Coils Prings
« on: October 04, 2020, 07:37:06 PM »
Will coil springs from a 74 or later version fit my 71, 2 lt sedan?
If so will the coils need to be cut and how many?
If later versions do not work well, are there any other models that can be made to fit with good ride height and comfort?

Any thoughts?

The later 74 up springs are too long in length and would need shorting.  If nobody here provides input, trial and error cutting coils off a 74 up spring could be done.  Also suggest contacting RacerWalsh.com as they advertise coil springs for the 71 with various spring rates.

One of the things about cutting springs is that it stiffens the rate. There are spring calculators that might be helpful to determine how much.  As it is '74 and up springs are probably rate higher because of the 2.3 engine. I don't know the cost (probably not cheap) but I believe you can have springs wound to specification.

  Somewhere (I think it was MOOG) has a chart showing all the wire diameters, coil count, coil circle diameter and free length. It might be by that process you can find a spring "close enough" for another application that can be used. Just as an example a lot of Studebaker guys use aftermarket "Cargo Carrier," variable rate, mid-80's GM FWD, REAR springs - on the FRONT of their cars. This was ultimately determined by using a spring chart and doing a comparison.

What's wrong with the springs you have?
'72 Runabout - 2.3T, T5, MegaSquirt-II, 8", 5-lugs, big brakes.
'68 Mustang - Built roller 302, Toploader, 9", etc.
