It might require some digging but I believe I saw the 500# number in a chart comparing stock coils to different OME options.I'm wicked close to pulling the trigger on this setup. Only concern is the spring rate of the coils compared to what is on our stock vehicles. I'm not planning on a bumper, extra battery, etc in the front so I really don't feel like getting thrown around by a coil that's too stiff. Sounds like the spring rate is 650 lbs, does anyone know for sure what the stock coil spring rate is?
I agree, 650 is arguably too stiff for mostly stock weight.
