Challenger Lifts RJ7.5 7,500 lb Rolling Jack for 4-Post Lifts
The Challenger Lifts RJ7.5 Rolling Jack is a professional-grade air/hydraulic rolling jack designed to maximize the versatility of your Challenger 4-Post lift. With a 7,500 lb lifting capacity, this rolling jack eliminates the need for awkward manual bottle jacks when accessing vehicle pick-up points for undercarriage service. The RJ7.5 features adjustable-width lift pad arms, extendable adapters, and a low-profile design that stays out of the way when not in use. Compatible with Challenger 4015, 4115, and 4P14 Series 4-Post lifts, this rolling jack is backed by Challenger's 1-Year Warranty on labor, functional parts, and structural components.
Challenger RJ7.5 Features
7,500 lb Heavy-Duty Capacity
The RJ7.5 delivers 7,500 lbs of lifting power with hydraulic pressure rated at 5,500 PSI at capacity. This robust capacity handles everything from passenger vehicles to light-duty trucks, giving your shop the flexibility to service a wide range of vehicles on your 4-Post lift.
Air/Hydraulic Operation
Powered by an integrated air/hydraulic pump system with a maximum air operating pressure of 150 PSI, the RJ7.5 provides smooth, controlled lifting with minimal effort. The foot pedal operation keeps your hands free to position the vehicle and monitor the lift process.
Adjustable-Width Lift Pad Arms
Extendable lift pad arms adjust to reach vehicle manufacturer's recommended pick-up points on a variety of vehicles. The included 3" stack pads and spacers ensure proper contact with lift points, protecting vehicle undercarriages during service.
Two-Hand Safety Operation
The RJ7.5 features a two-hand operation design that ensures technician safety during lifting and lowering. The integrated lock mechanism allows you to secure the jack at your desired working height, and the lock release handle requires deliberate action to lower the jack.
Low-Profile Design
When not in use, the RJ7.5's low-profile, adjustable height keeps the workspace clear and unobstructed. Simply roll the jack forward before moving vehicles on or off the lift, maintaining a clean and safe work environment.
Smooth-Rolling Wheel System
Four heavy-duty wheels with nylon washers and compression springs allow the RJ7.5 to roll easily along your 4-Post lift's accessory rails. The adjustable side members lock securely in place with hex bolts, ensuring stable operation during lifting.

Challenger RJ7.5 FAQ
What is the lifting capacity of the Challenger RJ7.5?
The Challenger RJ7.5 has a lifting capacity of 7,500 lbs with a hydraulic pressure rating of 5,500 PSI at capacity. When using two rolling jacks, the combined capacity of both jacks should not exceed half the total runway capacity of your 4-Post lift to ensure safe operation.
Which Challenger lifts are compatible with the RJ7.5?
The RJ7.5 is designed for use with Challenger 4015, 4115, and 4P14 Series 4-Post lifts. These lifts feature accessory rails that allow the rolling jack to mount and travel along the runways. Contact us to verify compatibility with your specific lift model.
What are the air supply requirements for the RJ7.5?
The RJ7.5 requires shop air connected via a 1/4 NPT male quick disconnect coupling. Maximum air operating pressure should not exceed 150 PSI. The jack includes an FLR (Filter-Lubricator-Regulator) assembly with gauge and fittings to ensure clean, lubricated air for optimal pump performance.
How do I install the Challenger RJ7.5 on my lift?
Installation involves three main steps: First, install the 1/4 NPT quick disconnect coupling to match your shop's air fittings. Second, place the jack assembly on the lift rack rails. Third, adjust the side members, center the jack between the rails, and tighten the four hex bolts (two per side) to lock the jack in place. Always operate the jack through a couple of cycles to become familiar with the controls before lifting a vehicle.
What warranty coverage does the RJ7.5 include?
The Challenger RJ7.5 includes a 1-Year warranty covering labor, functional parts (pump, cylinder, hoses, hydraulic fittings, valves, controls), and structural parts (jack body, scissor plates, side members, arms). The warranty requires product registration at challengerlifts.com and applies only to the original purchaser when the product is installed and maintained according to Challenger's specifications.
What is included with the Challenger RJ7.5?
The RJ7.5 includes the complete rolling jack assembly, air/oil pump with foot pedal, FLR assembly with gauge and fittings, two adjustable-width lift pad arms, four 3" stack pads, two footpads, side member assemblies with mounting hardware, hydraulic hose and fittings, and the installation/operation manual. You will need to provide the shop air supply and compatible 4-Post lift.
How is the Challenger RJ7.5 shipped?
The RJ7.5 ships via freight with free delivery to commercial addresses in the 48 contiguous United States. Lead time is typically 3-5 business days. Curbside delivery is standard, and a forklift or loading dock is recommended for efficient unloading. Inspect all packages for damage before signing the BOL.
Can I use the RJ7.5 with non-Challenger 4-Post lifts?
The RJ7.5 is specifically designed for Challenger 4015, 4115, and 4P14 Series 4-Post lifts. While other 4-Post lifts may have similar accessory rail systems, compatibility is not guaranteed. Using the RJ7.5 with non-compatible lifts may void your warranty and could create safety hazards. Contact us to discuss your specific lift model.
What maintenance does the RJ7.5 require?
Daily maintenance includes inspecting the jack and components for damage or excessive wear and checking the air/hydraulic system for leaks and in-line lubricator oil level. Annual maintenance involves checking the hydraulic pump fluid level when the jack is completely lowered by removing the breather plug - oil should be at the top of the filler plug hole. Replace any worn, damaged, or broken parts with Challenger-approved components.
How do I properly lift a vehicle with the RJ7.5?
Roll the jack forward before moving the vehicle onto the lift. Ensure the vehicle is centered on the rack, apply the parking brake, and chock the wheels. Roll the jack to the vehicle manufacturer's recommended pick-up points, extend the lift pad arms, and use stack pad spacers if necessary. Raise the jack using the foot pedal, then lower onto the lock at your desired height. Always follow the two-hand operation safety protocol when lowering the jack.
What should I do if the jack won't raise or lower?
If the jack will not raise off the locks or the locks will not retract, consult factory-authorized personnel immediately. Do not attempt to override any safety feature to lower the lift. Check your air supply pressure and connections, and ensure the in-line lubricator has adequate oil. The manual includes instructions for adjusting the release mechanism if needed.
Do I need two rolling jacks for my 4-Post lift?
While a single rolling jack provides lifting capability, many shops prefer to install a pair of rolling jacks for balanced lifting and increased efficiency. When using two jacks, ensure the combined lifting capacity of both jacks does not exceed half the total runway capacity of your lift, and that vehicle weight is evenly distributed on each jack's lift pad.
