So I've removed the rear springs( original and never been off the car) as I want to replace with new ones which I have ordered and received from Mopar Parts Warehouse as they were a better price but the same p/n as what Mancini lists on their website. HD stock springs( Pass side has the 2 extra 1/2 leafs). When I lay the NEW ones side by side, the pass side is at least 1 inch or more higher than the drivers. If I stand on it, it does compress down to the same height as the driver side. I finally removed the old springs yesterday and removed the front hangar brackets today. I laid the OLD ones beside the NEW ones and both driver sides are the same height, and the OLD pass side is the same height as the OLD driver side. The NEW pass side is still at least an inch or more higher than the others.

Opinions as to if that new one will settle down once installed and gets weight on it or should it be re-arched to match the others? Equipped from the factory with the Performance Axle Package which included the Hemi suspension according to my Code Book.
Thanks
 
Put them on and give them some time. I hear some people raise the driver side torsion bar to transfer weight but I would drive it for awhile. You could throw a dead body in the right side of the trunk LOL
 
as said install and see where it is . then as time passes they will settle and then you can say good or bad.
 
As stated above, install them and then put some miles on them. I installed new ones and am very pleased with the final result.
 
I know this is older post but how did they work out? I'm about to install the same ones.
 
It is to offset the torque which will raise the right hand side from the actual torque of the engine. If you add spring clamps to the front (forward side) side of the leaves, on both sides you will create de-facto traction bars and if you raise the snubber to where it contacts the floor pan at launch, you will get unbelievable launches. This is a trick I learned from the "RAMCHARGERS" as well as from Eton Eckstrand of "LAWMAN" fame. He left the "RAMCHARGERS" and went out on his own. He was a Chrysler lawyer. This was in the early 60's, liike 64-65. Air shocks in the rear help with the right one with more pressure.
 
I forgot to add that 90-10 shocks on the front complete the package. I am restoring a '70 Road Runner and I am refining a lot that I learned from racing my 1968 roadrunner in the 70's. I only have a 2 car garage so I do not have a lift or other abilities.
