Challenger RJ9S — 9,000 lb Air/Hydraulic Rolling Jack

The Challenger RJ9S is a 9,000 lb capacity air/hydraulic rolling jack designed for the Challenger 44018 and 44018E standard 4-post lifts. The "S" designation indicates this jack is built with the side member geometry specific to standard (non-alignment rack) 44018 models — it is not interchangeable with the RJ9A (alignment rack models). Rail-mounted and foot pedal operated, the RJ9S rolls along the lift's accessory rails to position under each axle for free-wheel access during brake, tire, and suspension service.

Key Specifications & Operation

The RJ9S lifts from a lowered height of approximately 3.75 inches to a raised height of 13.625 inches. The extendable center lift pad arms reach from 33 inches (retracted) to over 50 inches (extended) for precise positioning under factory lift points. Maximum load per arm/pad is 4,500 lb. The air/hydraulic pump is activated by a foot pedal and delivers 9,000 lb of total capacity at 6,300 PSI hydraulic pressure. A mechanical lock secures the jack at the raised position. Two 3-inch stack extensions are included. Maximum air operating pressure is 150 PSI.

Compatibility & Installation

The RJ9S is compatible with Challenger 44018 and 44018E standard 4-post lifts only. For alignment rack models (44018AR, 44018XAR), use the RJ9A instead. Installation requires mounting the jack assembly on the lift rack rails and securing with four hex bolts. An internal airline kit (sold separately) is required to route compressed air to the rolling jack positions. The RJ9S is sold individually.

Frequently Asked Questions

The RJ9S is designed for Challenger 44018 and 44018E standard 4-post lifts only. For alignment rack models (44018AR, 44018XAR), use the RJ9A instead.
The RJ9S is for standard 44018 and 44018E models. The RJ9A is for 44018AR and 44018XAR alignment rack models. They have different side member geometry and lift height ranges — the RJ9S sits lower (3.75 in. lowered, 13.625 in. raised) vs the RJ9A (4.75 in. lowered, 14.625 in. raised). They are not interchangeable.
The RJ9S requires compressed air via a ¼ NPT quick disconnect coupling at max 150 PSI. An internal airline kit (sold separately) routes air through the lift to the jack positions.
The RJ9S lifts from 3.75 inches (lowered) to 13.625 inches (raised). Center lift pad arms extend from 33 inches to over 50 inches.
Yes, two 3-inch stack extensions are included. Optional 6-inch (10355-6) and 9-inch (10355-9) extensions are available separately.
