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.

The Katool KT-RJ70 is a 7,000 lb air/hydraulic rolling jack designed to work with the KT-4H110, KT-4H850, and KT-4H950 four-post lifts, adding a mobile lift point under vehicles already raised on the rack. At 7,000 lb, it covers the full range of passenger cars, light trucks, and SUVs those lifts handle — including heavier configurations where a 5,000 lb jack would be at or near its limit. Note: an external air supply is required for operation.

The low-profile, compact frame slides between the lift runways and positions under low-clearance vehicles without modification or workarounds. Once in place, the air/hydraulic system raises and lowers smoothly and with control — important when you're unloading a suspension corner for alignment work, dropping a brake assembly, or supporting a differential during an axle pull. Smooth-rolling casters let one person move and position the jack along the runways quickly, keeping bay time down between jobs. A powder-coated finish holds up against the oil, grime, and daily contact that comes with shop floor use.

The KT-RJ70 is the right fit for professional shops and serious home mechanics running a compatible Katool four-post lift who need a higher-capacity rolling jack for heavier trucks and SUVs, or who simply want more headroom before hitting the weight limit. It ships backed by a 1-year parts warranty.

Features

• 7,000 lb lifting capacity suitable for a wide range of passenger vehicles, light trucks, and SUVs
• Compatible with Katool four-post lifts KT-4H110, KT-4H950, and KT-4H850 for a fully integrated shop setup
• Air/hydraulic operation uses an external air supply for smooth, controlled lifting and lowering
• Compact, low-profile design fits easily between runways and under low-clearance vehicles, maximizing workspace accessibility
• Smooth-rolling action allows quick, precise positioning along lift runways
• Rugged powder-coat finish resists rust, scratches, and everyday shop wear
• Backed by a 1-year parts warranty for added peace of mind

The Katool Caster Kit is a set of 4 casters designed exclusively for the KT-4H110 four-post lift — it is not compatible with other models. Each caster is rated at 0.5 tons, giving the full set a combined capacity of 2.0 tons, which allows the unloaded lift to be repositioned within your garage or shop without disassembly.

A straightforward add-on for KT-4H110 owners who need the flexibility to move their lift between bays, clear floor space for other work, or adjust the lift's position as their shop layout changes. If mobility is part of how you use your garage, this kit is the purpose-built solution for that lift.
