Spring dimensions? I know it's an odd question... but just wondering if anyone knows the free height of the stock springs and the I.D.? Also curious as to what the stock rates are. Can't say that I forsee the available funds for springs soon, but it's still been on my mind recently. Thanks!
Do you mean for your car, front or rear?
Front diameter on bottom is 3.5". Top diameter is 2.25". I don't know the free length.
Rear diameter on bottom is 2.25". Top diameter is 4.25" or a tad smaller like 4 1/8". Keep in mind the free lengths can vary in the rear depending on how many coils there are. GM made at least 2 different springs in the rear for the V8 4th gens. They both have the same ride height and spring rate but one has 9 coils and a smaller diameter wire, while the other has 8 coils and a thicker wire diameter. Free length is 15" on the 9 coil.
Rates are 292lb/inch linear front and 114lb/inch linear rear.
Hope that helps.
