The performance springs (3inch front) have 827lbs/in spring rate, it makes more sense on a V8 GX, but usually this only effects hitting a speedbump with both tires at same time.. you get very little compression. Once skids, bumper, winch come on, it will hopefully be little more squishy.

Off road they have been great. Overall, aside from the spring rate, I'm happy
