[DeTomaso] Aldan shocks help!

[Ken Green]

I think Ted Mitchell has done all the hard part.  Looking at his specs:
 
552 pounds front sprung wt. per wheel
 
motion ration of shock is 1.486
 
force on the shock is 821 pounds
 
so, if you have 400 Lds/in springs, the front spring will compress just over 2 inches from the weight of the car.  If the spring is relaxed on the shock, then the weight of the car will also compress the shock just over 2 inches.  

The Aldan 755 is 15.5 inches, so if you compress it 2 inches, you're at 13.5 shock length, which is very close to having the lower control arms horizontal (Ted says static front shock length is 13.683 inches).
 
Based on this, it would be hard to lower the car to have horizontal lower front control arms with greater than 400 pound springs on Aldan 755 shocks in the front.

I'll leave that to Jack DeRyke or someone with more experience.

Mike,

     The 755s are compression, rebound, and height adjsutable.  The 800
series are compression adjustable only and the 600 series are rebound
adjustable only.  The 655 is just slightly shorter than the 755, I assume to
make room for the rebound adjustment.  The 658 uses a 12 inch spring and
overlaps the range of the 755 (a little more on the long end). 

    What would be great to know is what ride height range results from
different spring weights in the front and rear, especially with heavier
springs which may limit the ability to lower the car.

I have the 755's which you'll have to ask the rep how they compare.  One of
my goals with the Aldans was to lower the car to the proper ride height.
These worked fine.

Folks,
The guy at Aldan wasnt sure if I should get their 658HP or 655HP
shock--Wants me to measure original shock on car.  This is for a rebound
adjustable shock with poly bushings $400 a set.  Any suggestions on which
one I should get?  I understand ride height is the difference.  My car is
stock 1972 with original front shocks, not a race car!. 
Thanks in advance for your advice.
