The Challenger A2403-DPC column component 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 column component 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: A2403-DPC Brand: Challenger Type: Genuine OEM column component A worn structural part is the difference between a car that sits solid and one that slides off a lift arm. A crushed pad, a bent adapter lip, an egg-shaped pin hole — each one lets the contact point shift under load, and a vehicle that shifts on the arms is a vehicle that can come off them. These parts are inexpensive next to the bodywork of a dropped car, or the person standing beside it. Related parts for this lift The parts below are commonly ordered alongside this one — cables, sheaves, seals, and hardware wear on similar schedules, and most repairs go faster when the whole set is done in one visit. Challenger A2403 Cl10A Column Bundle Challenger A2403-DPQC Column Bundle Cl10A W/dp/qc Challenger A2403-QC Cl10A Column Bundle W/qc Replacing your column component Ramp and approach-part replacement is straightforward, but the part has to sit flush and lock where it should so it can't kick out under a car driving on. Check the hinges, stops, and retainers as you go. Because it's load-bearing at drive-on, the full procedure is worth following before you use it. 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 this part is worn out Go over the column hardware and anchors. Every anchor bolt should be tight and the base plate flat to the floor — a column you can rock, or an anchor backed out with a gap under the plate, is a serious problem. Check arm-pin retainers, gate stops, and fasteners for looseness, stripped threads, and missing pins. Loose column hardware lets the whole structure move under load. Parts commonly replaced at the same time Contact and locating parts usually wear as a group, so when you order this one, think about the set — the other three pads, the adapters that go with them, the pins and hardware that mount them. Doing the full set keeps the lift even and saves a second order. We will pull the matched group for your model. Safety notes Structural parts carry the vehicle's weight and locate it safely on the lift, so worn or damaged ones are a drop risk. A crushed arm pad, a bent ramp lip, or an egg-shaped mounting hole lets a load shift where it should stay put. Replace them before they move, and never load a lift with a compromised contact point. Before you order Have your model and serial handy, and think in sets: four arm pads, the matching adapters, the hardware that mounts them. Ordering the full set keeps the lift even and saves a second order. Send a photo of the old part if you are unsure which version your lift takes. 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.
