Here it is all mounted. Got the rear curb weight of the truck, took off 220 pound for the 9". Minus 150 for rims and tires, that left about 616 lbs or 308 lbs per spring.. (140kg) so i layed a spring out on the ground, loaded 100kg of old batterys on the spring and measured the change in height. Stood on the spring as well, and measured that. Set the spring height based on the loaded weight guestimate and voila. Your impressed by my mathmatical ineptitude right? Redneck calculator rocks.
