The Challenger RJ9S rolling jack - with 9,000 lb capacity built for 4-post lifts - eliminates that completely. It rolls directly along the accessory rail of your 44018 series lift, positions under the vehicle in seconds, and lifts with air\/hydraulic operation. No awkward repositioning. No floor jack crowding the runway.\u003c\/p\u003e\n    \u003cp\u003eWidth-adjustable from 33 to 42 inches, the RJ9S reaches vehicle pick-up points across a wide range of vehicle types without swapping equipment. The low-profile design sits flush and out of the way when you're not using it, so it doesn't turn into an obstacle every time a vehicle rolls on or off. Two-hand operation is built in for technician safety, keeping the lift cycle controlled at every step.\u003c\/p\u003e\n    \u003cp\u003eThis is the RJ9S model, purpose-built for the 44018 and 44018E series 4-post lifts with runway spacing between 33-15\/16 and 41-11\/16 inches. It's sold as a single unit, and most shops run a pair to support both axles. If you're outfitting a bay where your team works under vehicles regularly, this is the upgrade that actually changes how the day flows.\u003c\/p\u003e\n  \u003c\/section\u003e\n\n  \u003csection id=\"specifications\"\u003e\n    \u003ch2\u003eSpecifications\u003c\/h2\u003e\n    \u003ctable class=\"gsg-spec-table\"\u003e\n      \u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eRJ9S\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eCompatible Lift\u003c\/td\u003e\n\u003ctd\u003e44018, 44018E (Series 4-Post)\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eLifting Capacity\u003c\/td\u003e\n\u003ctd\u003e9,000 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eMax Load Per Arm \/ Pad\u003c\/td\u003e\n\u003ctd\u003e4,500 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eRise Height (Min \/ Max from Runway)\u003c\/td\u003e\n\u003ctd\u003e3-3\/4 in. \/ 13-5\/8 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eArm Span (Min \/ Max)\u003c\/td\u003e\n\u003ctd\u003e33 in. \/ 50-3\/16 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eJack Rail Width (Min \/ Max)\u003c\/td\u003e\n\u003ctd\u003e33-15\/16 in. \/ 41-11\/16 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eBottom Clearance\u003c\/td\u003e\n\u003ctd\u003e1-1\/16 in.\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eOperation\u003c\/td\u003e\n\u003ctd\u003eAir \/ Hydraulic\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eMax Air Operating Pressure\u003c\/td\u003e\n\u003ctd\u003e150 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eHydraulic Pressure at Capacity\u003c\/td\u003e\n\u003ctd\u003e6,300 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n      \u003ctr\u003e\n\u003ctd\u003eAir Inlet Connection\u003c\/td\u003e\n\u003ctd\u003e1\/4 NPT male quick disconnect\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003c\/table\u003e\n  \u003c\/section\u003e\n\n  \u003csection id=\"whats-included\"\u003e\n    \u003ch2\u003eWhat's Included\u003c\/h2\u003e\n    \u003cul class=\"gsg-included-list\"\u003e\n      \u003cli\u003eRJ9S rolling jack assembly\u003c\/li\u003e\n      \u003cli\u003eSide member assemblies (2)\u003c\/li\u003e\n      \u003cli\u003eFoot pads (2)\u003c\/li\u003e\n      \u003cli\u003eAir\/oil pump\u003c\/li\u003e\n      \u003cli\u003eFLR assembly with gauge and fittings\u003c\/li\u003e\n      \u003cli\u003e3-inch stack pads (4)\u003c\/li\u003e\n      \u003cli\u003eCylinder with flow restrictor\u003c\/li\u003e\n      \u003cli\u003eHydraulic hose and elbow\u003c\/li\u003e\n      \u003cli\u003eInstallation, Operation \u0026amp; Maintenance Manual\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/section\u003e\n\n  \u003csection id=\"installation\"\u003e\n    \u003ch2\u003eInstallation \u0026amp; Setup\u003c\/h2\u003e\n    \u003cp\u003eSetup is straightforward if you've got shop air available.

You'll install a 1\/4 NPT male quick disconnect coupling into the air inlet and match it to your existing shop fittings.

Maximum shop air pressure is 150 PSI. Keep the in-line lubricator filled and check the hydraulic fluid level annually when the jack is fully lowered.

Your lift's runway spacing needs to fall between 33-15\/16 and 41-11\/16 inches. If you're running the 44018AR or 44018XAR, those models use the RJ9A variant instead, which has slightly different rise height dimensions.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eDo I need two rolling jacks, or will one work?\u003c\/summary\u003e\n      \u003cdiv\u003e\n        \u003cp\u003eOne jack is enough for rear axle or front axle work at a time, but most shops running a four post lift with rolling jacks buy a pair so both axles are covered simultaneously.
