Challenger Rolling Jack - RJ9S 9,000 lb Capacity for 4-Post Lifts
If you're still dragging out a bottle jack every time you need to pull a wheel or get under a vehicle on your 4-post lift, you already know how much time that wastes. 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.
Width-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.
This 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.

Installation & Setup
Setup is straightforward if you've got shop air available. The jack ships with a pre-installed FLR (filter/lubricator/regulator) assembly. You'll install a 1/4 NPT male quick disconnect coupling into the air inlet and match it to your existing shop fittings. From there, place the jack on the lift rack rails, center it between the runways, and lock it in place by tightening the four hex bolts (two per side).
Before you put it to work, run it through a couple of lift cycles to get familiar with the controls. 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. Daily inspection for wear, damage, and air/hydraulic leaks keeps it running reliably long-term.
Compatibility note: The RJ9S is designed exclusively for the 44018 and 44018E series 4-post lifts. Runway spacing must fall between 33-15/16 and 41-11/16 inches. If you're running the 44018AR or 44018XAR, that model uses the RJ9A variant instead.
Applications
Replace the bottle jack shuffle with a tool that stays on the lift. Faster wheel pulls, brake jobs, and suspension work when you're running multiple bays at volume.
The adjustable arm span handles the range of vehicles coming through a busy tire shop without swapping equipment between jobs. Width adjusts to reach manufacturer-specified pick-up points accurately.
High-cycle environments where a rolling bridge jack for 4-post lifts pays off fast. The air/hydraulic operation keeps the pace up when you've got multiple vehicles queued.
When you need precise lift placement to hit manufacturer pick-up points on performance vehicles, the controlled hydraulic lift and adjustable arms give you the accuracy a floor jack can't.

Frequently Asked Questions
Which 4-post lifts is the RJ9S compatible with?
The RJ9S is built specifically for the Challenger 44018 and 44018E series 4-post lifts. 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.
Do I need two rolling jacks, or will one work?
One 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. When using two jacks together, the capacity of each jack should not exceed half the total runway capacity of the lift they're on.
What's the maximum lift height off the runway?
The RJ9S raises vehicles from a minimum of 3-3/4 inches to a maximum of 13-5/8 inches above the runway surface. That range is enough to handle wheel, brake, and suspension work without requiring the vehicle to be at full lift height on the 4-post.
What air supply does this jack require?
The jack uses shop air through a 1/4 NPT male quick disconnect fitting that you'll install into the pre-mounted FLR assembly. Maximum operating pressure is 150 PSI. The FLR unit (filter, lubricator, regulator) ships already installed on the jack, so you're just matching to your existing shop air fittings.
How wide does the arm span adjust?
The arms extend from a minimum of 33 inches to a maximum of 50-3/16 inches. That range covers the pick-up point spread on most passenger cars, light trucks, and SUVs. Stack pads are included to help reach lift points on vehicles with higher underbody clearance.
Does this come with a warranty?
Yes. The RJ9S is covered by Challenger Lifts' warranty for 1 year on labor and functional parts, and 1 year on structural parts. The warranty applies to the original purchaser only and requires proper installation and use per Challenger's specifications. Warranty registration may be required after purchase - refer to the included documentation for details.
Does the rolling jack ship for free?
Yes, free shipping to the contiguous lower 48 states. This is a freight shipment. If you need a specific delivery window, liftgate service, or residential delivery, contact us at (855) 498-2147 before placing your order so we can confirm the right delivery setup.
What maintenance does the RJ9S require?
Daily: inspect the jack and components for damage or wear, and check the air/hydraulic system for leaks. Check the in-line lubricator oil level each day. Annually: check the hydraulic pump fluid level with the jack fully lowered by removing the breather plug - oil should be at the top of the filler plug hole. Keep the jack free of corrosive agents and solvents to preserve service life.
