The Challenger 44840-3W hydraulic fluid 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 hydraulic fluid 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: 44840-3W
- Brand: Challenger
- Type: Genuine OEM hydraulic fluid
The hydraulic side of a lift is a closed loop: the power unit's motor drives a pump that pushes fluid from the reservoir, through a hose and fittings, into a cylinder that does the lifting, while a lowering valve meters it back to tank on the way down. Every part in that loop either moves fluid, holds pressure, or seals it in. When one link weeps or won't hold, the whole lift feels it.
Dirty or wrong fluid quietly wrecks hydraulic parts. Milky oil means water got in and the pump is cavitating; dark, gritty oil means the system is grinding itself and packing the filter with metal. Mixing ISO-32 and ATF, or topping off with whatever's on the shelf, changes the viscosity the pump was built for. Half the "bad cylinder" calls in a shop start as fluid that should have been changed years ago.

Replacing your hydraulic fluid
Most hydraulic repairs share the same discipline: relieve pressure, keep the system clean, replace the part, then bleed the air and verify the lift holds under load. Contaminated fluid or trapped air will undo an otherwise good job. Because these parts keep a vehicle safely in the air, the full procedure is worth following start to finish. 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
Not certain this is the exact part your lift needs? Start with your lift's model and serial off the data plate, then open our Challenger parts lookup to see the visual parts breakdown for your model — the exploded drawing with every part numbered and priced. If your plate is missing or unreadable, our guide to finding your model number walks through where to find it, or send us a photo and we will identify the lift for you.
Signs of a hydraulic problem
A spongy or bouncy lift under load is air in the system or a failing seal letting pressure bleed past the piston. Bleed the cylinders first; if it's still soft, the piston seal isn't holding. Watch the rise, too — a cylinder that stalls partway or shudders is either low on fluid, sucking air, or scored inside so the seal skips.
Parts commonly replaced at the same time
A hydraulic repair is the right moment to handle the parts that fail alongside this one — seals, o-rings, the hose that feeds it, and fresh oil for the refill. Opening the system twice for parts you could have done together is wasted labor. We will build the seal-and-hose kit for your lift so the repair is complete in one go.
Hydraulic fluid
When you refill, use the right oil: ISO-32 hydraulic fluid on most lifts, or Dexron ATF on some older designs — never a blend of the two. Your installation manual lists the correct capacity for your specific lift, so fill to that spec and re-check the level after you have cycled and bled the system.
Safety notes
Hydraulic parts hold a vehicle in the air on pressure and a column of oil — respect both. Relieve system pressure before you crack any fitting, cap every open port so grit stays out, and bleed the system fully before the lift carries a load. Air in the lines is what causes a lift to drift or drop unexpectedly.
Before you order
Have the data plate in front of you when you order — model, serial, and voltage if it is a power unit. Match hose length and fitting type against the old part, and remember the job includes fresh oil and a full bleed. Not sure whether you need the part or just seals? Call and we will sort it.
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.
Why buy your Challenger hydraulic fluid from Auto Lift Services
We install, inspect, and repair Challenger lifts every week — the 44840-3W is a part we handle in the shop, not a random SKU we drop-ship. The phone answers if you have a question mid-install — call 800-674-9302 — and every part ships genuine, no aftermarket substitution unless you ask for it.
About this challenger 44840 wire mesh
Sourcing the correct challenger 44840 wire mesh is not the spot a shop wants to gamble. This piece sits inside a load path the lift manufacturer engineered to specific tolerances, and a substitute that looks close but is off by even a small margin can transfer load onto a neighboring component that was not designed for it. We stock this exact part to the OEM specification the original manufacturer publishes, which is why techs who have been through a bad aftermarket cycle keep coming back to us for the same replacement whenever their next need comes up.
Technical specification & installation notes
Technical specification matches the OEM published dimensions to within manufacturing tolerance. When a shop installs the challenger 44840 wire mesh correctly, the lift returns to factory-rated performance immediately — no break-in period, no cycle-count adjustment required. The lift's safety systems (mechanical locks, hydraulic pressure relief, and electrical interlocks) treat a correctly-installed replacement exactly as they would treat a factory-original component during initial commissioning. That parity is what lets us honor warranty coverage without asking for the lift's full operating history.
Shipping & ordering
Placing an order online is the fastest path — add to cart, check out, done. If the shop needs a purchase order, net-30 terms, or a formal quote for a fleet-service contract, our accounts team handles those via email at [email protected] or by phone at 800-674-9302. Volume pricing on the challenger 44840 wire mesh kicks in at 10+ pieces on the same order for common wear items. Ask about the volume rate specifically before you check out — many fleet buyers stock 6-12 pieces at a time and the discount is meaningful over that shelf life.
Warranty coverage
Consumables and wear parts like this are covered under the manufacturer defect warranty for twelve months. Because the challenger 44840 wire mesh is a component that eventually needs replacement in normal operation, warranty coverage specifically addresses failure due to manufacturing defect, not failure due to normal end-of-life wear. Our team can help distinguish between the two on a phone call if there is any question after installation — call 800-674-9302 and describe the failure pattern; we will tell you honestly whether it looks like a warranty case.
Cross-reference & fitment
Cross-reference on the challenger 44840 wire mesh is straightforward: match the OEM part number from the lift's parts breakdown against the number on your original invoice. If the numbers match, the component fits. If your lift's parts breakdown lists a superseded or alternate number, we accept the superseded value on the phone as confirmation of fit. When a manufacturer has issued a running change during production, we track the change in our catalog so ordering by the older number automatically pulls the current-spec replacement.
