Anyone with a 3550 have to get their driveshaft shortened?

[nick6690]

I can't get my driveshaft to clear the pinion on my rear end when I go to put it in. I tried it with the car jacked up by the frame with the rear end hanging down and it still does it. I have a 3550 in my car and I'm thinking it might be a little longer than the t5 but I'm not sure. Has anyone had to get their driveshaft cut? Thanks for any help.

Never. I've installed a 3550 in two Fox's with ZERO issues like that. Something is wrong.

Nope. I've ran a stock shaft and my current aluminum shaft with mine and had no issues. It's not even tight.

what could cause everything to be out of alignment?

I have a 3550 with a aluminum ds and it slipped right in. car could have been rear ended in the past, but Id measure the tranny/ds combo when it was installed, then measure the "new setup" see if there's a diff

I put 3550 in my 91 and it matched right up.

No you do not have to get it shortened for sure. Do you have the engine set back at all? Adjustable lower control arms? What yoke is on it.

whats weird is i have a similar problem in my car, my DS is so tight to the transmission(TKO) that it actually ripped the seal a little bit, and when we put my buddies TKO600 in my car it wasnt like that, im gonna get myne shortened this yeard but i have asked around and i cant get a straight answer about how much of the yoke should be showing

2"

I have a stock k member, stock motor mounts, stock pinion flange, but I have J&M control arms.

The reason the drive shaft was out is because the clutch went out in my car. It was hard as hell to get the driveshaft out, I had to unbolt the lower control arms and upon doing so, I noticed the torque box on the drivers side was pretty messed up. The passenger side didnt look too bad tho. I got some battle boxes and put those in and welded up the seams around the boxes. I wouldn't think the torque box would cause the driveshaft to have that tight of a fit would it? It was only on one side too.
