I love my marlin springs, they are super flexy on the trail and okay to drive on the road...I also have 37s on the 5in springs, but mine rub on the firewall at full lock and stuff. But my tires are 13 inches wide, and for some reason I dont think a 12.50 would rub, but im not positive on that...
Oh and mine didnt settle very much at all!!
