What is a rolling jack used for on a 4-post lift?

A rolling jack lifts an individual wheel or the full vehicle while it sits on a 4-post lift, giving you clearance to change tires, service brakes, or work on suspension components. It rolls freely along the runways so you can position it exactly where the vehicle needs support.

What capacity rolling jack do I need?

Capacity should match the heaviest vehicle you regularly service, not the average job. Vovlift offers 5,000 lb models for passenger cars, 6,000-10,000 lb units for light trucks and SUVs, and the AMGO RJ-20A at 20,000 lb for full-size trucks and heavier commercial vehicles.

Do Katool rolling jacks fit any 4-post lift?

No, Katool rolling jacks like the KT-RJ50, KT-RJ60, and KT-RJ70 are built to fit specific Katool 4-post lift models such as the KT-4H110, KT-4H150, KT-4H850, and KT-4H950. Confirm your exact lift model before ordering to ensure compatibility.

Is a pneumatic rolling jack better than a manual one?

Pneumatic rolling jacks use shop air to lift faster with less operator effort, making them a better fit for high-volume shops. Manual rolling jacks like the AMGO J5H and J6H cost less upfront and work well for lower-frequency use in smaller operations.

How to Choose a Rolling Jack for Your 4-Post Lift

What Is a Rolling Jack?

A rolling jack is a mobile hydraulic lifting unit that rides on the runways of a 4-post lift, letting you raise a wheel or the entire vehicle for tire changes, brake work, or suspension service without removing the car from the lift. It rolls into position, engages the frame or tire, and lifts independently of the main lift platform.

What Capacity Do You Need?

Match the rolling jack's rated capacity to the heaviest vehicle you service, not just your typical daily job. Vovlift carries 5,000 lb units for passenger cars and light trucks up to 20,000 lb models like the AMGO RJ-20A for full-size trucks, vans, and heavier commercial vehicles.

Manual, Pneumatic, or Automatic Pump?

Manual rolling jacks like the AMGO J5H and J6H cost less and suit lower-volume shops, while pneumatic (air/hydraulic) models such as the AMGO RJ-8A and Katool KT-RJ70 speed up repetitive lifts using shop air. The AMGO RJ-20A adds an automatic pump for the highest-capacity, highest-throughput jobs.

Does the Rolling Jack Need to Match Your Lift Brand?

Katool rolling jacks like the KT-RJ50, KT-RJ60, and KT-RJ70 are built to fit specific Katool 4-post lift models (KT-4H110, KT-4H150, KT-4H850, KT-4H950), so confirm your lift model before ordering. AMGO rolling jacks are sized by capacity and generally fit a wider range of 4-post lifts.
