The Rotary FJ7866-1 lift arm pad is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-9785-05, it is the genuine Rotary part — same part number, same fit, and same working specification as the one already on your lift. Ordering the Rotary lift arm pad from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same.

The structural parts are what actually touch the vehicle and carry it — the arms and their pads, the adapters that reach a pinch weld or frame rail, the carriage that rides the column, and the hardware that holds it all together. They turn the lift's motion into a stable hold on the car. Every one of them takes the full weight and every bit of the shock when a vehicle settles, which is why they wear, spread, and crack.

Replacing your lift arm pad

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. Full step-by-step: how to replace car lift arm pads.

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 Rotary 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 this part is worn out

Inspect welds and steel for cracks. Wipe the arms, carriage, and column joints clean and look hard at every weld seam and stress corner — a hairline crack at a weld toe or a bend radius is the start of a failure. Cracks near arm pivots, at carriage gussets, and around anchor points are the ones that matter most. Any crack in a load-bearing weld takes the lift down.

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.
