Freightliner Suspensions
FAS Airliner Truck Suspension
The list below shows replacement parts for the Airliner air spring truck suspension that is found on Freightliner and Western Star trucks and tractors. The parts below are currently in stock at Plaza.
If you are having a problem with the spring eye bushing, Atro has the solution. Problems have been reported with the spring eye weakening and enlarging allowing the bushing to “walk out” of position. Freightliner has recognized the issue and recommends their fix, part number RB268. However Atro improved on that solution further by offering their part UB20500-OS, an oversized, anti-walk bushing that takes up the gap in most enlarged eyes. If the spring eye has not yet been enlarged, Atro recommends its part, UB20500.
