rear shocks

rear shocks
I have replaced the rear springs on my 70 442 and they lifted the car 11/2" I have released all the air from the rear shocks.
Will this harm the shocks. MOOG instructed me to place 150lb of weight in the trunk for a month or two to sag the springs.
Any advice.

Air shocks or air bags should always have some air pressure in them.

I will be replacing the shocks with KYB to match the front. Not so happy with the stance but the ride quality is a huge inprovement.
When I replace the springs and insulators the old insulators were gone this may of helped in lifting the rear some.
Any body used the same springs?
Thanks gents.

It looks like some others used the CC501's...

I think Wireman134 said in another post that his car was sagging 1.5" and the new coils corrected it. Might you be seeing the same thing?
I am really thinking of going the CC501 route - I have been hearing good things about the ride quality.

Interesting...
Both were for the HD suspension.
Is the Moog 5450 the correct front spring? All that is given is "Frt Susp; w/A/C; Heavy Duty" - no body style designation. I assume this is right...

I did a lot of research on this and the '70 442 had a "Dago" rig but that's not for me ...
I can't believe I don't have a good side shot ...

There are only top insulators and the bottom of the spring has to be oriented correctly ...

I used rubber on the driver side and cut a thinner poly donut for the passenger side...
I drive my car a lot and I am happy but I plan on using "tall" spindles when I go through the front end ...

I spoke to Performance suspension and they advised me that the original springs are 6321, the heavy duty are 5385. and the progressive cargo coil is CC501.
As to the insulators, I only used them on the top and nothing on the bottom. mugzilla's pic seems to show somthing on the bottom.
Do to the ride quality being so much better with the CC501 (also replaced the rear control arm bushing at the same time) I think I will leave them and just replace the air shocks with the KYB's. The stance I will live with.
Thnaks all.

I have posted a pic in my album (haven't mastered the attachements yet) of the stance. Keep in mind I have 150LB of weight in the trunk in this pick. The frount end is all new. The rear I just completed control arm bushings and springs.
I will remove the weight and take a pic.

Since the vert is heavier (like 4-dr), it will sit a tad lower. The 60lbs of dynamat will lower it half a tad more...

On the front I use the polygraphite front end rebuild kit from preformance suspension and included the MOOG 5450 (AC car) springs with KYB shacks. The ride quality is a 100% improvement. Can't wait to get a new close ratio steering box and get the air shocks off the back.

This pic is WITH 150lb in the back. I will leave a in for a few months. Performance suspension advised me the springs will sag after 500 miles or so????
Drives like the 1970 442 i bought in 1975 (long gone)
Next on to the electrical mess the last owner made for me.

Did it include tall spindles ..?

Howdy. Very nice looking '70 you have. Where in AZ are you located?
I just replaced the springs in my '68. I ordered my springs from Fusick. They cut them to exact heighth, and mine are spot on. If yours don't drop, this might be an option.
Hopefully, I'll be back in AZ in Sept and driving my 442. Finally....

I am going to try the "tall" spindle and stock a-arm since the short a-arm will lower the front end. You have to align for the taller one...

Welcome back to AZ. I'm in the Prescott Area where it's cool. I think the springs I'm using will work for me but thanks. Post a pic of your 68.

Were you trying to sale your car recently? Thought I seen it when I was looking for mine.
