The Challenger 1251042060 hydraulic cylinder 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 cylinder 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: 1251042060
• Brand: Challenger
• Type: Genuine OEM hydraulic cylinder
• Fits: SX14/SX14R

A hydraulic lift that won't hold height is telling you something before it fails outright. Drift-down, a spongy feel, milky fluid — these are early warnings, and the cheap fix is now. Ignore them and a weeping seal becomes a scored barrel becomes a whole cylinder; a tired pump becomes a burned-up motor. Worse, a lift that sags under load is a safety problem, not just a maintenance one.

Seals and hoses age on two clocks at once: cycles and years. A cylinder seal wears from the miles the rod travels; a hose gets brittle just sitting in shop heat and cold. Run dirty fluid and you speed both up, because grit scores the barrel and the rod and shreds seals from the inside. Most lifts that pump every day start weeping a seal somewhere in the eight-to-fifteen year range.

Replacing your hydraulic cylinder

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. Full step-by-step: how to replace a 2-post lift cylinder.

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 of a hydraulic problem

Look under and around the whole loop for evidence, not just the obvious drip. Trace a puddle back uphill — fluid runs, so the leak is above where it pools. Check fittings, the reservoir seam, the pump-to-reservoir gasket, and the base of the cylinder. A weep that only shows under full pressure won't appear until you take the lift to max height and hold it.

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

Most 2-post and 4-post lifts run hydraulic oil equivalent to ISO-32; some older units were filled with Dexron ATF. Check what your lift currently uses and do not mix the two — and defer to your lift's installation manual for the exact fill capacity, since it varies by model.

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.

Confirm this is the right part before you order

Lift manufacturers revise parts mid-production without changing the model name, so the same lift bought two years apart can take two different revisions of the same component. Before you order, find the model plate on the lift — on most 2-post lifts it rides on one of the columns at eye level, on 4-post lifts it is usually on a column or the power-unit side runway — and note the full model number and serial. The serial dates the lift to a production run, and that is what decides which revision fits.

If the plate is painted over or missing, take a photo of the part you are replacing next to a tape measure and send it to us. Between the dimensions, the mounting pattern, and what lift it came off of, we can almost always identify the exact part before you spend money on the wrong one.
