Stock spring dimensions

[Josh]

I have two springs that came with my car. I am just trying to identify if they are stock or aftermarket springs. Does anyone have the height of the stock front and rear springs?

Thanks!

Does anyone have the height of the stock front and rear springs?

Measured ours sitting in their box -

Front: 14 in.
Rear: 16.5 in.

[Josh]

Well I measured them to be 14-3/8" . Look like they are stock fronts? Or perhaps lowered rears?

Probably more important to know the "wire" diameter than the no load length.

[Josh]

I understand there is more to a spring than the length; the unloaded height could be the same as stock but the loaded could be less depending on the capacities and rate of the spring. Ill put a caliper on the coil later

Measured our OEMs sitting in their box -

Front: 14 in.
Rear: 16.5 in.

These readings are within 1/4 in tolerance in hopes of ID'ing yours.

Good point from Dave M about the wire diameters, so here you go.

Spring wire diameters for the pairs of OEMs we took off the car.

Front: 0.485 in.
Rear: 0.510 in.

With OEM coating, no corrosion. Used dial calipers.

Thanks for taking the time to measure Rich!

I got close to the same measurements, using vernier calipers. Also, they have some rust, so measurements will vary from others.

Front -

Length: 14.375
Outside Diameter: 4.475
Inside Diameter: 3.500
Wire Diameter: 0.490
Gap: 1.305
Turns: (about) 8.25

Rear -

Length: 16.375
Outside Diameter: 4.515
Inside Diameter: 3.480
Wire Diameter: 0.514
Gap: 1.185
Turns: (about) 9.9

I do not have a way of measuring the compression weight (or know the correct term for it). Hope that helps.

All DeLorean springs have a spring rate of 150lb/in (+/- ~3lbs)

If you're trying to identify OEM springs as was mentioned above the rears have a heavier wire size. Also as the pic below shows the rears will have a yellow paint smear and the fronts will have a red smear.
