Rear Axle Under Trailing Arms - The 1947 - Present Chevrolet & GMC Truck Message Board Network

mclairmo · 07-24-2009, 02:41 PM

I was thinking of moving my rearead under the trailing arms to give me some added lift. Has anyone done this? I am most concerned about the perches welded to the bottoms of the axle tubes. I don't want to have to remove the old perches and then re-weld them to the top of the axle tubes for fear of warping the axle tubes. Any thoughts?

it would bolt up but it would extreamly throw off the pinon angle ive never seen any1 do it u would have to weld new perces on to the axle

I figure I can mock it all up and then rotate the front of the axle up a little prior to final welding to correct pinion angle. Of course, I would also measure for correct angle prior to final welding.

Don't forget to relocate the shocks. How are you going to get the front end up?
