So how much suspension lift are people getting from this? Trying to estimate ride height, the only stock front sprung weight I could find is ~1575 lbs, with two 170lb/in springs with 17.87" free length that comes to 13.2 inches nominal height, only 1.2 over stock.
Sure, it depends on the weight of your rig. But using the 170 lb/in spring rate given for the Pro Comps, a stock TJ would only be lifted 1.2" in the front.
What are close to stock/lightweight rigs getting up front, for example? This can be compared to the computed value to see how close the spring rate is to real averaged rate over the compression used.
I run the ProComp Springs and have a .75" spacers in front for leveling. I have aftermarket bumpers that would be considered heavy (not Chinese thin crap), a winch and a hardtop. With all that said, I sit level and the lift measures out at 2.25".
Hope that helps.
