A heavy truck under axle jack with air assist and a long handle for shop floors. Its frame stands too tall for low cars, so it serves heavy trucks and vans, not passenger cars.

Overview
Reaching under a long overhang from the handle end, the OTC under axle jack is an air-assisted hydraulic jack for heavy trucks. One pull of the handle starts the ram, a spring return retracts it, and saddle attachments set the starting height.
Shop air does the work, and the long T-handle lets you place the jack without crawling under the truck. The jack is big and heavy, and its spec table lists heights that conflict with the description, so plan around the saddle chart.
Who it's for
Fleet and heavy truck shops with compressed air get an axle jack that is positioned from the handle end. Car owners and garages without an air supply should look at a standard floor jack.
Pros and cons
- Air assist operation from shop air
- Long T-handle reaches under overhangs
- Self-retracting spring return on the ram
- Three saddle attachments set lift height
- Needs shop air at the rated pressure
- Spec table heights conflict with the description
- Too tall to fit under passenger cars
Performance notes
The hydraulic ram does the lifting with air assist doing the pumping, so lift speed depends on the air line holding pressure. Saddle choice sets the starting height, and the large rubber-tired steel wheels help the jack roll across most shop floors.

Frequently asked questions
Which OTC UA22 saddle attachment gives which lift height?

Does the OTC UA22 need an air compressor?
It uses air-assist operation rated at 90 to 145 PSI, so plan on a shop air supply.
Can the OTC UA22 lift a passenger car?
The listing names trucks, vans and Class 7/8 vehicles, with an 8.27 inch frame height. It is built for heavy truck axles, not low passenger cars.
Why does the OTC UA22 spec table show a 3 inch maximum height?
The spec table lists 3 inches maximum and 4.5 inches minimum, which conflicts with the description's 8.27 to 20-2/3 inch lifting range. Use the description and saddle chart when planning.
