BendPak and Magnum Rolling Jack Air Bag – Continental 2-Stage Air Spring for AJ6, AJ7, AJ9, AJ6000, BP12, BP-12LS, BP-12LSX
Rolling jack air bags (air springs) are the single main air actuator in center-position rolling bridge jacks, rated 6,000-9,000 lb depending on the jack. This is a 2-stage air spring made by Continental Rubber. Common failure: jack won’t lift, slowly sinks, or leaks air. The critical measurement is stud-to-stud distance; verify before ordering.

Fitment & Ordering Notes
The stud-to-stud center distance is the most critical measurement. Measure from center of each mounting hole in your jack – if it measures 6-1/4″, this bag should fit. Original bag may have bolts instead of studs; this replaces both styles. Call 866-902-6060 with questions.
