The Rotary FD220 lift adapter is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-9755-51, 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 adapter 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: ALS-9755-51
• Brand: Rotary
• Type: Genuine OEM lift adapter

The arm pad is the rubber or poly contact point between the steel arm and the vehicle's lift point. Its whole job is to grip and to protect the pinch weld or frame from the hard steel underneath. Every pad is a wear item by design — it compresses, hardens, cracks, and eventually tears or crushes flat, at which point it stops gripping and starts letting the car slide.

Replacing your lift adapter

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

If you are not sure this part matches your setup, the fastest check is the visual breakdown: open our Rotary parts lookup, pick your model, and match your part against the drawing where every item is numbered. Can't read the model plate? our guide to finding your model number shows exactly where it lives on each lift type, and we are a phone call away if you would rather have us confirm it.

Signs this part is worn out

Watch the lift hold a vehicle. With a car on the arms, look for any pad that squirms, any adapter that rocks, any arm that settles or rotates. Movement under load that shouldn't be there points straight to a worn pad, a bent adapter, a wallowed pin hole, or a loose retainer. The car sitting rock-solid is the pass; anything shifting is a part to find and replace.

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.

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.
