new leafs/shocks

[gwstang]

I put the new leaf springs and rear shocks on the '66 today.  Took me about 3 hours to do both sides...you know work 1.5 hours go take a nap...plenty of beverages...work other 1.5 hours...piss and moan about being 55 years old rolling around on the concrete under an ancient car feeling ancient myself.  I was careful to support the axle tubes with jackstands/stands just in front of the rear wheels.  I used the big jack to hold the leaf in place until I was ready to lower it.  Still made me a little nervous because I messed around about 10 years ago replacing the rear shackles and did not account for the tremendous weight/pressure pushing on those things.  I unbolted on and it went "wham" on the concrete and scarred the crap out of me.  I realized that if my arm had been under there it would have been toast and in pieces.  Made a believer out of me.  I used these springs  and shocks.

got these for the front...after i recover from concrete burn and decrepit joints...lol

I did not have any problems getting the front bolts out of the leafs as I had done that dance about 10 years go and covered them with lithium grease so they would come out easy the next time.  It is sitting a little higher in the rear than I want, but may settle in a month or so.  I did leave everything loose and lowered the car to the ground and bounced the rear up and down a bunch of time. 
then tightened everything up and left for the car show at Flipp's.  I am so glad those air shocks are gone.  Bad idea on a '66 to try to shore up the weak springs...lol.

Come on pilgram................  

Sounds like a fun time.

Looks like those are labeled as stock height springs so they may sit a little high as that is how they were stock. What is the distance from the center of your wheel to the fender lip? how much space between the top of your tire and the fender lip?
A pic would help as 'too high' is subjective for each person. You did use stock shackles and not extended ones right?

My wife had the camera and went to visit the youngest boy in school in Mobile, or I would have taken pics.

[gwstang]

I can take a pic tomorrow of the wheel well to show.  One thing I was looking at was the shackles have another hole about 1" up from the bottom (where the bolt is now) and I assume that would lower the body an inch or so, if I moved it?

[Jonk67]

Sounds like you have lifting shackles, not sure what the correlation is for hole distance to ride height changes. Just to compare here is a pic of the stock shackles:

Here are my aftermarket shackles, notice I used the top holes which does lower the car.

[cmayna]

Yes, let's see a side view pic of the car as it now stands.  I like Marks aftermarket shackles, allowing you to do a little custom adjusting in the back.

[Jonk67]

Mark, it's hard to tell, are your leafs mideye or reverse eye? Mine are mideye.
I'll try to remember to measure the distance between mounting points on my stock shackles tonight.
I agree with Craig (what did I say?) I like the option you have to make small ride ht. adjustment with those.
Jon

[silverblueBP]

They're 4 1/2 leaf mideyes Jon.

That is what I need to do because there is another hole like yours and it should drop it a little.  Pics coming up in a moment.

Don't worry Jon, it'll be out little secret.     Meanwhile, I'm using 4.5 mideyes on both Red andShag

shot of the springs/shocks...yeah i stood on my head...lol















I had it down at the old horse barn because I finished changing the water outlet this evening and then washed the car because I am always wary of any antifreeze getting on the paint when I fill the system back up.  No more leak btw.  This outlet is more of a pointing out instead of up so I had to change the upper hose to a setup I had about 10 years ago with the coolant filter in place.  That thing sure did catch a lot of stuff, it had silicone sealant from putting an engine together back then, rust pieces even though the block had been boiled for a rebuild.  i can't wait to see what the rebuilt '90 5.0 HO has lurking in it....lol. Looks like I will have to go back to a 225 on the rear like Craig is using.  I have got to get a new exhaust next, it's just a pain to get the right headers to fit going around the aod tranny. Next project however as I have put this exaust together from pieces and bits after the new engine/aod install.  AOD is much wider than toploader btw.

Forgot to add that the front is right where I want it.  When i rebuilt the front suspension and added the disc brakes, I went ahead and did the shelby drop and used the lowering springs on the front.  I just hate that the rear is jacked up now!   
I will go ahead and move the bolt on the shackle up to the next hole tomorrow and see if that drops it enough to satisfy me.  Maybe I just need to find some "fatties" to ride in the back seat when I go somewhere....lol.

Though we have yet to see the back side of the leafs, it looks to me that you are running  4.5 or 5.0 standard eye leafs.  Not mid eye for the back side is way too high for mid eye.  Show us a pic of Shackled end of the leafs.

Third pic shows standard eye.....

Ok, finally remembered to crawl under again, my stock shackels are 3 1/4" center to center for the bushing mounts.

I didn't notice that the IAS shocks are mounted inverted with the piston down? Not sure what difference it makes either. Is that the way the instructions stated?

Well  eye yei yei....it sure does.

[gwstang]

I wondered about which way the shocks should...instructions from summit racing said they might have to be mounted up or down according to the application.  But, it didn't mention which application...lol.  Don't you just love instructions like that?     I got to studying the shock and noticed an arrow that pointed up and had this way printed beside it.  That did help a little.

I'll check the measurement on mine and see what it is,  thanks.

How about an update on the rear height? Any progress on getting it a little lower to reduce the rake?

[buening]

A little tidbit of info on the inverted shock.  If you invert a shock (and the manufacturer allows it depending on design), you actually reduce the unsprung weight of the suspension.  The same goes for coilovers.  The majority of the shock weight is in the housing, so if it is in a fixed location and only the piston and ram move up and down there is less mass being pushed by the suspension.

[CoupedUp]

Makes sense...... I installed a set of Edelbrock shocks on my Superduty a couple of years ago. Their instructions specifically asked for them to be installed in the inverted position. IIRC it had to do with the their internal design, and needed to be inverted for their valving to function correctly.
