yoke and 1350 U-Joint setup on the FRONT of my driveshaft SINCE I AM NOW USING A TRANSBRAKE AND WILL BE LAUNCHING AT ANYWHERE BETWEEN 3600 RPM AND 4300 RPM (depending on what rpm works best for consistency and 60' times.
I don't want to blow the driveshaft out...
Give me your input please...thanks....Mike

Mike,
Since you have this dread in your mind you should swap just so you can sleep at night. It will also help the economy!

just think of it this way,transbrake is like dumping a clutch,i need to do this this winter on one of my cars,get a billet yoke for the 1350 u-joint,ans spicers hi impact 1350 u-joints,but then you have to take the driveshaft and yoke to a driveline shop and have them convert the driveshaft

I have 1350 front & rear and thick wall moly driveshaft with the foot brake car. You can never have TOO STRONG of a drive shaft set up.

I had a stock drive shaft explode in my car. Never again. After that I went to the DC drive shaft kit with 1330 U joints & a Dana. Since then 1350 chrome moly shaft with forged yokes.

Heck Mike, if you are going that far get a carbon fiber shaft too ! My neighbor just bought one and man it is light and is said to be 10X stronger the any metal shaft. Just a thought ..

I had one come out of the hemi, cut the right rear slick and destroyed the 727 . Think GOD straightened it up, I couldn`t!

Mike this is one area I tend to be cautious in. I got by for yrs w/the small front ujoint and the combo 7260/7290 on the rear of my cuda. I was lucky. Low tens at 3500lbs but that was foot braking. After seeing several racers brake their ujoints I went w/1350 at both ends and a billet yoke in my wagon.
To me its a no brainer stepping up since you have a trans brake,

Heck Mike, go carbon fiber, 1350 joints, billet yoke & slip spline. It's only money. For sure do the 1350 joint.

One comment. A brake is not "as" violent as a clutch as there is some pre-load on the drive train when the brake is applied and the converter stalling. It's still violent but I don't think as bad as clutch/manual.

I think you are wrong. In my limited experience and watching others, brake applied before going up on the converter.

A torqueflite with a trans brake button on is in drive and reverse at the same time which keeps the car from rolling. My GTX might not hit the tires as hard as "side stepping" a clutch but it will carry the front tires and 60 foot in the low 1.40's.

Tempest, I have to disagree with you as a torqueflite, when the trans brake is applied is in drive and reverse which keeps the car from moving. We use the brake to stage the car after the pre-stage light is on. This in turn cause the car too settle and unloads the suspension.

I have a steel shaft and 1350 joints in my ride. Also, both yokes are billet. Seems to be working just fine.

Elaborate on this a little more please.

Where can you get a 1350 u joint slip yoke for a 727?

When the trans brake is engaged,1st & reverse are applied at the same time so NO LOAD like when foot braking.So when you let go of the TB button it's like side stepping the clutch at a lower RPM.

They are available from many sources. I got my last one through Mancini.

Thanks, Does it really matter which brand/material used? Chrome Moly the best?
