Atlas® RJ8BKAH 8,000 lb Bridge Jack #ATEATPK-RJ8BKAH-FPD

Atlas RJ8BKAH — 8,000 lb Air/Hydraulic Bridge Jack

A four-post lift that can't lift the wheels off the runway is a parking deck, not a service bay. The Atlas RJ8BKAH — the manufacturer's current 8,000 lb air/hydraulic rolling bridge jack (RJ8000BK) — is the fix: it rolls on your lift's runway tracks, spans 33 to 53 inches between them, and puts the axle in the air at 27 inches with adapters.

It's the jack the manufacturer's own 14K alignment lift (414A) recommends, with two solid locking positions, telescoping arms over the runways, peg-style truck adapters included, and a scissor mechanism for level lifting — freight prepaid.

Who the Atlas RJ8BKAH Bridge Jack Is Built For

• Owners of Atlas 4-post lifts adding wheel service — the RJ8BKAH turns a drive-on storage or service lift into a brake and wheel bay without buying a second lift.
• Shops servicing HD trucks — 8,000 lbs of bridge capacity holds 3/4-ton and 1-ton axles at working height on two solid locking positions.
• Bays with 33"–53" between the runways — the roller system spans that range; measure the gap before ordering and the fit is known.
• Shops already running 70–115 PSI shop air — the air/hydraulic operation needs it (external air supply required, not included).
• Buyers of the 414A or other Atlas HD 4-posts — this is the jack the manufacturer's own pages recommend for those runway tracks.

What the Atlas RJ8BKAH Bridge Jack Is NOT Built For

This is not for two-post lifts (bridge jacks ride 4-post runway tracks), not for runways wider than 53" or narrower than 33" apart, and not for shops without compressed air — the jack's hydraulics are air-actuated and the air supply is not included.

Compatibility note: measure the distance between your runways (fits 33"–53"), confirm the 8,000 lb capacity against the axles you service, and verify 70–115 PSI shop air before purchase. The manufacturer's current model designation for this jack is RJ8000BK. Questions on fit? Call (817) 865-3707 before ordering — we confirm compatibility, not guesses.

What Makes the Atlas RJ8BKAH Bridge Jack Different

8,000 lbs of bridge capacity

The heavy end of the Atlas bridge-jack line — enough rating for the 3/4 and 1-ton axles that make smaller jacks a math problem.

• 8,000 lb capacity
• 27" max lift with adapters
• Two solid locking positions

Built for 4-post runway tracks

Expandable rail supports with a roller system roll the jack along the runways; telescoping arms reach over the runway edges to the axle.

• Fits 33"–53" between runways
• Expandable rail supports + rollers
• Telescoping arms

Air/hydraulic operation

70–115 PSI shop air drives the hydraulics — smooth lift, positive lock, and no hand pumping. Exceeding 115 PSI can damage the jack.

Best For

• Atlas 4-post owners adding wheel service
• HD truck axles to 8,000 lbs
• Bays with shop air
• 414A / HD 4-post tracks

Not Ideal For

• 2-post lifts
• Runway gaps outside 33"–53"
• Shops without compressed air

Atlas RJ8BKAH vs Atlas RJ45A — two bridge jacks, two duty classes

Both ride Atlas 4-post tracks on shop air — the RJ8BKAH is the heavy-duty play, the RJ45A the compact one.
