The Atlas RJ8A rolling bridge jack delivers 8,000 lbs. of lifting capacity for four-post and scissor lifts, allowing you to raise a vehicle’s wheels off the runways for tire, brake, suspension, and driveline service. Its adjustable rail supports accommodate runway spacing from 36" to 56-1/2", making it compatible with a wide range of lift styles and brands. Before ordering, confirm that your lift’s runway spacing falls within this range. Operation requires an external shop air supply at 70–115 PSI, which is not included.
The RJ8A uses an air-over-hydraulic system and telescoping arms that extend across the runways. Its roller system lets you move the jack along the lift to position it beneath the area being serviced, while the scissor mechanism keeps the lifting pads level as the vehicle rises. Multiple mechanical safety-lock positions support the load once engaged, allowing hydraulic pressure to be released during service. The included four-piece truck adapter set—two 2.5" adapters and two 5" adapters—adds height for reaching lifting points on pickups and larger trucks.
This bridge jack is a practical addition for home garages, professional repair shops, and service facilities that need to perform wheel-free maintenance using an existing four-post or scissor lift. Its adjustable supports offer flexibility across compatible lift configurations, while the compact, low-profile frame makes positioning and storage easier. A powder-coated finish helps protect the frame in a working shop environment.
Features

FAQ
What types of lifts does the RJ8A fit?
The RJ8A is designed to bridge the runways of compatible four-post and scissor lifts. Its adjustable rail supports accommodate runway spacing from 36″ to 56 1/2″, making it compatible with a range of lift configurations and brands.
Before ordering, confirm that your lift's runway spacing falls within this range and that the jack's mounting configuration is compatible with your equipment.
What air pressure does the RJ8A require?
The RJ8A operates on shop air supplied at 70–115 PSI. An external air compressor or shop air line is required and is not included. Do not exceed 115 PSI, as excessive pressure can damage the jack.
Why is the truck adapter set useful?
Pickups, SUVs, and larger trucks often have higher ground clearance than passenger cars. The included four-piece peg-style adapter set adds lifting height to help position the pads at the appropriate vehicle lifting points without relying on the jack's full lifting stroke.
The set includes:
-
Two 2 1/2″ adapters
-
Two 5″ adapters
Always follow the vehicle manufacturer's recommended lifting points and the jack's operating instructions.
How do the safety locks work?
The RJ8A features multiple mechanical safety lock positions. Once a lock is engaged, hydraulic pressure is relieved so the mechanical locks support the load, similar to the principle of using jack stands. Multiple positions allow you to secure the jack at a suitable height for the job.
Always engage the safety locks according to the manufacturer's instructions before working beneath a raised vehicle.
