Buying car lift parts is only easy when you already know your lift inside and out. For everyone else, it’s a maze of legacy part numbers, brand rebrands, aftermarket knockoffs of varying quality, and cables that look identical but are cut to different lengths. We’re an Iowa-based commercial lift dealer, installer, and service company; we sell new lifts from Rotary, Forward, Challenger, BendPak, Atlas, and PKS, and we stock parts for all of them plus a lot of older brands. This buyer’s guide is the honest version we’d give a shop owner over the parts counter: what actually wears out, how to identify your lift, and when OEM is worth it versus when it isn’t.
The five parts that fail on almost every lift
Regardless of brand, five families of car lift parts come up over and over in service calls. Equalizer cables and lock-release cables stretch, fray, and eventually fail on any two-post or four-post lift with enough cycles. Lock ladders and lock latch springs wear from repeated engagement. Arm restraint gears (or the pins on older lifts) round off. Hydraulic cylinders lose seals somewhere between year eight and year fifteen depending on fluid maintenance. Power units either burn a motor or drop pressure through a tired valve. If you’re doing preventive maintenance across a fleet, budget for cables at year 7-10 and cylinder seals at year 10-15.
OEM vs aftermarket car lift parts
Our rule is simple: safety-critical parts get OEM, comfort parts can go aftermarket. Cables, locks, arm restraints, cylinders, and hydraulic hoses are safety-critical. The load path of a lifted vehicle runs through them, and the manufacturers publish specific spec-tested part numbers for a reason. Rubber pads, plastic column covers, latch handles, adapter stack-ups, and decals are comfort. On the comfort list, aftermarket saves real money and the quality is usually fine. On the safety list, we won’t sell you a bargain cable made overseas with unspecified end fittings. Browse our brand pages for Rotary parts and Challenger parts to see how we mark each item.
How to identify your lift when the tag is gone
The single biggest reason shops receive the wrong car lift parts is misidentifying the lift. Every lift has a data plate with the model and serial number, usually inside the driver-side column at eye level, sometimes on the crossbar. If the tag is painted over or missing, we can almost always ID the lift from four photos: front-quarter view of a column, a close-up of the top crossbar, a shot of the lock ladder, and a shot of the arm pivot. Cable end fittings, lock ladder shape, and arm restraint style are brand fingerprints. Send those photos to our parts desk and we’ll ID it before you buy.
Rotary and Forward parts
Rotary is the largest installed base in North America and Forward is its sister brand. Since VSG consolidated Forward under Rotary Solutions, a lot of Forward SKUs cross directly to Rotary equivalents. On both brands, the wear items that come up most often are lock-release cables, arm restraint gears (mechanical or powered), and the plastic latch handles that snap. Full parts catalogs live at rotary aftermarket parts. Rotary and Forward keep OEM lead times reasonable, and we stock the top wear items in Iowa for same-day shipping.
Challenger lift parts
Challenger is the other major U.S. brand and the parts landscape looks different. Challenger runs a separate part-number system from Rotary and cross-references are rare. On Challenger two-posts (CL10, CL12, CL16), the parts we see most often are equalizer cables, lock ladders, and the specific Challenger arm restraint dogs that are model-year sensitive. On Challenger four-posts, the sliding jack rails and roller kits are the wear points. Full catalog at challenger aftermarket parts. Challenger parts occasionally have longer factory lead times than Rotary, so we stock the top items for popular models.
BendPak, Atlas, and other budget brand parts
BendPak and Atlas serve the home and light-commercial market, and their parts pipelines are generally good. BendPak in particular publishes clear parts diagrams. Where shops get tripped up on BendPak and Atlas car lift parts is that the same model number can hide two or three revisions with different cable lengths or different arm hardware. Serial number date-of-manufacture matters. We carry BendPak and Atlas parts on request through our general aftermarket channel. For older or off-brand lifts we still sell parts for, check other aftermarket lift parts.
Cables, cylinders, and lock lifespans
Real-world lifespans from our service book: equalizer cables on a busy commercial two-post average 7-10 years before we recommend replacement, longer on a low-cycle home lift. Lock-release cables often go first because they’re smaller diameter and see cable-flex fatigue every cycle. Hydraulic cylinders in a dry, temperature-stable shop can go 15+ years on the original seals; cylinders in an unheated pole barn or a wash bay drop closer to 8-10. Power unit motors and lock-latch springs are essentially replace-when-they-fail parts. Keeping ATF or ISO 32 fluid clean is the single biggest lifespan lever on the hydraulic side.
How to actually get the right car lift parts
Between the brand-specific catalogs above and the site-wide search, most shops find what they need. When the model isn’t obvious, use the photo trick: driver-side column tag, top crossbar, lock ladder, arm pivot. Start at the parts lookup, filter by brand or type, and if a part isn’t listed, our parts desk can source almost any legacy item that’s still in production. We’re honest about lead times before you order and we don’t push a substitute we wouldn’t run on our own service trucks. Call the parts desk at 800-674-9302 and we’ll get you the right car lift parts the first time.

Frequently Asked Questions
How do I know what car lift parts to order?
Start with the brand and model from the serial tag on the column or frame, then identify the component (cable, cylinder, arm restraint, lock) and where it sits on the lift. If you have the OEM part number from a manual, use it. If not, our parts team will match it from photos and your model.
Are aftermarket car lift parts safe?
Quality aftermarket parts from the same suppliers who manufacture for the OEMs are safe and often identical mechanically. The risk is the cheap end of the market – no traceability, wrong specs. We stock aftermarket that meets or exceeds the original, and we vet every supplier.
How long do car lift cables and cylinders last?
Equalizer cables typically last three to seven years in shop use, longer in home garages. Hydraulic cylinders can run fifteen years or more with clean fluid and can often be resealed instead of replaced. Locks and pins depend on cycle count.
What parts should a shop keep on the shelf?
For a fleet of two-post lifts, keep at least one equalizer cable set, one lock-release cable set, and a seal kit for the cylinder family you run. That covers the failures that put a bay out of service. Call 800-674-9302 for a shelf list per model.
