Mine are prepped and clocked. I just wanted to know how much of a difference it was between stock arms and 3x3's. My back is shot so I need to make a softer ride. Better suspension equals better ride.

My simple mind tells me not to move the transmission back with longer arms. Moving the transmission back defeats the purpose of longer arms.


I went with even longer arms, then moved the transmission forwards as well :D
Ground clearance at the rear is huge compared to what it used to be, the departure angle has gone from about 30 degrees to more like 55.

Your back angle must be huge... Can you take a picture of your axles from the side?

It's not too bad because of the long axle length (dummy piece in here):

I wouldn't want to try it on short axles and inboard CV's though.

Is there anyway you can measure your back angle. I am just curious to compare you angle to mine.

With my 4x5 arms and the trans in stock position, I have a 14 degree back angle.

I know some people say that the back angle will not make a difference but I could not get my CV joints to handle the back angle plus a vertical angle.

Well, the angle does make a difference of course, you're still putting angle in the joint, albeit the relationship is like a sine wave compared to the angle vertically, but I can measure the angle for you tommorow no problem, frame is still in the jigs so it'll be easy.

Those arms should be pretty close to 5" longer, 4" wider, so should give a comparible result to yours, IIRC the engine is 4" forwards from where it was previously, but about 40mm of that is in the modded bellhousing.

I installed my new axles and I gained about 3 inches of ground clearance. I am running 28 degrees at ride height and Max at 33 degrees

Look forward to seeing how your turns out. Hopefully, you will not have the CV issues I was having.

It's way under the max angles for the joints, even at full droop the total CV angle is only 20 degrees (shafts are 30.5" clip to clip) - it runs out of plunge before it gets near the max the CV's will take, we used to run them at 26* and get a full season out of a set.
With the extra power we're cranking through them I decided to give them a bit of an easier life.
