My rear springs sit fine. I just bought a 5 leaf flat spring pack for the front cause of the added weight of a winch and dual batteries. Afterwards the front sat about 1.5 inches lower than the rear. I have a 1" bl. So i thought I'd get the 1" HD shackles to lift the front and help compensate for the trac bar removal with added strenght. I hear the stock shackles are weak. It rides nice now, very happy. Nothing else is changed. My front carden looks like it aiming right up to the tcase.
