When a dealership service manager in central Iowa calls us about automotive two post lifts, the first question almost never comes up on the phone — it’s whether the bay can actually support one. We’ve walked into shops expecting a straightforward oil pan gasket bay and found six inches of thirty-year-old concrete, a nine-foot ceiling, and no forklift anywhere on the property. Before we quote a single lift, we run a real site survey, because the difference between a lift that lasts fifteen years and one that cracks the slab in month three comes down to numbers most people never think to measure. This is what we actually check.

Why Oil Pan Gasket Work Needs the Right Two Post Setup
Oil pan gasket jobs sound simple until you’re actually under the vehicle. The technician needs full, unobstructed access to the pan, the crossmember, and often the exhaust and transmission crossmember bolts, which means the arms and pads have to clear the sub-frame without fighting the tech for space. This is where a lot of shops make a mistake buying automotive two post lifts based on weight capacity alone and ignoring arm reach and rise height. A 10,000 lb capacity lift with short arms is useless if the tech can’t swing a pad under the pinch weld on a longer pickup or SUV that dealerships service every day.
We also look at how often the bay turns vehicles. A dealership doing steady oil pan gasket and general service work needs a two post lift that goes up and down fast and holds steady at working height without drift, because techs are in and out of that bay all day. Asymmetric arm lifts tend to work better here since they let the door swing open without hitting the column, which matters when a tech is moving in and out constantly to grab tools or a torque wrench. We spec these jobs with Rotary and Challenger units specifically because their arm geometry handles this kind of repetitive, in-and-out service work without excessive wear on the arm restraint mechanisms over years of daily use in a busy bay.
Measuring Ceiling Height Before You Order Automotive Two Post Lifts
Ceiling height kills more lift orders than anything else we see. We had a shop in Alden looking at a used 10,000 lb two post with a ceiling around 12 feet 6 to 7 inches, which is workable, but plenty of older central Iowa buildings run closer to 10 or 11 feet, and that changes which model and which overhead configuration will actually fit. An overhead-style two post needs several extra feet of clearance above the vehicle’s height at full rise, so we always measure from the floor to the lowest overhead obstruction — ductwork, sprinkler heads, light fixtures — not just to the roof deck.
If your ceiling is tight, we steer dealerships toward low-overhead or no-overhead-beam configurations instead of forcing a standard overhead unit into a space that won’t clear it. We’ve had customers shopping lifts specifically because a competing option didn’t have an overhead beam at all, and for a shop with a low ceiling, that’s often the right call rather than trying to squeeze a taller unit in. Get this measurement wrong and you’re either returning a lift or cutting into ceiling infrastructure, and neither is cheap or fast to fix once the lift is already on site.
Concrete Thickness and Slab Condition
Automotive two post lifts anchor into the slab, and the anchors are only as good as the concrete underneath them. We ask every dealership two questions before we ever schedule an install: how old is the slab, and does anyone know the actual thickness? A lot of service managers genuinely don’t know — we’ve had customers say they’d have to track down a previous property owner just to find out. As a rule, we want to see roughly 4 to 6 inches of solid, uncracked concrete with reasonable cure time behind it, and anything questionable gets a core sample or a footing plan before we install.
If the slab is thin, cracked near where the columns will sit, or poured over fill instead of solid ground, we don’t just install anyway and hope. We’ve recommended footings under lift columns in exactly these situations rather than anchoring into concrete that won’t hold torque over time. A two post lift under load puts serious lateral and vertical stress through those anchor bolts, and a bad slab shows up as creeping columns or a lift that won’t hold level within a year or two. It is far cheaper to fix this before delivery than after a lift is bolted down and loaded with a customer’s vehicle.
Delivery Access and Equipment on Site
Every site survey we run includes a plain logistics question: how does the lift actually get from the truck to the bay floor. Dealerships usually have a service drive and a dock, which helps, but plenty of independent shops don’t have a forklift at all. We’ve delivered to shops running nothing but a farm tractor with a bucket attachment, and that can work fine for getting components off a truck, but it changes our delivery scheduling and sometimes the crating plan.
We also confirm whether there’s a pit, an existing lift being removed, or other equipment already occupying the bay, because clearing that out is its own project with its own lead time. If a shop is swapping out an old in-ground lift for a new above-ground two post system, that removal has to happen and get inspected before our crew can even start layout work. Knowing this ahead of time lets us build a realistic install date instead of a truck showing up to a bay that isn’t ready.
Arm Reach and Pad Placement for Common Dealership Vehicles
Central Iowa dealerships service a wide mix — half-ton and 3/4-ton trucks, SUVs, and passenger cars — and pad placement changes with every one. For oil pan gasket work specifically, we walk through where the pads will actually sit relative to the pinch welds and the pan on the most common vehicles in that dealership’s mix. A lift with limited arm sweep might handle a sedan fine but come up short reaching lift points on a longer 3/4-ton truck, forcing the tech to compromise on pad position, which is not something you want when you’re removing a pan.
We spec arm length and reach based on the actual fleet a dealership sees, not a generic average. Shops that specifically want American-made equipment for heavier truck work often land on Challenger’s CL10 series, which we quote both with and without professional installation depending on what the customer already has for site prep. Getting arm reach right up front avoids the awkward situation of a tech improvising pad placement on a vehicle the lift wasn’t really speced to handle.
Anchoring, Leveling, and Final Inspection
Once concrete and ceiling clearance check out, the actual anchoring and leveling is where installation quality separates a lift that runs true for a decade from one that needs constant adjustment. Our crews torque anchors to spec, check both columns for plumb, and run the lift through a full cycle before we call the job done. We’ve taken calls from other shops where a two post lift was never fully installed — cables not adjusted, hydraulic lines not fully connected — and it sat half-functional for months because nobody finished the job correctly the first time.
We also check cable tension and hydraulic line integrity as standard steps, not afterthoughts, because a lift that’s slightly out of adjustment when it leaves our crew’s hands tends to get worse under daily dealership use, not better. If a dealership later relocates a bay or changes ceiling height, cables often need readjustment for the new geometry, and that’s a service call we handle directly rather than leaving a shop to figure out on their own.
Warranty Support After the Install
A lot of dealerships buy lifts through general retailers or have installs done by whoever’s available, and later find out the installer isn’t the one who can actually service the warranty. We’ve fielded calls from shops whose lift went in through a big-box retailer’s installer, and when something went wrong, there was no clear path back to a technician who actually knew the equipment. Buying automotive two post lifts directly from a company that also installs and services them closes that gap.
Because we install what we sell across central Iowa, our warranty support isn’t a call center reading a script — it’s the same crew that measured your ceiling and torqued your anchors coming back if something needs attention. That matters most in the first year, when a dealership bay is putting real daily hours on new equipment and small adjustment issues are far more common than major failures. Knowing who to call, and having that person already familiar with your specific bay, saves real downtime.
