Ranger RFJ-5000HD 2.5-Ton Heavy-Duty Commercial Grade Floor Jack
The Ranger RFJ-5000HD is a commercial-grade floor jack that combines strength, precision, and usability under heavy shop conditions. Rated to lift 5,000 lb (2.5 tons), it is engineered to manage the demands of shop traffic, performance vehicles, and repeated cycles without sacrificing reliability. The frame and components are rugged steel, built to withstand years of use in an environment where failure is not acceptable.
One standout feature is its extremely low profile. When fully lowered, the jack’s pad sits just 3 inches above the ground. This allows it to slip under vehicles with minimal clearance—sports cars, lowered chassis, or custom import builds—and then lift them as high as 20 inches for undercarriage work, brake service, suspension access, or tire changes. The combination of 3″ lowered height and 20″ maximum lift gives it real versatility for mixed fleets in a shop.
Mobility in the working area is handled by swivel casters that allow smooth positioning without fighting the jack. The release and lowering mechanism employs a twist control system that gives the user fine control over descent speed, letting you lower carefully rather than dropping the vehicle too fast. A universal-joint pressure release mechanism provides smooth operation, reducing jerky movements. Internally, it uses a roller cam dual–plunger pump and sealed hydraulics to extend system life and resist contamination from shop grime or moisture. To prevent misuse, the jack includes a safety overload system that helps guard against exceeding capacity and damaging components. The sides of the frame are flanged for extra rigidity and strength to resist twisting or flexing under load.
Key performance specs include a lifting capacity of 5,000 lb, a minimum pad height of 3″, and a maximum lift height of 20″. The front width is approximately 10.5″ while the rear width is about 14″, giving it a stable footprint under load. The shipping weight clocks in near 74 lb, which is a manageable heft for shop handling.
In use, the floor jack should be set on a flat, rigid floor surface rated to support both the load and the jack itself. The load must be centered on the saddle before lifting. As the vehicle rises, jack stands rated for the load should immediately be placed under proper lift points—never rely on the jack alone for support. To lower, twist the release control slowly to allow a controlled descent. Because the jack’s hydraulics may contain air from transit, the user should purge the system before first use. Routine maintenance includes keeping pivot points, casters, and saddles greased, checking the hydraulic fluid level, and inspecting welds, seals, and moving parts for wear or damage. Any jack exhibiting unusual behavior must be removed from service until evaluated.
For shops working on a mix of cars, light trucks, and performance builds, the RFJ-5000HD is a solid jack that balances the low clearance needs of exotic or lowered cars with the lifting range for taller vehicles. Its industrial construction, mobility, and safety features make it suitable as a core lifting tool in busy service bays.
