ther has been a lot of people over the years try them, including myself, and they all took them off, including me, my thoughts are if you want more instant action in the bar use a softer spring and play with pre load, i felt with the progressive spring when the lift bar traveled through the soft side of the spring and hit the hard side, it tended to disrupt the car and kind of shock the tires. i tried about every thing and i rarely deviate from a 300# spring now, i do play with the valving of the 5th shock though. i use a regular afco oil double adjustable shock.
