The Atlas® RJ-45 Rolling Jack is an economical rolling hydraulic jack designed to raise the front or rear portion of a vehicle allowing the operator of a four post above ground lift to perform wheel and brake service. Most commercial shops buy two of the hydraulic rolling jacks, so that the entire vehicle can be supported in the air at the same time.

The Atlas® RJ-45 Rolling Jack is the perfect accessory for the Atlas® Garage Pro 9000. The complete Atlas® Garage Pro 9000 four post lift comes with a jack tray. The jack tray has certain limitations that are eliminated by using the Atlas® RJ-45 Rolling Jack. The jack tray (with a small floor jack or jack stands) will support ONLY THOSE LIFTING POINTS of the raised vehicle that are between the runways of the Atlas® Garage Pro 9000 four post lift. The Atlas® RJ-45 Rolling Jack has telescoping arms that can be extended over the runways of the four post lift. The lift pads at the end of these arms can be positioned under the LIFTING POINTS (that are located over the runways of the four post lift) of the vehicle allowing the operator to access many more LIFTING POINTS than just using the jack tray.

The Atlas® RJ-45 Rolling Jack is equipped with expandable supports which adjust to fit many different brands of four post above ground lifts. These supports have a unique roller system that allows the rolling hydraulic jack to glide easily under the entire length of the vehicle. The large nylon rollers and heavy steel wheels allow the rolling jack to be positioned under the correct lifting points in a matter of seconds.

The Atlas® RJ-45 Rolling Jack comes standard with a set of peg style truck adapters which increase the lifting height of the lift pads. These truck adapters will allow the Atlas® RJ-45 Rolling Jack rolling hydraulic jack to raise pick-up trucks that will sit higher off the runways than the average passenger car. The Atlas® RJ-45 Rolling Jack can be operated with the manual hand pump that is also found on the Atlas® RJ-35 Rolling Jack or it can be equipped with a commercial air/hydraulic pump. The air/hydraulic pump would require a supply of compressed air (air compressor) to work properly. The Atlas® RJ-45 Rolling Jack rolling hydraulic jack features two solid locking positions that are used when the vehicle is to be suspended above the runways. When the locking positions of the Atlas® RJ-45 Rolling Jack are engaged, the hydraulic pressure from the lifting cylinder of the Atlas® RJ-45 Rolling Jack is eliminated. (These locks act much like a pair of jack stands after you lift a vehicle off the ground with a service jack).

Great jack, Great quality, Best price


This is a well built, well designed and strong heavy duty jack, already pre-assembled and ready to rock. I've had sliding jacks on other lifts before, but this one is really, really nice. Rolls like a Cadillac! Greg Smith has always been my "go-to" source when I want a great product, a the best price and shipped the least expensive way possible. And they have most everything in stock. And if you need anything, they are there to help right away.

All jacked up


I purchased the RJ-45 Rolling Hydraulic Center Jack with my HX PRO9000 lift and it is the perfect accessory. It rolls easily, has adapters for different height situations and jack's effortlessly. The purchase of the XH-PRO9000 lift and this jack make my new garage complete. I am very pleased with the quality of both and the price.
