The Challenger 44AK40 air line kit is the direct replacement for the Challenger lift it came off of. This is the genuine Challenger part — same fit and same working specification as the one already on your lift. Ordering the Challenger air line kit from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.

Specifications

• Part number: 44AK40
• Brand: Challenger
• Type: Genuine OEM air line kit

On lifts that use air — for lock release or pneumatic engagement — the air supply is part of the safety system, not an accessory. A compressor or regulator that can't hold steady pressure means the locks don't actuate the way they're supposed to. The air side is simple, but it has one job that matters: deliver clean, regulated pressure on demand so the lock mechanism does exactly what the operator asks.

Replacing your air line kit

Applying new decals is simple but not trivial: the surface has to be clean and dry, and the capacity and safety labels have to go in their correct, visible locations so an operator can read them at a glance. Take your time positioning them. The full procedure covers placement and prep. Not sure on the procedure? Find your lift in our parts lookup or call and we will walk you through it.

Find the right part for your lift

Landed here but not 100% sure it is your part? Grab the model and serial from the data plate and open our Challenger parts lookup for the visual breakdown — the manufacturer-style drawing with every item numbered so you can match yours exactly. Plate missing? our guide to finding your model number helps, and we identify lifts from photos every week if you would rather ask.

Signs it's time to replace it

For airlines, run the length looking for cracks, kinks, chafe points, and oil-swollen or brittle sections. Check every push-connect and threaded fitting for leaks — a quick spray of soapy water shows bubbles at a leak. Pull the lock release and confirm air actuates the pawls promptly; a soft, slow, or uneven release points to a leaking line, a bad fitting, or low supply pressure.

Parts commonly replaced at the same time

While you are ordering, let us check what commonly goes with it on your lift. Bundling the related parts into one shipment saves freight and time, and we can see the full breakdown for your model to make sure nothing obvious is missed. Just give us the model and serial.

Safety notes

Fit the right part and follow the manual — that holds even for the minor components. Required safety and instruction decals must stay legible for ALI compliance, and any accessory in the load path has to be rated for the job. When in doubt about what your model takes, ask before you order.

Before you order

Order by model and serial so we can match the correct version, and let us know the application. For decals and accessories especially, using the item specified for your lift keeps it compliant and safe. We will confirm the fit before it leaves the shelf.

Not sure this fits? Here's how to check

Pull the number off your lift's model plate first — model and serial both. Manufacturers run mid-cycle revisions that keep the model name but change hardware, so two lifts with the same name on the column can take different parts. The serial is what removes the guesswork.

Second check: compare the old part against this listing before you order. Length, mounting pattern, and thread sizes tell most of the story. If anything doesn't line up, or if the old part is too worn or broken to measure, call us with photos — we work on these lifts every week and can usually confirm fit from a picture and the lift's serial faster than you can dig through a parts diagram.
