The Rotary FJ6180 replacement part is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7533-98S, 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 replacement part 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-7533-98S
- Brand: Rotary
- Type: Genuine OEM replacement part
- Fits: SPO12 EH-1, SPO12 EH-2
- Lift type: 2-post lift
This is a manufacturer-spec replacement part for the lift it was designed for — same dimensions, same material, same fit as the part that came off. That matters more on a lift than on most equipment, because lift parts do not work in isolation: a part that is close-but-not-quite transfers its error into whatever it bolts to, rides on, or seals against. A knock-off that is a few thousandths off might install fine and then wear its neighbors for the next five years. When you order to the published spec, the part drops in and the rest of the lift never knows anything changed.

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.
Before you install the replacement, compare it side by side with the part you removed — length, bore, thread, and mounting pattern should match exactly, not approximately. If the old part is worn out of shape, measure against the mounting points on the lift instead. A mismatch caught on the bench costs you a phone call; a mismatch caught after installation costs you the job twice.
Never modify a lift part to make it fit — no drilling out holes, no grinding down shoulders, no washers-as-spacers improvisation. A part that needs persuasion is the wrong part, and a modified part on a machine that holds vehicles over people is a liability with your name on it.

About this fj6180 nesting extension
Sourcing the correct fj6180 nesting extension is not the spot a shop wants to gamble. This piece sits inside a load path the lift manufacturer engineered to specific tolerances, and a substitute that looks close but is off by even a small margin can transfer load onto a neighboring component that was not designed for it. We stock this exact part to the OEM specification the original manufacturer publishes, which is why techs who have been through a bad aftermarket cycle keep coming back to us for the same replacement whenever their next need comes up.
Technical specification & installation notes
Cycle life on this piece depends heavily on operating conditions. In a typical commercial repair shop running 6-10 lifts per day, the fj6180 nesting extension should deliver five to eight years of service before showing measurable wear against the OEM inspection specification. In a high-volume tire or alignment shop running 20+ lifts per day per bay, expect service every three to five years. It is designed to be a serviceable component; when it does wear it wears within safe operating margins that trigger visible symptoms — drift, uneven wear, minor leakage — well before failure becomes a safety issue.
Shipping & ordering
Shipping runs 3-5 business days on standard ground to the lower 48 states. Expedited overnight and two-day options are available; call 800-674-9302 before ordering to quote expedited freight. We stock the fj6180 nesting extension in Iowa and ship same-day for orders confirmed before 2 PM Central. Orders that come in later than that or on a Friday afternoon pick up on the next business day. A tracking number gets emailed to the address on the order the moment the package leaves our dock.
Warranty coverage
Consumables and wear parts like this are covered under the manufacturer defect warranty for twelve months. Because the fj6180 nesting extension is a component that eventually needs replacement in normal operation, warranty coverage specifically addresses failure due to manufacturing defect, not failure due to normal end-of-life wear. Our team can help distinguish between the two on a phone call if there is any question after installation — call 800-674-9302 and describe the failure pattern; we will tell you honestly whether it looks like a warranty case.
Cross-reference & fitment
Alternate applications for the fj6180 nesting extension sometimes exist. Where a common part fits multiple lift models across a manufacturer's catalog, cross-reference sheets show the compatible models explicitly. If you are consolidating parts stock and want to know which of your lifts the piece covers, email the request to [email protected] with a list of the lift models in your bay — we return a compatibility grid showing which lifts accept the replacement and which need a different number.
