Last fall we installed a pair of automotive two post lifts in a shop just outside the Quad Cities for a guy who builds overland rigs — 4Runners with roof tents, Tacomas on 35s, a Gladiator with a full rack and an awning bolted to it. He does his own oil changes, diff service, transfer case fluid, and coolant flushes, and he was doing all of it on ramps and jack stands in a building with a 14-foot ceiling that he assumed was plenty. It was not plenty, and figuring out why turned into a two-week conversation about roof tents, door swing, and the difference between the height of your building and the height you actually get to use. Here is how that job went.
Baseplate and overhead models from Rotary, Challenger, BendPak, and Atlas. If you run tall vehicles with racks or tents, talk to us about clearance before you order — it is a five-minute call that saves a return shipment.
The Building Looked Big Until We Measured the Right Things
His shop was a 36×48 post-frame building with what the builder called 14-foot walls. The peak of the truss was higher than that, and standing in the middle of the floor it felt cavernous. But the lowest obstruction in the bay he wanted to use was a run of 4-inch conduit and a pair of LED strip fixtures hanging on chain at roughly 11 feet 8 inches. Then there was a purlin at the bay edge and a garage door track that swept back into the space when the door opened.
Usable clearance was not 14 feet. It was 11 feet 8 inches at the worst point, and it was less than that in the door-swing path. That is the single most common mistake we see when people shop for automotive two post lifts online: they measure to the ridge, order an overhead model, and discover on install day that the crossbar collides with a light fixture. We measure to the lowest thing in the volume the lift will occupy, then subtract for the vehicle. A 4Runner with a roof tent is pushing 7 feet 6 inches tall before it leaves the ground. Add even 40 inches of lift travel to get under it comfortably and you are over 10 feet 10 inches of occupied space. That left him almost no margin under a crossbar.
Why We Went Baseplate on This Job
The answer was a baseplate configuration. Removing the overhead crossbar removed the ceiling constraint entirely. His tallest rig could go as high as the carriages would carry it and the only limit became the roof structure itself, which was 24 inches above the light fixtures anyway once you got away from the conduit run.
He was hesitant at first, and his hesitation was reasonable. He had read that baseplate designs put a hydraulic line and equalization cables in a channel across the floor and worried about rolling a heavy transmission jack or a 100-pound diff housing over it. We walked him through the actual profile — the cover on the unit we specced is under an inch and a half at the peak with a ramped edge on both sides. A creeper rolls over it. A floor jack rolls over it with a nudge. What genuinely does not love it is a low-profile aluminum jack with three-inch wheels, and he owned one of those, so we noted it and moved on. For a shop where every vehicle on the pad is tall by definition, giving up a perfectly flat floor to gain unlimited overhead is not a close call. Baseplate automotive two post lifts exist for exactly this scenario and they solve it cleanly.
Door Swing, Column Placement, and the Geometry Nobody Sketches
The second constraint was the overhead garage door. When it opened, the panels rolled up and back along a horizontal track that intruded about nine feet into the bay at roughly 12 feet of height. That intrusion sat directly over where the front of a vehicle would park on a centered layout.
We solved it by pushing the entire lift footprint back. Two post installs need drive-in approach room, and the rule of thumb we use is that you want the front tires to land two to three feet past the columns for a symmetric layout, more for an asymmetric one. Shoving everything rearward cost him some approach room at the door, which meant a longer wheelbase truck now needs a bit of a swing to line up. He was fine with that. What he was not fine with — and this is the part people never sketch out — was the vehicle door swing at height. On a lifted 4×4, the rocker sits high already. Put it four feet up on a lift and the door opens over the top of the column base. On a symmetric layout with the columns dead center, a full-size truck door can catch a column. Asymmetric geometry rotates the columns and moves the vehicle rearward specifically to fix this, and for a builder who is climbing in and out of cabs to run the engine, check a transfer case shifter, or grab a tool off the seat, that clearance is used a dozen times per session.
Fluid Service Is a Different Job Than Brake Work
People assume a lift is a lift. It is not, and fluid service has its own requirements. Oil changes, diff fluid, transfer case fluid, and transmission service all mean the tech is standing underneath with a drain pan, a fluid pump, and a torque wrench, working with both hands over their head.
That drives two decisions. First, lifting height matters more than for tire or brake work. You want to stand up straight under the rig, not hunch. A full-rise two post that carries the pads to 72 inches or more puts a truck’s frame rails at a comfortable working height for a six-foot person. Second, arm reach and pad configuration matter, because 4×4 frame rails and rock sliders are not in the same place as a unibody pinch weld. Most lifted trucks and body-on-frame SUVs get lifted at the frame, which means you need arms that reach inboard and pads tall enough to clear a slider or a skid plate. We shipped his unit with a set of stackable adapters — three-inch and six-inch pucks — because the Gladiator with the full-length skid needed the extra height and the 4Runner did not. Fluid work also means fluid on the floor, which means the baseplate channel gets oily. We told him to wipe it down after big jobs. Gear oil that soaks into the channel and then gets tracked across the floor is a slip hazard and a maintenance nuisance on any of the automotive two post lifts we sell.
The Concrete Conversation Went Better Than Usual
Post-frame buildings around the Quad Cities and eastern Iowa are hit or miss on slab. Some are poured properly with a reinforced 5-inch pad. Some are a 3.5-inch floating slab that was never designed to hold anything heavier than a lawn tractor. We do not guess. We core.
He got lucky. The building was five years old and the original owner had spec’d a 5-inch pour with fiber reinforcement across the whole footprint, and our two test cores came back consistent. Anchoring was straightforward: wedge anchors set into clean, vacuumed holes, torqued to spec, with more than the required edge distance from the nearest control joint. Where we did have to work was leveling. The slab had a deliberate drain slope of about a quarter inch per foot running toward the overhead door, which is smart for washing a truck and annoying for setting a lift. Both columns needed shimming to come plumb, which is normal work but it is real work, and we set the shim stack, re-checked plumb with a four-foot level on two faces of each column, and then re-torqued the anchors. We told him to re-torque again after thirty days. If you are pricing automotive two post lifts and the quote does not mention shims, coring, or anchor torque, the installer has not thought about your floor yet.
What He Would Do Differently, and What We Told Him
Six months in, his only regret is capacity. He bought a 10,000 lb unit, which is more than enough for a 4Runner or a Tacoma even loaded with recovery gear. But he has since taken in a friend’s F-250 with a flatbed and a welder, and that rig is knocking on the door of his rated capacity once you account for the bed and the tank. Going to a 12,000 lb model would have cost meaningfully more up front but would have covered him for the heavier stuff.
Our advice to anyone in the off-road and overland world is to size capacity for the biggest thing you might realistically touch, not the biggest thing you own today. Builders acquire projects. The other thing we told him: buy from someone who stocks parts. Cables stretch, lock ladders wear, cylinders eventually weep, and a lift with no parts pipeline becomes a very expensive column of steel. We keep cables, cylinders, arm restraints, lock dogs, and hydraulic components for every major brand in stock.
