Challenger RJ9-GS — 9,000 lb Air/Hydraulic Rolling Jack (General Service)

The Challenger RJ9-GS is a 9,000 lb capacity air/hydraulic rolling jack designed for Challenger 44018 series general service 4-post lifts. With a wider adjustable width range of 45 to 55 inches compared to the standard RJ9S, the RJ9-GS accommodates the broader runway spacing on general service lift configurations. Rail-mounted and foot pedal operated, the jack rolls along the lift's accessory rails to position under each axle for free-wheel access during brake, tire, suspension, and drivetrain service.

Key Specifications & Operation

The RJ9-GS delivers 9,000 lb of lifting capacity via an air/hydraulic pump activated by a foot pedal. Adjustable side members accommodate runway widths from 45 to 55 inches. The extendable lift pad arms provide precise positioning under factory lift points across a wide range of vehicles. A mechanical lock secures the jack at the raised position for safe vehicle support. Maximum air operating pressure is 150 PSI. The included FLR (filter, lubricator, regulator) assembly connects to your shop's compressed air supply via a standard ¼ NPT quick disconnect coupling.

Compatibility & Installation

The RJ9-GS is designed for 44018 series general service lift configurations with wider runway spacing. Verify your specific lift model and runway width before ordering. For standard 44018/44018E models with narrower runways, the RJ9S may be the correct fit. For alignment rack models (44018AR/44018XAR), use the RJ9A. Installation requires mounting the jack on the lift rack rails and securing with hex bolts. An internal airline kit (sold separately) is required. The RJ9-GS is sold individually.
