Stronger. increased wheel down travel and the ability to wind up higher if that's your wish. They are what creates the 3" lift kit. The longer arms do enable an easier alignment - or so I'm told -and that is one of the reasons I want them - plus the added strength and down travel.
See that's what I thought before speaking to Snake Racing. They told me I won't receive any more wheel down travel, to get that I need to wind up the torsion bars in combo with the upper control arms and then install tough dog shocks, apparently my EFS shocks won't have a long enough stroke...... Sounded to me like they were just trying to sell me as much gear as possible.
