I got bored at work today and started parusing the catalogs and compared these springs to 4" fronts. I came up with 300 lb/in versus 520 on the GM ones with the 44044s at 7" unloaded and GM ones with 4" unloaded. But are the same length. Do you think these springs would work? The center pin is offsetted which would get the front forward about 1.5" but are they too soft?
