Our adjustable axle stands were designed to accommodate a 33-to-44-inch "tire size" ride height. These axle stands have an 8x170 and 8x6.5 bolt pattern. These are laser cut and MIG welded in-house and made from 1/4" thick steel. This listing is for a set of (2) axle stands and will come complete with hardware and castors. We also sell these in a DIY style if you prefer to weld them on your own. These are located in our accessories section.
