The Rotary FC5818-24 lift adapter is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7531-85, 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.

Adapters take a beating because they're the parts techs handle every day — stacked, swapped, dropped, and driven over. A bent lip, a mushroomed top, or a cracked weld on a frame-cradle adapter comes from that daily handling as much as from load. Because they're small and get tossed in a pile, they're easy to grab without a second look — which is exactly how a bent one ends up under a car.

Replacing your lift adapter

Replacing an adapter is usually drop-in, but the fit is everything: the new adapter has to reach the correct height, seat square on the pinch weld or frame, and clear the rocker. Set it in place and load-test it before trusting a car to it. The step-by-step guide covers how to confirm it's seating right. 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

The surest way to get the right part is to work from your lift's own breakdown. open our Rotary parts lookup, choose your model, and every part is mapped on the drawing with its number and price. If you cannot find the model plate, our guide to finding your model number explains where each lift type hides it, and our phone line is open if you want a hand.

Signs this part is worn out

Start with the pads. A good pad is thick, square, and grippy; a worn one is crushed flat, cracked through, torn at the edge, or hardened smooth so it no longer bites. If a pad is missing chunks, oil-soaked, or compressed past half its original height, replace it — a slick or crushed pad lets the vehicle's lift point slide right off the arm.

Parts commonly replaced at the same time

Order structural parts in the set they belong to. A single fresh pad among three flat ones does not restore even support, and the pins and hardware around a worn part are usually due too. We keep the right versions for your lift and can assemble the full contact-point kit in one order.

Safety notes

Do not overlook the structural wear items just because they are simple. A worn arm pad or a cracked ramp weld can let a vehicle walk or drop, and they fail quietly until the day they do not. Inspect contact points every service and replace anything crushed, cracked, or bent before the next lift.

Before you order

A little prep saves a wrong part: confirm model and serial, count how many you need, and match the mounting against what came off. Pads and adapters wear as a group, so ordering the set is usually the smart move. Ask about the companion hardware while you are at 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.
