The square u bolt sounds like a plan......I dont think the correct ones will fit with the add aleaf in there......

Just hardware store ones I guess?

Yes, the hardware store variety will work for spring clamps . You can also use two pieces of flat stock and two bolts.

Shocks, not uncommon for them to top out when the rear lifts. This is why mopar recommended and produces long rear shocks for SS suspensions. You've duplicated the SS  approach, so  you need longer shocks. Mopar makes a specific long shock for this application, or you can add shock extensions, or you can substitute a 72-92 truck rear shock.

YOU ROCK!!!!  :clapping: :woohoo: :2thumbs:

How did you know that would be my next question!

Glad you said that because I just got back from a ride and I like the xtra lift a lot.

The car no longer wallows in the rear and no longer bottoms on dips etc......it feels like it sits aggressively now.....corners and such feel fine so far....just normal road speeds.  Just me in the car this time....my guess is adding passengers will be not much different now.

Over all the ride fine...firm in the rear.  I can now go normal speeds over roads that once produced a lot of banging/wallowing in the rear....

On sudden drops it is a bit harsh and makes a bang sometimes....but not sure if thats the spare in my trunk (yet unsecured) and the crap back there moving abruptly or if its the shocks bottoming.

So the next step will be the longer shocks.....

Since I need new shocks anyways, replacing the shocks with longer ones seems to be the ticket.

I would gather that the SS shock is pricey.,...or is it?

What would the difference in the truck shock be from the SS?

I'd think that removing a short spring from each side & maybe swapping an intermediate from side to side a preferable stance could be achieved.

That sounds like it could work...

I am going to wait a bit though.....

I measured twice in two different places......first time/location it was just 3/4" difference from side to side....second location was just 1/2" off.

A big improvement over the 1" difference I was seeing in my garage.

So maybe after things settle a bit I will remeasure and see where I am at.....

I've never measured mine, but I'd bet most are out by about a 1/2". Exactly the same is probably not too common with leafs.  :clueless:

Cheap method is to flip the shock mount, swap them from side to side, and grind out the flange to allow the spring to sit flat. Kinda like this.

Mancini has the long shocks for $43. This is probably a bit higher than your average parts store Monroe gas charged, but may be a bit less than a Rancho adjustable.

All they really say is "These Mopar Performance Parts rear shock absorbers are designed with the extended length required by special drag racing applications listed below."

They really dont say by how much they are longer.

I wonder if these "Mopar Performance" shocks are really better performing shocks or just longer than usual standard shocks?   "Special drag racing applications" could mean they have poor street manners..... :dunno:

Summit shows some "dragracing" shocks, but they have a warning that "90/10 valved shocks should never be used on a street driven vehicle".  The Mopar shocks there dont have that warning, but they DO say 'for drag racing only"......  :clueless:

I just need a shock that is longer but valved normally.....

I would think the truck shock is valved more for street, but it would also be valved for a TRUCK versus the lighter car.....????

Before this length issue came up I had been considering   Bilsteins.....I got them for my Durango a couple years back and LOVE them.  But without knowing how much extra length I need I would be guessing.

Go to the parts store and buy one for a 72 - 92 truck.  Take it out and measure it, both compressed and extended.  Put it back in the box and return it.  Use those dimensions to order Bilsteins.

 :thumbsup:hej.i love pumped up rears,but i hope yours settle a bit,or buy large dia tires.about the rear shocks you could get hold on some aar/taa shock mounts,to use oem length shock with a higher rear.and as crycho said shouldnt you be able to fix those different rear measurements with the torsion bars,have you checked the front ride height by the book.or maybe that messes up the front side to side difference.and you might be on to something there with your garage floor, cause when i park my -70 on really uneven ground my car sits high on one side and low on the other to.and hej,i know there is a time difference over the continents but  :bigsmile:did santa come really early to you this year?you must have been good. :clapping:
