Rotary has built two-post lifts for decades and the model lineup can get confusing when you’re just trying to buy a cable. This page is a straight model-by-model breakdown of rotary 2-post lift parts — which numbers fit which frame, what fails first on each family, and how to order the right revision on the first try. Auto Lift Services is an Iowa-based Rotary dealer and installer, and we ship rotary 2-post lift parts to shops nationwide. Same-day shipping on stocked items when you order by 2pm Central. Have your model tag photo ready and call 800-674-9302 if you want us to look up the part while you’re on the phone.
Identify your Rotary 2-post family first
Rotary uses a naming convention that tells you most of what you need. SP or SPO means symmetric (arms equal length, front and rear). SPOA means asymmetric (rear arms longer, columns rotated so the vehicle sits back in the bay). The number after is capacity in thousands of pounds: SPO10 = 10,000 lb, SPO12 = 12,000 lb, SPOA7 = 7,000 lb, SP88 = 8,000 lb. Modern SPO revisions have letter suffixes for arm generation and cable routing. Take a phone picture of the data tag on the powerside column — that plus the serial number tells us which of several revisions your lift shipped with, and it changes several part numbers.
SPO10 / SPOA10 — the workhorse 10,000 lb parts
The 10K SPO10 (symmetric) and SPOA10 (asymmetric) are the most common Rotary 2-posts on the road. Fast-movers: equalizer cables in the N378 family, the N346 hydraulic cylinder and its seal kit, the S130105 arm-restraint pin assembly, lifting-cable sheaves around N135, lock release air cylinders, complete lock ladders, and screw pads. Newer SPOA10 asymmetric frames have overhead cable routing; older revisions had it in the floor channel. Give us the serial range and we’ll match. Rubber pads and low-profile truck adapters for the arm ends are consumables — buy a spare set with any cable order.
SPO12 / SPOA12 — 12,000 lb frame parts
The 12K frames use taller columns, heavier arms, and a bigger cylinder. The core rotary 2-post lift parts here are the N342 cylinder and seal kit, longer equalizer cables scaled to the taller column, heavier lock ladders and pawl hardware, and the beefier arm-restraint components. If you have an older SPO12 or SPOA12, hose lengths were revised twice in the production run; that’s another reason to send serial with any hose or hydraulic-line order. Screw pads and pin sets are shared with several other Rotary frames, which makes stocking spares easier.
SPOA7 and SP88 — light-duty and older frames
Plenty of SPOA7 (7,000 lb asymmetric) and SP88 (8,000 lb symmetric) lifts are still working 20-30 years in. Rotary supports most of them and where OEM has gone obsolete we source ALI-recognized replacements. Cables on these frames use different diameters and end fittings than the SPO10 family — don’t cross-order between them. Lock ladders, arm-restraint kits, and complete power unit swaps are the top-called rotary 2-post lift parts for these vintages. Older power units are often cheaper to replace than to rebuild once seals go.
SPO16 / SPO18 — heavy-duty commercial parts
The 16K and 18K commercial frames are built for medium-duty trucks and use their own arm sets and cylinders. Common parts include the heavier cylinder families and their seals, extended equalizer cables, uprated pawl hardware, and the heavy-duty truck adapter sets that shipped with the lift. If you’re running one of these in a heavy-duty shop, we recommend keeping a full cable set and a seal kit on the shelf — freight for a specialty commercial part is where the emergency bill really lands. On the 16K and 18K frames, adapter sets tend to be lift-specific rather than shared, so build a dedicated small-parts kit per lift instead of a shared shop kit.
Cables, locks, and arm restraints — the safety-critical set
Every 2-post safety-critical part we ship is OEM or ALI-recognized equivalent. That covers cables (N378 family for SPO10, others for other frames), lock ladders and pawl hardware, arm-restraint gears and pins (S130105 and related), and the release cables that tie the columns together. Inspection cadence is every 90 days per ALI; replace cables at the first sign of broken wires, kinks, corrosion, or unequal arm travel that doesn’t respond to re-tension. Do cables in pairs on symmetric lifts. Arm-restraint gears round off from being ridden — replace the gear and pin together.
Hydraulic cylinders, hoses, and power units
Cylinders are the longest-lived component on a Rotary 2-post. N346 (SPO10 family), N342 (SPO12 family), N380 and current-generation replacements typically go 10-15+ years. Most ‘cylinder problems’ are actually seal kits, worn plungers, or contaminated fluid. Full cylinders, seal kits, and hydraulic hoses are all stocked. Power units seep before they fail — motors get tired around the decade mark and solenoids stick. New units drop in cleanly and reset the whole hydraulic side. Order the unit with fresh AW-32 or AW-46 fluid so you can do it in one trip.
Order rotary 2-post lift parts the fast way
Best combination: model tag photo + serial number + a photo of the broken part. From there we can pull the right rotary 2-post lift parts in a minute. You can also browse our stocked catalog directly at Rotary aftermarket parts or search a specific number in parts lookup. If the repair cost is climbing past the value of the lift, our 2-post lift buying guide walks through what’s currently available new. Call 800-674-9302 for a live look-up. We install and service Rotary equipment every week and stock the fast-movers on the shelf, so you’re not waiting on a distributor to open a box before yours ships.
