The AUN 150 is a "hybrid" ramp of the AUN 200 that is used with trucks that have a shorter support base less than 98", so a perfect solution for the shorter short bed trucks. The lower ramp is cut to match the supporting surface length with the top ramp left to its overall 98" length. This configuration allows loading larger bikes that may not typically be supported by a small truck bed, has the same weight rating of the AUN 200, and can lift up to a 36" deck height. This ramp works with the full line of Neo-dyne accessories.
