Just installed a new set of CPP 4" rear drop springs. Installed the springs positioned in the same way, new KYB lowered shocks, new cups & hardware both sides. After installing everything the truck is now sitting about an inch higher on the right side. If I measure the installed springs, right one is about 1/2 taller than the other. Unfortunately I did not check the height of the springs next to each other prior to the install. Also I did not touch the stock panhard bar.
Would leaving the stock panhard bar somehow cause this affect? Or could I have a mismatched set of springs? Any ideas or suggestions are appreciated. Frustrating after all the work. Scott

Re: Drop spring issue
I'd think the stock length panhard bar would be in a bind w/4" drop springs. Looks like it'd be trying to push the rear end. The distance between the 2 mounting points changes was the truck goes up & down. The previous owner had 3" springs and the stock bar on my '71 and it seemed ok but too high. I swapped to the 4" with a 1" lowering block and an adjustable bar. Levelled out the stance but the ride is too stiff. Well,... it levelled out the stance after I cut 1 coil off the front.

Re: Drop spring issue
I know its been suggested that with a 4" drop I should install an adjustable bar so I will probably just order one and go from there. I could always remove the original bar to see what the affect is.

Re: Drop spring issue
I would pull the springs back out and measure them before I went any farther.

Re: Drop spring issue
Not sure if you got this figured out yet, but I ordered a set of front stock springs from classic parts and after install one side was higher than the other, ordered a set of moog springs and the truck was back to normal, The bad springs were the same height , but compressed differently, in short I got a bum set of springs.
