I finished installing new SS springs on my '68 Charger, and now it is 2" higher on the right and 4" higher on the left  . I didn't expect the left to be higher. The right spring has more leaves and for some reason the left is higher. I have read this could be from bad quality control in Mexico. I installed them with stock shackles (currently vertical when on ground), 2" SS front hangers (used bottom hole), stock shackle mount, and no pinion angle shims installed yet. All bolts are currently loose to ensure no binding. The right (passengers) side spring part number ends in 454 and has 2 more short springs facing forward. The left one is stamped 45X but the MP sticker says 455. Did I get bad springs? Should I move the springs to the top hole on the hanger? Should I change to 1" longer shackles when I do this? Thanks Moparts Members!

I put SS springs on the back of my Valiant 5 years ago. It's still a bit higher on the left. I can't tell you how many times I have been under the car checking the part numbers. Got it right the first time and I really don't have an answer for you. I am thinking of switching to the XHD springs or maybe even the Hotchkiss for my application.

Per Doctor Diff's advice, I simply used two left-side SS springs in my a-body with a 1 inch lowering block. Sits level, rides great, handles excellent and they haven't really settled in 4+ years. I added a rear swaybar and Koni's too.
Compared to some systems out there, it was a reasonably inexpensive upgrade over the tired stocker rear suspension.

Those sure are some long shackles! Looks kind of like the Death Proof Charger...one of my buddies has a '69 with the same shackles - Mr.Gasket's I believe. First thing he did was adjust them to stock height and cut off the bottoms.
Monoleafs would of been nice. I just wanted something that would hook better and that I wouldn't get obsessed with adjusting - so SS filled the bill. Once I get the left side down a bit I will be happy. If the right was higher I would be happy because at least I understand how it helps traction. What I have should actually hurt traction. My '68 Charger has 4.10s, 3200 stall, .509 292 cam, solid motor mounts, and 10.5" tread in the back and 6" in front on ConvoPros. Since I am going for the '60s somewhat drag look I am actually like some rake, but prefer not to see the shackles. Thanks for the input. I think I will go stock R/T on my '70 AAR clone.

Per the pic above, that won't work on an E-body....Hits the valance. Not to mention super stock springs all suck. My car was horrible with them and I believe they are all chinese junk now a days. Go with Split Mono's and don't look back.
Solution:
That's actually incorrect. A pair of same-side SS springs will work on an e-body with a stock rear valance using either the stock rear hangers or Dr Diff's 1" inset hanger kit I've had them on my e-body. I'm not 100% sure about the Mopar Performance inset hanger kit, but I believe that would fit too.
I didn't use the 1 inch LOWERING BLOCK on my e-body, but that doesn't affect the fit or the rear of the spring or hanger and would work too.
Longer rear shackles may hit the stock rear valence. I think that might be what you are referring to. I never commented on those however.
I'm sure not all SS springs are bad. Many sets continue to work well when used in the proper application. They work excellent in my a-body and have held up well over nearly five years with little or no sagging.

There is something about the front spring segments being available in two lengths. One is shorter and must be used with a different front spring hanger, but I don't have the specifics at hand right now. One of the resident experts will likely update this info, or give Dr Diff (Cass) a call.

That's right. I read in the Tech Archives that the front spring segments are 2" shorter than stock B/E body springs and therefore the 2" longer hangers must be used. I did install the SS hangers with the bottom most hole used.

Every set of SS springs I put on the cars sit uneven. I just adjust the front torsion bars to get it where I like and they all seem to work and hook fine. Ron
Good deal. I may just see how I like the stance with the 1" higher hole used on the hangers. Other than pinion angle do I need to change anything else when I use this hole? Do you personally use a rear end snubber? Thanks 383man.

That's right. I read in the Tech Archives that the front spring segments are 2" shorter than stock B/E body springs and therefore the 2" longer hangers must be used. I did install the SS hangers with the bottom most hole used.
They are essentially A-body springs with a 20" front segment although '63 only B-bodies used a 20" front segment as well. Later B/E use 22" front segment thus the need for longer hangers with SS springs.
