Do these helper springs lift the height of the vehicle?
This helper spring is designed to engage when the spring starts to flatten out. It then will transfer the excess weight onto the overload. It will not lift the vehicle any higher than stock height, just keep it from sagging up to an extra 2500 lbs.
does this price include two sets of springs and all mounting hardware
