914World.com _ 914World Garage _ HELP - Rear Springs

Posted by: ajracer Jan 8 2005, 08:48 PM

Need Assistance !!

Here is the scoop; I acquired a teener from Florida last summer which included many
components necessary to do V-8 conversion and the basic kit is "Rod Simpson Hybrid"
Also included were FG flares, and these Heavy Duty Rear Springs. There are Four of
the "silver" ones which have some type of "color markings" and two of the all "black"
coil rear springs. Additional details and dimensions on the springs are as follows:
(see attached picture(s).

SILVER ------------------------------------------------------------- BLACK

Red/yellow markings painted on top of each --------------- No # or markings
12 1/8" Height -------------------------------------------------- 12 3/4"
4 1/2" O.D. Width ------------------------------------------------ 4 1/8"
0.47 " / 12mm Spring Diameter (same) ---------------------- 0.47" / 12mm

It is my understanding that a pair of these should be for the heavy duty rear
suspension which is recommended and or required with the extra weight of
a V-8. Really appreciate anyone's comments confirmation on identifying these
for me. Happy New Year 914ers.

PS New Thread Post pending on my project which includes a 1996 LT1 Chev
V-8 with "Boxster tranny" into my 1974 Florida roller; should be interesting !

there is no "standard" for colors/stripes on the springs unless you know the manufacture of the spring, and even then it might not ring true all the time....

like AAron mentioned, it'll take a specific amount of weight to compress the spring 1 inch...there are
