Challenger RJ6 6,000 lb Air/Hydraulic Rolling Jack for 4-Post Lifts
The Challenger RJ6 Rolling Jack is a professional-grade 6,000 lb capacity air/hydraulic rolling jack designed specifically for Challenger 4P12 and 44012 series 4-post lifts. This American-made rolling jack eliminates the need for awkward manual bottle jacks by rolling smoothly along your lift's accessory rail, providing easy access to vehicle pick-up points for brake, suspension, and wheel service. The RJ6 features adjustable width arms with extendable reach and included adapters to accommodate various vehicle configurations. Backed by Challenger's 1-year parts and labor warranty, this rolling jack is built to deliver years of reliable service in professional shops and serious home garages.
Challenger RJ6 Features
6,000 lb Lifting Capacity
The RJ6 delivers 6,000 lbs of lifting capacity, providing ample power to raise most cars, trucks, and SUVs for undercarriage service. This capacity allows technicians to safely lift one end of a vehicle to access brakes, wheels, suspension components, and more while the vehicle remains supported on the 4-post lift runways.
Air/Hydraulic Operation
Powered by shop air connected through a 1/4" NPT quick disconnect coupling, the RJ6's air/hydraulic pump delivers smooth, controlled lifting action. The system includes a pre-installed Filter, Lubricator, and Regulator (FLR) assembly to ensure clean, properly lubricated air supply. Maximum operating pressure is 150 PSI.
Adjustable Width Arms
The RJ6 features extendable width arms that adjust to reach vehicle manufacturer's recommended pick-up points on a wide range of vehicles. Included lift pad adapters and spacers provide additional versatility for different frame configurations, ensuring proper contact with vehicle lift points.
Two-Hand Safety Operation
The RJ6 requires two-hand operation to activate the lift function, ensuring the technician's hands are safely positioned away from pinch points during lifting. This design prevents accidental activation and promotes safe work practices in busy shop environments.
Low-Profile Design
When lowered, the RJ6 maintains a low-profile stance that allows it to roll out of the way, providing an unobstructed workspace beneath the vehicle. The adjustable height range accommodates different service positions while keeping the work area clear when the jack is not in use.
Built-In Safety Lock
The RJ6 includes a mechanical safety lock that engages when the jack reaches the desired height, providing an additional layer of security while working under the raised vehicle. The lock release handle allows controlled lowering when service is complete.
Challenger RJ6 Applications
- Brake Service: Raise the vehicle's wheels off the runway to access brake rotors, calipers, pads, and drums without removing the vehicle from the 4-post lift. The rolling jack makes brake jobs faster and more efficient.
- Wheel and Tire Service: Lift the vehicle to remove wheels for tire rotations, balancing, or replacement. The adjustable arms reach standard vehicle lift points while the 4-post lift keeps the vehicle stable and secure.
- Suspension Work: Access shocks, struts, control arms, and other suspension components by raising the vehicle's axle or frame off the runway. The 6,000 lb capacity handles most light-duty trucks and SUVs.
- Exhaust System Service: Position the vehicle at the optimal height for exhaust system inspection, repair, or replacement while maintaining a comfortable working position beneath the vehicle.
- Differential and Axle Service: Raise the rear or front end of the vehicle to service differential fluid, axle seals, or CV joints while the vehicle remains safely supported on the 4-post lift.

Challenger RJ6 FAQ
What is the lifting capacity of the Challenger RJ6?
The Challenger RJ6 has a maximum lifting capacity of 6,000 lbs (2,722 kg). This capacity is suitable for lifting most cars, light trucks, and SUVs for brake, wheel, and suspension service while on a 4-post lift. Never exceed the rated capacity, as this could result in equipment damage or serious injury.
Which 4-post lifts are compatible with the RJ6?
The RJ6 is designed specifically for Challenger 4P12 and 44012 series 4-post lifts, also known as the Model 40 Series. The rolling jack mounts on the lift's accessory rail and rolls along the runway length. The RJ6 is not compatible with other brands or models of 4-post lifts.
What air pressure does the RJ6 require?
The RJ6 operates on standard shop air with a maximum operating pressure of 150 PSI. The jack includes a pre-installed Filter, Lubricator, and Regulator (FLR) assembly. You will need to install a 1/4" NPT male quick disconnect coupling that matches your shop's air fittings. Clean, dry air is essential to protect the FLR assembly and maintain warranty coverage.
How do I install the RJ6 rolling jack?
Installation involves three main steps: (1) Replace the oil fill plug with the included breather plug, (2) Install a 1/4" NPT male quick disconnect coupling in the air inlet of the pre-installed FLR assembly to match your shop fittings, and (3) Place the jack assembly on the lift rack rails. Before lifting any vehicle, operate the jack through several test cycles to become familiar with the controls.
What is the warranty on the Challenger RJ6?
The RJ6 is covered by Challenger's 1-year parts and 1-year labor warranty. The warranty covers defects in materials and workmanship when the product is properly registered, installed, and maintained according to Challenger's specifications. The FLR assembly is covered for the same period, provided it is not contaminated by wet or dirty air. Register your rolling jack at challengerlifts.com to activate warranty coverage.
What is included with the RJ6 rolling jack?
The RJ6 comes with the complete rolling jack assembly, pre-installed FLR assembly, lift pad arms with rubber inserts, two 3" stack pads, two foot pads, breather plug, and the installation, operation, and maintenance manual. Air supply lines and quick disconnect couplings are not included and must be purchased separately to match your shop's air fittings.
How is the RJ6 shipped and delivered?
The RJ6 ships via freight truck with free shipping to commercial addresses in the 48 contiguous United States. Lead time is typically 7-10 business days. Curbside delivery is standard, and you are responsible for unloading the equipment. A forklift or suitable lifting equipment is required. Always inspect for damage before signing the delivery receipt.
Do I need two rolling jacks for my 4-post lift?
While a single rolling jack can be used to lift one end of a vehicle at a time, many shops install a pair of rolling jacks for greater efficiency and versatility. With two rolling jacks, you can lift both ends of the vehicle simultaneously or quickly move between front and rear service without repositioning a single jack. Consider your typical workflow and service volume when deciding.
Can I use the RJ6 with a different brand of 4-post lift?
No, the RJ6 is designed exclusively for Challenger 4P12 and 44012 series (Model 40 Series) 4-post lifts. The rolling jack is engineered to fit the specific accessory rail dimensions of these lift models. Using the RJ6 with incompatible lifts could result in improper fit, unsafe operation, and would void the warranty.
What safety features does the RJ6 include?
The RJ6 includes several safety features: two-hand operation prevents accidental activation, a mechanical safety lock engages at the desired height for secure positioning, and the low-profile design keeps the workspace clear when not in use. Always lift vehicles at manufacturer-recommended pick-up points with weight evenly distributed on the lift pads.
How do I maintain the RJ6 rolling jack?
Daily maintenance includes inspecting the jack and components for damage or excessive wear, and checking the air/hydraulic system for leaks. Verify the in-line lubricator oil level regularly. Annually, check the hydraulic pump fluid level when the jack is completely lowered - oil should be at the top of the filler plug hole. Keep the jack free of corrosive agents and solvents to ensure long service life.
What are rolling jacks used for on a 4-post lift?
Rolling jacks allow you to lift the vehicle's wheels off the 4-post lift runways for free wheel access. This is essential for brake service, wheel and tire work, suspension repairs, and any service requiring wheel removal or rotation. Without rolling jacks, you would need to use awkward bottle jacks or remove the vehicle from the lift for these services.
