All dimensions shown should be considered as "zero load" on suspensions, without weight of trailer or cargo. Allow 1.5" deflection at rated capacity of spring for approximate full load dimension and 3" above tires beyond that point for "maximum bump clearance." For best suspension performance, allow 2-2.5" clearance above top of axle to bottom of frame. Use of "bump stops" are recommended above 2.5" clearance.
