Hey all. Like it says. I need help. I think i got my measurements correct. I have a 2010 ecsb 5.3 with a 6l80e 2x4. Im about to lower 2 or 3inch in the back. But ever since i replaced my 3.08s with 4.11s I've had a ds wabble around 85mph. Im wanting to go 2pc ds. Do/have any of yall done the 2pc ds with a 2in or 3in lower in the rear. Ive built my x member im just waiting to get the ds to install. I can mount the x member were ever i need to. Around 32 to 36in. I can even make the mount further back if needed. Please help if possible with measurments.

I pm'd auto3k but no reply. I think we have the same set up and i know he did the 2pc ds. If anyone knows how to get ahold of him. See if u can get him to contact me please. Thanks

Lower it first then measure. Be sure to measure at ride height. Measure yolk center to center. And the farther back you can mount your cross member the better. I think mine is like 35 or36 inches before I got to close to the gas tank. Who is building your shaft? They should have a measure info sheet

 

I got the measurement sheet. Im gonna mout my x member at 35 or 36. I can build a bracket if i need to hang it off the back more if needed. Im using automotive driveline supply i think. They r in Hurst area. Sux i gotta lower the rear to measure. Then raise it back up till i get the shaft built. Then get smaller tires lower the truck then install the x member and shafts. Thats y i was tryin to see if anyone had my future setup so i could use their measurements. I can do it. Im just lazy and didnt wanna lower and relift my truck.
