APlusLift BJK-45 4,500 lb Air Sliding Jack (Crate) #BJK-45

APlusLift BJK-45 — 4,500 lb Air Sliding Jack

A four-post lift without a bridge jack is a parking deck — the wheels never leave the runway, and brake work happens somewhere else. The APlusLift BJK-45 is the bridge jack that finishes the lift: 4,500 pounds of air-operated capacity, sliding on an adjustable frame that fits almost all service and storage lifts, lifting axles 4 3/4 to 12 1/8 inches above the runway.

The width adjustability is the real spec: overall length extends from 35 5/8 to 46 7/8 inches, with arm pads spanning 32 11/16 to 59 7/16 inches — one jack that fits the fleet of lifts a shop actually owns, instead of a jack married to one runway width.

Who the APlusLift BJK-45 Is Built For

• Four-post owners adding wheel service — the BJK-45 turns a storage or service lift into a brake-and-wheel bay on the same footprint.
• Multi-lift shops — the adjustable width (35 5/8"–46 7/8" overall, 32 11/16"–59 7/16" between pads) is designed to fit almost all service and storage lifts, so one jack model covers the shop's fleet.
• Shops with compressed air — air operation means smooth, controlled lifts under a 4,500 lb axle with no hand-pump workout.
• Shops that want adapters in the box — two drop-in pads, two 1/4" truck adapters, and two 4 15/16" truck adapters ship with the jack, covering light-truck lifting points out of the crate.
• Buyers comparing bridge jacks — 4,500 lbs, adjustable width, 12-month warranty: the honest comparison class for the Atlas RJ45A.

What the APlusLift BJK-45 Is NOT Built For

This is not for two-post lifts (bridge jacks ride 4-post runway tracks), and it's not a heavy-axle tool — 4,500 lbs is the light-truck class, with the bigger jacks covering 3/4-ton work. Like all air-operated jacks it needs shop air at the point of use.

Compatibility note: measure your runway width and the distance between your lift's runway tracks (the jack adjusts from 35 5/8" to 46 7/8" overall), confirm 4,500 lb capacity against your axles, and verify shop air before purchase.

What Makes the APlusLift BJK-45 Different

Adjustable width — the fitting spec

The frame adjusts from 35 5/8" to 46 7/8" overall with arm pads spanning 32 11/16" to 59 7/16" — the manufacturer's stated goal is fitting almost all service and storage lifts.

• Adjustable overall length
• Wide arm-pad span
• Fits almost all 4-post lifts

Air operated, 4,500 lbs

Shop air lifts the axle smoothly from 4 3/4" to 12 1/8" above the runway — brake and wheel work at runway height without hand pumping.

Adapters in the box

Two drop-in pads, two 1/4" and two 4 15/16" truck adapters — the light-truck lifting points are covered on delivery day.

Best For

• 4-post owners adding wheel service
• Multi-lift shops (adjustable fit)
• Light-truck axle work
• Shops with compressed air

Not Ideal For

• 2-post lifts
• Axles over 4,500 lbs (see RJ8BKAH class)
• Shops without compressed air
