The Katool KT-RJ50 is a 5,000 lb air/hydraulic rolling jack engineered specifically for use with the KT-4H110, KT-4H850, and KT-4H950 four-post lifts — it slides under a vehicle already raised on the lift, giving you a stable second lift point for suspension, brake, and drivetrain work without pulling the car off the rack. Note: an external air supply is required for operation.

The jack runs on a scissor mechanism that raises the load level rather than tipping it, which matters when you're working under a suspended drivetrain or need to support a subframe evenly. Its low-profile design fits under vehicles with minimal clearance once they're on the four-post, and the smooth-rolling casters let one person reposition it under the lift without fighting the floor. A powder-coated finish protects the steel from the oil, grime, and moisture that accumulate on any shop floor.

The KT-RJ50 is the right add-on for professional shops and serious home mechanics running a Katool four-post lift who want to do more than park or store vehicles on it. If you're turning rotors, pulling axles, or dropping a transmission, having a rolling jack already matched to your lift's frame width and load rating removes the guesswork. It ships freight prepaid and is backed by a 1-year parts warranty.
