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 in-house and made from 1/4" thick steel. This listing is for a set of (2) axle stands that will come with grade 8 hardware and need to be welded. (Castors not included)
