REAR INSTALLATION
SUPPLEMENT FOR MOUNTING AIRSPRING ON TOP OF LEAFSPRING
1. This installation is performed with the vehicle at ride height. When you raise the vehicle to a
comfortable working height, support it by the axle housing.
2. Attach the lower airspring bracket to the top of the leafspring, preferably behind the rearend, using
the attachment hardware provided. On some models, the lip of the airspring bracket will locate in the
axle plate.
NOTE: On some vehicles, a softer ride is obtained by removing leafs from the spring
pack. Be sure to leave at least 2 leafs in the spring pack for stability.
3. Attach the airspring to the lower bracket.
4. The upper bracket can now be attached to the airspring and its placement on the framerail can be
determined. If the leafspring is under the frame, the upper bracket will be a “J” shaped piece that the
airspring screws into. If the leafspring is beside the frame, the upper bracket will be an angle bracket
that will bolt on to the frame. Using the proper inflated dimensions, check for airspring clearance to
nearby obstacles. [Refer to the airspring dimension chart.] Note that the proper inflated dimensions
will not be the same as the uninflated dimensions.
5. Mark the bolt holes for drilling or clamp in place to weld.[Remove airspring before welding to avoid
weld splatter damage!]
6. Reassemble, inflate, and re-inspect for proper clearance.
NOTE: On the 88 -99 GM 1 ton chassis the F6957 airspring should be placed BEHIND the axle
for the best clearance and the most load capacity.
REMEMBER: THE AIRSPRING BELLOWS MUST NOT TOUCH ANYTHING AT ANYTIME!! IT IS
THE FINAL RESPONSIBILITY OF THE INSTALLER TO DETERMINE ADEQUATE CLEARANCE.
PLEASE CALL AIR RIDE TECHNOLOGIES IF YOU HAVE ANY QUESTIONS.
