The 25,000-pound lift axle/suspension unit is designed for dump, mixer, block haulers, and other vocational trucks. Mono Lift 225 has fewer parts and weighs 82.5 pounds less than its previous model. The non-steerable unit can be used in pusher or tag positions. Its single-pivot design uses the company's Huckbolt-secured solid rubber monopivot bushing that can be replaced with hand tools. A Speed Set alignment feature allows ½-inch manual adjustments at the hanger—double the previous model's capability.
