Firestone 2" Air Spring Spacer Kit, Axel Mount 2366 15-1450

Lift spacers can be used with most Ride-Rite air helper spring kits - NOT Coil-Rite or Sport-Rite. In order to ensure proper spacer usage, determine the distance between the upper and lower brackets of your air helper spring kit, and whether the kit mounts on the leaf spring or the axle. The spacer needs to be the same length as the amount of lift applied to the axle on which the air helper spring is being installed. * Axle Mount - Lower bracket attaches to the axle. * Leaf Mount - Lower bracket attaches to the leaf stack.
