Description

Gemini Lifts 991270 Replacement Air Bag / Air Spring for Rolling Bridge Jacks

Rolling jack air bags (air springs) are the main actuator in center-position rolling bridge jacks. This is a 2-stage air spring made by Continental Rubber, rated 6,000-9,000 lb depending on the specific jack model. 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 – if it measures 6-1/4″, this bag should fit. Original bag may have bolts instead of studs; this replaces both styles. Holes may need drilling to 1/2″ diameter. Call 866-902-6060 with questions.
