Tom Woods Driveshafts

[BigMeatsBronco]

My local driveline shop which is very reputable amongst the rubicon community here. Recently stated that they had created a driveshaft for the Bronco. It’s not on their website but I may swing by to see what the hub is about. They said they already sold 20 or so examples.

everyone wants a piece of the pie.

(Edit) Just realized they are are about 1 1/2 hours away so not too bad No shipping cost

They have a 1350 option as well.

i see that, and that's great for the 4 dr, but there is NO way that a single u-joint can handle the 17-21 + degrees the shorter shaft runs for any long-term use....and at high speed I'm sure it would vibrate...

double cardan (like Tom Woods makes) is the correct approach for this shorty. (at least with any lift)

I do find thier choice of a single joint questionable. I just want their axle end flange, I can handle the rest.

I'm considering going with the dodge flange and the 1410 sized jumbo joints...it's easier with the U60 as the parts are readily available

Excuse my ignorance. What are the 1310, 1350, 1410 capacity ratings in reference to? U- joint capacity? Any idea of the angle design limit for the single 1350 u-joints?

They refer to the size of the U-Joint. While larger #'s are larger & stronger, the 1310 will usually have more deg of angle. Some people will run the 1310's as a fuse as well.

I have 4 door 4a transfer case and sitting near SAS ride height. Maybe 1” over at most. Flange to flange my rear shaft is just over 50” long. My ride height shaft angle is close to 7 degrees. With plus or minus 5” of rear pinion up and down motion (which my suspension can’t do, only 7-8” of travel) I won’t likely see more than 12 degrees.

Curious what 2 door shaft length is flange to flange. Would like to plot this to see differences. More than 10 inches shorter will make a big difference.

I didn't measure, but it's very safe to assume it's 16.3" shorter.

thanks. Yeah that’s what I estimated straight from the wheelbase difference.

 

[Tricky Mike]

thanks. Yeah that’s what I estimated straight from the wheelbase difference.

Actually if I could math right it's 15.7

yeah. Didn’t want to point out your math might be as sloppy as mine is.
