The Auto Lift RJ-45 Rolling Jack is a professional-grade scissor-style rolling bridge jack engineered specifically for use with four-post automotive lifts. With a robust 4,500 lb. capacity, this jack transforms your four-post lift into a wheels-free lifting system, enabling full suspension work, brake service, and undercarriage access on passenger cars and many heavy-duty pickup trucks. Designed to mount directly into your lift's jack rails, the RJ-45 features manual hand pump operation that requires no air compressor, making it ideal for both busy professional shops and home garages where a clean, uncluttered workspace is essential.
The scissor-style design ensures level, stable lifting every time, while spring-loaded rollers maintain positive contact with the jack rails for smooth, controlled operation. The jack's low-profile design with a minimum lifting height of just 3.75 inches allows you to work on lowered vehicles and sports cars, while the maximum lift height of 11 inches (expandable to 16 inches with included extensions) provides ample clearance for most service tasks. The adjustable width base (ranging from 33.9" to 49.6") and extendable arms (from 34.25" to 57.48") ensure compatibility with most four-post lift configurations.
The RJ-45 features a low-profile design that starts at just 3.75 inches above the runway, making it perfect for lowered vehicles and sports cars. The spring-loaded rollers automatically maintain positive contact with the jack rails throughout the entire lifting range, ensuring smooth, stable operation without manual adjustment. A durable powder coat finish protects against corrosion and shop chemicals, while the precision-engineered scissor mechanism delivers level, controlled lifting for safe, professional results.
Each RJ-45 Rolling Jack includes both 1-1/2" extension adapters (for 5.25" - 12.50" total lift range) and 5" extension adapters (for 8.75" - 16.00" total lift range), giving you maximum versatility for different vehicle heights and service requirements. The jack's smooth rolling operation on precision wheels makes positioning effortless, while the three safety lock positions ensure secure support at multiple working heights.
Despite its substantial 4,500 lb. lifting capacity, the RJ-45 maintains a relatively compact footprint at 34.25" L x 22.05" W x 7.48" H in its lowest position. The heavy-duty construction weighs 363 lbs., providing the stability needed for safe operation while remaining manageable for shop placement. The jack's adjustable base width expands from 33.9 inches to 49.6 inches, and the extendable lifting arms reach from 34.25 inches to 57.48 inches, ensuring compatibility with a wide range of four-post lift models and vehicle wheelbases.

Built for professional shop environments and serious DIY enthusiasts, the Auto Lift RJ-45 combines rugged construction with user-friendly operation. The hand pump mechanism provides precise control over lifting speed and height, while eliminating the noise, maintenance, and air line requirements of pneumatic systems. Whether you're performing routine brake service, suspension repairs, or detailed undercarriage work, the RJ-45 Rolling Jack expands your four-post lift's capabilities to rival that of a traditional two-post lift—with the added convenience of drive-on loading and the stability of four-point support.
Note: The RJ-45 is specifically designed to fit the Auto Lift Car-Park-9 model. Please verify compatibility with your specific four-post lift model before ordering. Contact our team if you need assistance determining the right rolling jack for your lift.
