advice on +1" leaf springs
« on: July 11, 2012 - 11:07:11 PM »
Howdy guys,
It's time to replace the leaf springs in the 70 Chally and after doing a bit of research online and on here, I'm at a bit of a loss on where to look.
I'd like some factory'ish spring in a +1" ride height, reasonably heavy duty but its a 318 car (if that matters).
Does anyone have any recommendations? Most of the 'search' items I found a quite old and there didn't seem to be a whole lot of consensus.
Cheers!

Espo is good but it is hard to know how high the rear will sit @ + 1
 Summit has springs also but no clue on those yet either

Maybe you can look at having your originals rearched,, or,do an add_a_leaf if your looking for a little more height on the rear.

  I went with Espo springs at 1" over stock height. It gives my car a nice drag race stance/rake to it, but the back end is not overly high.  My battery is also mounted in the trunk. Been on my car for three years or so with no problems.  Would definately recomend them.

I vote  ESPO . Thats where I got mine. I asked for plus 1 1/2" over stock. The ride was fine. I wanted the bum a bit high as I didn't particularly care for the stock saggy bum look? But thats just me.  Keep in mind all spring do settle a bit in the first weeks/months? First picture is when they were first installed , second picture is a month or so latter.

Thank you guys for the reply, looks like ESPO is the overwhelming best option.
Both of your cars look amazing, if my chally comes out looking similar to either, I'll be very happy.
Cheers!

Good timing for this topic to be disussed....  :2thumbs:
Thanks to this board I ordered my 6 leaf 2" over yesterday...from ESPO.

 BTW what is stock ride height for non sagging OEM springs?
...guess one has to measure from fender arc to wheel centre to rule out influences caused by tire outer diameter....
Anyone???

Factory never quoted rear ride height figures, only the front. In their factory installed height, they should only have a couple inches of arch to the leafs, max. Mopars never had high arch rear leafs unless you swapped the stock units out for Super stock units

good question on the stock ride height , mine was very firm & was very low to the point where it sat nose up unless the headers were dragging on the ground , the challs always seem to sit low in the back & +1 would be just a slight rake not raised as much as brads is at + 1.5", brads looks closer to + 2.5 or 3 to me

I jusy installed a set of hyperco composite springs. Does this look closer to stock ride height?

or,do an add_a_leaf if your looking for a little more height on the rear.

Thats what I ended up doing....as I recall, took one of the half-springs out and added the add-a-leaf.....

Brought the butt end up a bit....went with longer shocks.

I was worried at first but man, I have really gotten used to the rake and the ride, which ,combined with the 1"t-bars and a huge sway bar up front, it rides fine.....corners great.  Very firm.

Brad it looks closer for sure but still up a little , do you have a taller tire on  the rear ?
looks like it moved the diff rearward approx 1" as well

255/60/15 n the rear. I used SS spring hangers and the advertized front segment on the springs is 20 1/2" so it's supposed to be only 1/2" further back than stock?
Wow still up a little? I'm having a bit of a hard time with getting used to how low it is now!  :lol:
I'm planning on 295/50/15 as soon as I burn these off.

Well, I installed my +2" rear springs.
I am somewhat dissapointed, as there was only a marginal increase in height.
Not knowing the full history of my car, who am I to argue that my old springs was at original height ?
Does this look like +2" lift to you guys?...
... I was kind of hoping for more lift...??

But then again, if comparing to the Challengers shown on this link mine seems OK.
Are really these cars http://www.allpar.com/model/challenger.html   at standard ride height???

Here's mine with 2+ over stock height.

For reference, I have 15" wheels. 255/ 60 series, so about the same stance as your's I would say.
