Product Description Ranger RFJ-4000AL: a 4,000 lbs racing jack Ranger rates in pump strokes, not just pounds Most floor jacks are sold on capacity alone. Ranger publishes something more useful for the RFJ-4000AL: how many strokes of the handle it takes to do the job. Three quick pumps bring a car off the ground, and four raise it to full height. That is the number that decides whether a corner-of-the-car wheel change takes twenty seconds or two minutes, and it is why this jack belongs in pit lanes and fast-moving service bays rather than at the back of a tool chest. The other half of the story is what it is made of. The body is aircraft-grade billet aluminum, so the whole jack weighs 44 lbs while still carrying a rated 4,000 lbs — 2 tons — of vehicle. A steel jack of the same capacity is something you drag; this one you carry to the car in one hand and set down exactly where you want it. Will It Fit Under Your Car? A jack that will not slide under the pinch weld is a jack you cannot use, so measure before you order rather than after. Lowest point of entry: the saddle sits at 3.5" (89 mm) when fully collapsed. Compare that against the ground clearance at your vehicle's jacking point, not against the clearance in the middle of the floor pan. How high it goes: 17.75" (451 mm) at the top of the pad, enough to get a wheel clear for a change, get stands under the sills, or open up room for brake and suspension work. Room to work: the chassis is 24" (610 mm) long and 11.75" (298 mm) wide, so it needs a clean strip of floor beside the car roughly the length of a door opening. Floor: the surface must be flat, hard and level. The casters and the front roller have to travel as the arm rises — a jack that cannot roll toward the car binds and pushes the vehicle sideways instead of lifting it. Ruling out gravel, soft asphalt on a hot day and sloped driveways is the customer's responsibility; we cannot assess your floor from here. Why a pump count is a real specification The speed comes from a dual-plunger pump assembly running roller-cam plungers. Two plungers move more oil per stroke than one, and the roller cams cut the friction that makes a cheap jack feel like it is fighting you near the top of the stroke. The practical result is the stroke count above: the saddle closes on the vehicle in a few short, light pulls rather than a dozen long ones. In a shop lifting a car twenty times a day that adds up to hours over a year. On a race weekend it is measured in positions. The handle is oversized knurled aluminum, which matters more than it sounds. A smooth or narrow handle is the first thing to slip when your hands are oily, and a handle slipping under load is the moment a lift goes wrong. Knurling gives a grip that still works with gloves on. What the aluminum buys, beyond the weight Lightness is the obvious benefit, and it is the one that makes this a genuine trackside tool — it goes into the back of a car, into a trailer, or up onto a shelf without a second pair of hands. The less obvious benefit is corrosion. An aluminum body does not rust from road salt, brake dust and the damp concrete a jack spends its life on, which is what usually kills a steel jack long before its hydraulics wear out. The one component that has to be steel is treated accordingly: the ram is alloy plated, because that is the surface a hydraulic seal wipes across thousands of times, and a pitted ram is what becomes a leaking jack. The hydraulics themselves are double sealed against the grit and moisture in shop air, which is also why routine care here is mostly inspection rather than servicing. Underneath, a low-profile single-piece front roller carries the load as the chassis moves in. One piece spreads that load over a wider contact patch and leaves one fewer joint to wear or seize. Control on the way down, a limit on the way up Lowering is where jacks hurt people. The RFJ-4000AL uses a universal-joint release, which gives a progressive feel at the handle instead of an on-off valve — you can meter the descent, pause it, and set a car down onto stands gently rather than dropping the last part of the travel. A built-in safety overload valve sets the other boundary: try to lift past the rated capacity and it bleeds off rather than letting an operator load the structure beyond its design. Neither feature replaces jack stands. A hydraulic jack is a lifting device, not a support device, and nobody should ever be under a vehicle held up by one. Raise the car, place rated stands at the manufacturer's support points, and lower the vehicle onto them before anything goes underneath. Perfect For Race and track-day teams who need the car up in seconds and need to carry the jack between paddock and grid. Professional service bays doing high-volume tire, brake and suspension work, where the jack is picked up and repositioned dozens of times a shift. Home garages with a performance car — low entry, no rust, and light enough to stand on a shelf instead of eating floor space. Mobile technicians who need real capacity from a jack that loads into a van without a ramp. What's in the Box The jack ships as a complete assembled unit with its knurled aluminum handle. Jack stands, wheel chocks and pad adapters are not included, and nothing in Ranger's own feature list for this model implies they are — if you want stands rated to match, ask and we will quote them alongside.

What the product data we hold does not contain is any independent third-party safety listing for it — an outside laboratory's mark is a different document from a manufacturer's own specification sheet, and we will not imply one our data does not show. If your insurer, your employer's safety programme or a circuit's scrutineering rules require lifting equipment to carry a specific independent listing or a written standards-compliance statement, tell us before you order and we will ask Ranger for it in writing rather than guess on your behalf. Shipping and delivery We ship to the lower 48 states, free of charge. Residential delivery carries a residential fee, shown at checkout before you pay. Pickup is also available at the Ranger locations listed further down this page if collecting suits you better. Inspect the shipment before you sign. If the carton is crushed, torn or oil-stained, write the damage onto the delivery paperwork at the moment of delivery — a clean signature is treated by carriers as an undamaged delivery, and it becomes far harder to resolve afterwards. Photograph anything that looks wrong and contact us the same day. Warranty and service This jack is covered by Ranger's published warranty document, linked on this page. We have deliberately not restated its terms here: the document is the authority, and we would rather you read the current version than a summary that drifts out of date. One thing worth knowing in advance — do not disassemble the hydraulic unit before making a claim. Opening a sealed hydraulic assembly generally ends coverage on it, and a jack losing height or seeping oil is a warranty conversation, not a bench repair to attempt. Call, text or chat with us and we will start it.
