Overview
The Challenger RJ6 Rolling Jack is a professional-grade air/hydraulic lifting accessory engineered to maximize the functionality of 4-post vehicle lifts. With a 6,000 lb capacity, this rolling jack transforms your lift into a complete wheel-service station, enabling efficient tire changes, brake service, and suspension work. The jack rolls smoothly along accessory rails, features adjustable width arms to reach manufacturer-recommended pick-up points, and incorporates two-hand safety operation for controlled use. Its low-profile design (lowered height of just 3 3/8 inches) keeps the workspace unobstructed when not in use, while the air-over-hydraulic system delivers smooth, powerful lifting with minimal effort.
