Challenger Lifts RJ9-GS - The Rolling Jack for 4-Post Lifts That Actually Belongs in Your Shop

If you're running a Challenger Lifts four-post lift and still reaching for a bottle jack to get under a vehicle, you're losing time on every single job. The Challenger RJ9-GS is a 9,000 lb. rolling jack for 4-post lifts that slides directly onto your lift's accessory rail and lifts vehicles cleanly from beneath - no awkward repositioning, no fighting with a floor jack in a tight space. It's the accessory that makes your four-post lift worth its footprint.

This is an air/hydraulic rolling lift jack with adjustable width, so you're not locked into one vehicle profile. The extendable width and included adapters let you reach pick-up points on a broad range of makes and models without improvising. Low-profile height when retracted means it's not in your way when you're not using it - the workspace stays clear.

Two-hand operation is built into the design, which keeps your techs working safely without adding steps or slowing things down. Pair a set of these with your challenger auto lift and you've eliminated the bottle jack entirely. That's the version of your shop that runs faster and cleaner.

Applications

The RJ9-GS fits into shops that are serious about throughput. It's not a one-task tool - it covers a wide range of service work once it's mounted to your four-post lift.

Brake and Suspension Service

Roll the jack into position, lift the axle, and your tech has full access to calipers, rotors, control arms, and more - without repositioning a floor jack mid-job.

Exhaust and Undercarriage Work

The rolling bridge jack for 4-post lifts gives you a stable, elevated work surface. Exhaust swaps, transmission drops, and driveshaft work all get easier when you can control ride height precisely.

Alignment Prep

Lift individual corners of the vehicle for tire rotation or pre-alignment work without lowering the whole car off the lift. Keeps the job moving.

General Lift Support

Any shop running challenger automotive lifts for high-volume service work benefits from rolling jacks that eliminate the time lost to repositioning manual equipment under every car.

Frequently Asked Questions

Will the RJ9-GS work with my existing Challenger four-post lift?

The RJ9-GS is designed to roll along the accessory rail on Challenger four-post lifts. It's a direct Challenger Lifts accessory, so it's built to integrate with their four-post lift line. If you're unsure whether your specific lift model has the compatible accessory rail, call us at (855) 498-2147 and we'll confirm before you order.

What is the weight capacity of the RJ9-GS?

The RJ9-GS has a 9,000 lb. lifting capacity. That covers the vast majority of passenger cars, light trucks, and SUVs you're likely servicing in a shop environment.

Does the rolling jack require shop air to operate?

Yes. The RJ9-GS is an air/hydraulic unit, so it requires a compressed air supply to operate. Make sure your shop air system is accessible at your lift bay before installation.

Can I adjust the width to fit different vehicles?

Yes. The RJ9-GS features an adjustable, extendable width and comes with adapters to reach vehicle pick-up points on a range of makes and models. You're not locked into a single configuration.

Do I need to buy the rolling jacks in pairs?

The RJ9-GS is sold individually. Many shops do run a pair to support both axles simultaneously, which makes brake, suspension, and undercarriage work significantly more efficient. Call us at (855) 498-2147 to discuss your setup and we can help you figure out what makes sense for your workflow.

What's the warranty on the RJ9-GS?

Challenger Lifts covers the RJ9-GS with a 1-year warranty on labor, 1-year on functional parts, and 1-year on structural parts. The warranty applies to the original purchaser only and requires proper installation and maintenance per Challenger specifications. Warranty registration may be required after purchase - refer to included documentation for details.

Does this ship free and how does delivery work?

Yes, the RJ9-GS ships free to addresses in the lower 48 states. Our team handles freight coordination. If you need a specific delivery window, liftgate service, or residential delivery, contact us before placing your order so we can set up the right delivery and confirm any applicable accessorial charges.

Is the low-profile design actually useful when the jack isn't in use?

That's the point. When the jack is retracted, its low-profile height means it isn't blocking your view or creating an obstacle under the vehicle. You can leave it on the lift rail and it stays out of the way until you need it - no lifting it on and off the rail between jobs.
