The BendPak HD-27 is a 27,000-pound four-post lift built for medium trucks, buses, motorhomes, and the heaviest fleet vehicles that still fit through a commercial shop door. When one of these needs service, the calculus on bendpak hd-27 parts is different from a lighter four-post — components are larger, cables are heavier, cylinders are bigger, and downtime on a bay this size is expensive. This guide covers the HD-27’s defining features, common wear items, how to identify your exact revision, cable and cylinder service, and installation notes.

What the HD-27 is and where it fits
The HD-27 is BendPak’s heavy-duty four-post lift rated at 27,000 pounds, designed for medium-duty trucks, small buses, motorhomes, ambulances, and other Class 4 through Class 6 work vehicles. Its defining feature is the combination of a heavy-gauge four-column structure with industrial-scale safety locks and a hydraulic cylinder scaled to the load class. Shops that run one usually run it hard, which means the bendpak hd-27 parts conversation leans toward planned inspection and preventive replacement rather than crisis repair. It is a lift you baseline once a year and keep on schedule.
Common wear items and inspection intervals
ALI recommends 90-day inspection on commercial lifts and the HD-27 lives inside that cadence. The high-frequency bendpak hd-27 parts are heavy lifting cables, latch bars and springs on the industrial lock system, air-line fittings and release cylinders, screw pads, and drive-over approach ramps. Annually: hydraulic fluid, cylinder seal kits at the first sign of weep, and rolling jack service if the lift is equipped. Because the cables and cylinder on an HD-27 are larger than on a passenger-class four-post, freight matters — consolidating your annual service order into one shipment is a real cost lever, not a small one.
Identifying your HD-27 the fast way
BendPak has produced the HD-27 across several revisions and the serial number tells us which cable, cylinder, and hydraulic hose to send. The data tag lives on the powerside column near eye level. Snap a phone picture with the serial visible and send it with your order — that single step is the fastest way to guarantee correct bendpak hd-27 parts on the first try. BendPak’s own Support > Replacement Parts pattern uses the same serial-based lookup, and our parts desk uses it too. If the tag is missing or unreadable, a photo of the whole lift plus year of purchase usually narrows the revision enough to pull the right parts.
OEM vs aftermarket on a heavy-duty lift
On a lift that carries 27,000 pounds, we default hard to OEM or ALI-recognized equivalent for anything safety-critical: cables, lock pawls, springs, and cylinder assemblies. There is no meaningful savings on aftermarket safety parts at this scale, and the liability calculation is not in your favor. For non-safety wear like screw pads, rubber ramp bumpers, hydraulic fittings, and adapters, aftermarket equivalents are fine and can be much cheaper. Our broader take on this trade-off is in the BendPak lift parts buyers guide.
Cables, cylinders, and locks for the HD-27
The HD-27 uses four heavy lifting cables running through overhead sheaves to equalize load across the columns. Cable retirement criteria are the same as any four-post — broken wires, kinks, corrosion, unequal runway travel — but the physical parts are noticeably larger. Replace all four bendpak hd-27 parts in the cable set together; the labor is the same and matched wear is the whole point. The HD-27’s hydraulic cylinder is a long-life component; the first repair is almost always a seal kit rather than a full cylinder. Industrial lock ladders and pawls are inexpensive to keep on the shelf and belong there. Cable and cylinder theory in general is covered in our car lift cables guide and hydraulic cylinder for car lift references.
Installation and service notes at 27,000 pounds
A four-post lift does not have to anchor to the slab, but the HD-27 loaded footprint concentrates real weight and the concrete under it has to be sound, level, and thick enough. If your bay was poured to a lighter spec, verify with a concrete inspection before installing or relocating. When you re-cable, level the runways carefully and cycle the lift several times under progressive load to seat new cables before returning it to service. Clean, dry air at the FRL is not optional on a lift this size — wet or low shop air is the number one reason locks refuse to release.
Sibling BendPak models to consider
If the HD-27 is more than you need, BendPak’s HD-14 covers 14,000 pounds for pickup-class commercial work and the HDS-18E covers the middle ground. If you need even more capacity, the mobile-column category from other manufacturers is the usual step up. Parts do not cross between capacity classes on any four-post product line — an HD-27 cable is not an HD-14 cable — but the service intervals and inspection logic are the same across the family. For the full four-post product logic see the 4-post lift parts guide.
Ordering bendpak hd-27 parts
Best order: photo of the data tag with model and serial visible, plus a photo of the broken part. From there we pull the right bendpak hd-27 parts in a minute and get them on a truck the same day for stocked items. Browse the catalog at other aftermarket lift parts or search a specific number in parts lookup. If a repair bill is climbing past the sensible line, we will say so plainly rather than write the ticket. Call 800-674-9302 for a live look-up — we ship bendpak hd-27 parts daily out of Iowa and the parts desk answers in person, not through a menu tree.
