Getting under the car is the whole problem — this one starts at 3-5/8″
A jack that cannot reach the lift point is no use at all, whatever its rating says. The Ranger RFJ-6HD is built around that single sentence. Its pad starts at 3-5/8″ (90 mm) off the floor — the description supplied with the product rounds the same figure to 3.6″ — which is low enough to slide under a lowered import, a sports car on a modest drop or a modified build with a front splitter, without ramps, boards or a friend lifting the nose. From there it lifts to 21″ (533 mm), which is a full service height rather than a token one.
Low entry and high reach do not usually come together, because a jack low enough to get under a car is normally short of travel. Carrying both is what the "Low Rider" name is actually describing, and it is why this model suits a shop that sees a mixture of vehicles rather than one type. Capacity is 6,000 lbs (2,722 kg) — 3 tons.
Will It Fit?
-
Entry height. 3-5/8″ (90 mm) at the pad, fully lowered. Measure the clearance under the sill of your lowest car at the actual lift point, with the car loaded as you will use it. This figure is the reason to buy the jack, so it is the figure to check first.
-
Lift height. 21″ (533 mm) at the top of the pad. Check it against the working height of your jack stands.
-
Reach. A 27″ (686 mm) chassis, which puts the saddle under the jack points on most cars and light trucks without an angled approach.
-
Footprint. 11″ (279 mm) across the front, opening to 14″ (356 mm) at the rear. The narrow nose is what threads into a gap; the wide rear is what keeps the jack stable once the load is on it.
-
Floor. Flat, hard and level. Swivel casters on a cracked slab or a sloped driveway make a rolling jack unpredictable, whatever it is rated at.
Confirming the clearance and the lift-point positions on your own vehicles is the buyer's responsibility, and it is ten minutes with a tape measure against a return. Send us the cars and we will check the numbers with you.
Two different weights are on file, and we are showing you both
The data we hold for this jack gives its weight twice and the two do not agree. The specification table states a shipping weight of 94 lbs (43 kg). The description supplied with the product says the jack weighs about 108 lbs. One of those is wrong, or they are measuring different things — a crated weight against a bare unit weight would explain a gap of that size, but nothing in the data says so, and we are not going to guess on your behalf.
Both figures are printed here rather than one quietly deleted. If the weight matters to your purchase — because you need to lift it into a truck, carry it up a step, or because a service vehicle has a payload limit — ask us and we will confirm the bare weight against the current factory sheet before you order.
The quick-pump, and why the first strokes are the ones that count
Most of a jack's pumping is wasted effort. The saddle has to travel from the floor to the underside of the car before it touches anything, and on a jack this low that empty distance is longer than usual. The RFJ-6HD uses a quick-pump arrangement to cover it in a handful of strokes, after which a dual-plunger pump takes over for the loaded lift.
On a single job that is a convenience. Across a tyre-change day, an inspection lane or any repetitive wheel-off work, it is the difference between a tool you reach for and one you avoid. It is also easier on the operator's shoulder, which is a real consideration for anyone doing this forty times a week.
Control on the way down, and grip at the saddle
The release runs through a universal-joint linkage, so the valve answers to partial turns of the handle rather than opening all at once. That is what lets a lifted corner be walked down onto stands gradually enough to see the stand taking the load squarely — the moment where a coarse release valve drops the car the last inch and shifts everything.
The saddle itself is hardened steel with a rubberised contact pad. The rubber is not a comfort feature: it grips a painted or coated lift point instead of skating across it, and it keeps the steel off the underside of the car, which matters on anything you care about the appearance of.
The body is heavy-gauge steel with flanged side plates, which stops a long, low chassis flexing under a full load; the hydraulics are double sealed against the grit and oil mist that actually kill jacks in workshops, and an overload valve bleeds pressure rather than letting the jack be pumped past its rating.
Perfect For
-
Mixed-fleet workshops — the same jack goes under a lowered car in the morning and lifts a light truck in the afternoon.
-
Performance, tuning and restoration shops, where the entry height is the constraint that rules other jacks out entirely.
-
Tyre and wheel work, where the quick-pump earns its keep over a day of repetition.
-
Home garages with a low car in them, and no wish to own two jacks to cover one driveway.
Using it safely
Roll the jack under a manufacturer-designated lift point, centre the saddle before you start pumping, and raise to the height you need. Then place rated jack stands and lower the vehicle onto them with the twist release before anything goes underneath. A hydraulic jack lifts; stands hold. Keep the pivots lubricated, check the fluid level, and if lift becomes sluggish, bleed the system — trapped air is the usual explanation and it is a two-minute fix rather than a fault.
What's in the Box
The jack and its handle. Nothing further is itemised in the copy on file, so treat rated jack stands, adapter pads and any service kit as separate purchases. We would rather state that than list contents we cannot confirm — ask us if you need the packing list checked before you order.

Certification, stated honestly
The product data we hold for the RFJ-6HD makes no third-party safety-listing claim of any kind, and we will not imply one it has not made. If your insurer, a fleet contract or a local inspection scheme requires lifting equipment to carry a specific independent listing, treat that as an open question and verify it against the manufacturer's documentation before you buy — ask us and we will put the request to Ranger in writing. Whatever the paperwork says, the rule that prevents injuries is unchanged: the jack raises the vehicle, rated stands hold it, and nobody goes underneath until the stands are loaded.
Shipping and delivery
Shipping is quoted live at checkout against your own address, so the number you see is the real one. Heavier orders travel by freight carrier, and freight delivery is kerbside — you need to be able to take the item off the truck, or you can collect from the carrier's local terminal instead. A residential delivery address adds a residential fee, charged once per brand on an order rather than for each item. Inspect the shipment before you sign and write any damage onto the delivery paperwork at the time; once a clean receipt is signed a claim becomes very hard to run. We ship within the contiguous United States.
Warranty
Ranger issues one warranty document covering its product line and we hold a copy for this model. No term is printed on this page because the data we hold does not state one, and a warranty length invented to fill the gap would be worse than the gap itself — ask us and we will send you the current document before you order. If the jack drifts down under load, loses lift or leaks, take it out of service and contact us before you open the cylinder, the pump or the release assembly. A dismantled hydraulic unit is normally outside any claim, and a fault we can see intact is one we can get resolved.
