AVO is now
HAL they are now totally independent. They adjust with a turn of a little knob mounted right on the unit fir the rears and the fronts are from the tops I believe, when I go to a tubular K-Member I will swap to coil overs and the HALS but they are pricey. They do have aluminum casings and are very high quality. Front Struts are $240.00/each, and the 12 way adjustable rears are $140.00/each. the coil over kit is between $150-$170.
