The Challenger 44AK18 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: 44AK18
• Brand: Challenger
• Type: Genuine OEM air line kit

An airline is only interesting because of what it controls — usually the lock releases and, on some lifts, pneumatic lock engagement. Shop air runs through it to pull the pawls so the lift lowers evenly. When the line cracks, kinks, or a fitting leaks, the lift may not release all its locks together, which means it comes down cocked. A small pneumatic problem shows up as a lock-timing problem.

Replacing your air line kit

Replacing an airline is quick work — cut the new line to length, seat it fully in its push-connect or threaded fittings, and route it clear of pinch and chafe points. Then pull the lock release and confirm the air actuates every pawl cleanly and together. Since the air side controls the locks, the step-by-step guide is worth a look before you rely on 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

Give the lift a general walk-around for the small stuff that gets missed. Look for missing pins, clips, and retainers; loose covers and guards; chafed wiring or tubing; and anything rattling that shouldn't. These little items don't stop the lift, but a missing retainer or an unguarded pinch point is how a small oversight turns into an injury or a bigger failure down the line.

Parts commonly replaced at the same time

Small parts are a good moment to catch up on the rest — decals that are fading, hardware that is due, accessories that pair with what you are buying. We keep the parts breakdown for your model, so one call can round out the order and save you a second wait.

Safety notes

Small parts still matter on a lift. Whether it is a decal an inspector checks for or an accessory that has to be rated for the load, use the correct item for your model and install it the way the manual specifies. Cutting a corner on a small part is still cutting a corner on a lift.

Before you order

A quick prep before ordering: model, serial, and what the part is for. Even minor components come in model-specific versions, and the right one depends on details on your data plate. Call and we will confirm before anything ships.

Check your lift's serial before ordering

The most common reason a lift part comes back is not a defect — it is a revision mismatch. Manufacturers change sub-parts between production runs while keeping the same lift model name, so "it fits my lift model" is not always enough. The model plate carries the serial number that pins your lift to a specific run, and that is the number that settles which version of this part belongs on your lift.

Can't find the plate? Measure the old part — overall length, bolt-hole spacing, thread size on anything threaded — and photograph it from a couple of angles. Send that with your lift's brand and rough age and we will match it against the parts breakdowns we service from every week.
