The Cedar Rapids overlanding builder who called us last winter had a lifted mid-size truck, three project rigs in various states of disassembly, and a habit of getting under vehicles on jack stands that his wife had finally put a stop to. He needed a garage two post lift that could handle a fully loaded expedition rig, clear the ceiling of a converted pole barn, and let him keep doing his own annual state inspections without dragging vehicles to a shop. This is his story — the site survey, the ceiling math, the arm choice, install day, and what we’d do differently if we ran the whole project again from scratch.
Twelve- and fifteen-thousand-pound two-post lifts sized for lifted trucks, overlanders, and off-road builds — full install support across Iowa.
The customer and the build shop
The building was a 40-by-60 pole barn originally built for tractor storage, converted in 2018 to a home shop. Ceiling: nominally 14 feet, but with LED shop lights, an overhead fan, and heat ducting hanging down to 12 feet 6 inches at the low point. Slab: unknown thickness, poured with the original building in 2003. Owner: a fabricator by trade with a background in fleet maintenance, so not a first-time lift buyer, but a first-time home installer.
The trucks were the design constraint. His daily driver was a Tacoma with a three-inch lift and roof rack — measured at 84 inches to the top of the rack. His project rig, a first-gen 4Runner build, was even taller with a rooftop tent that comes off before it goes in the shop. His wife’s overlanding vehicle, a Sprinter conversion, was completely out of scope for a garage two post lift; that stays on the ground. But he wanted a lift that could raise all three trucks to comfortable working height without ripping a light off the ceiling. That single spec drove every subsequent decision on the project.
Site survey and slab assessment
We drove out to the property in November with a rebar locator, a Schmidt hammer, and a laser measure. First stop: the slab. The rebar locator showed #4 rebar on 18-inch centers, which is above spec for most residential slabs and told us this building was over-engineered for tractor loads. The Schmidt hammer estimated slab strength between 3,800 and 4,200 PSI — comfortably above the 3,000 PSI minimum. We also confirmed thickness at 4.5 inches by drilling two exploratory holes near where the lift columns would land, patched afterward with structural epoxy.
Next: the ceiling. We laser-measured the lowest point in the intended lift zone (a duct crossing the space at 12 feet 4 inches) and the working ceiling elsewhere (13 feet 8 inches to structural). This gave us clear numbers to work with. Then we walked the drive-in path — 20 feet from the roll-up door to the intended lift position — and confirmed the vehicle could enter, position, and exit without maneuvering around obstacles. Site surveys catch problems in an hour that would cost thousands to fix after install. For any garage two post lift installation more complicated than a rectangular garage, we recommend one.
Ceiling clearance math for lifted trucks
The critical number for a lifted-truck garage two post lift is total working height clearance, which is: ceiling height minus (vehicle roof height when raised) minus (lift crossbar clearance if overhead) minus (a safety margin). For this project: 12 feet 4 inches ceiling minus 7 feet Tacoma-with-rack (raised 6 feet on the lift = 13 feet to top of rack) — the math clearly failed for an overhead design. We would have needed either a lower rack or a baseplate lift.
We went baseplate. Rotary SPOA10 baseplate, 10,000-pound capacity, no overhead crossbar. That let the Tacoma raise to 6 feet at the frame, which puts the top of the rack at 13 feet — right at ceiling but with no crossbar in the way. The 4Runner build (no rack when in the shop, removed for storage) had 18 inches of clearance to spare. The customer accepted that the Tacoma would raise only to 4.5 feet if the rack stayed on — not full height, but enough for wheel and undercarriage work. This is the kind of trade-off you can only make by doing the math with real vehicle measurements, not spec-sheet averages. Every serious garage two post lift install for a lifted-truck owner walks this same path.
Choosing arms for wide frames
Standard two-post lift arms are designed for passenger cars and typical light trucks. Lifted and overlanding builds add three complications: wider frames, taller ride heights that push the pad reach outward before it goes up, and non-standard jack points because of rock sliders, skid plates, and bumper armor. Long-reach arms — specifically, the manufacturer’s optional heavy-duty asymmetric arms — solve most of these.
We speced Rotary’s LR asymmetric arm package. Front arms extend to 32 inches, rear arms to 60 inches. On the customer’s 4Runner with rock sliders welded to the frame rails, the front arm reached the factory jack point cleanly without touching the slider. On the Tacoma, we mapped four possible pad positions per side and picked the two that worked with the truck at its current lift height. Documenting pad placement matters more on off-road builds than on stock vehicles because the jack points may be modified or hidden by armor. We literally taped location marks under each truck during the install so the owner would remember where to place pads. Six months in, he still uses the marks.
Install day — what actually happened
Install day was a Tuesday in early December. Two-person crew, 8 a.m. start. Columns off the trailer, laid out, base plates positioned per install manual. Anchor holes drilled — six per column, half-inch by 4-inch embedment. Anchors set with expansion sleeves, torqued to 90 foot-pounds per the manufacturer spec. First column plumbed and secured by 10 a.m. Second column done by 11.
Lunch, then hydraulic system. We routed the baseplate hose in the low-profile channel between the columns, connected to the power unit on the driver’s column. Filled reservoir with lift fluid, bled the system through three cycles empty. Cable tension: adjusted equalizer cables by hand, then verified with a torque check on the equalizer chain. First lift with the customer’s Tacoma at 3 p.m. Cycled the lift five times empty and three times loaded before signing off. Total install time: seven hours. The customer signed the paperwork, we walked him through daily operation and the ninety-day inspection routine, and we were on the road home by 4:30 p.m. This is a normal install day for a straightforward garage two post lift with a proper site survey behind it.
Annual state inspection workflow after install
Iowa doesn’t require annual vehicle safety inspections for personal vehicles, so “state inspection” here means his out-of-state customer work — occasional friends bringing rigs from states that do require them. Having a lift changes the workflow completely. Under-vehicle inspection points that used to take an hour on jack stands now take fifteen minutes. Brake line inspection, exhaust system, differential leaks, ball joint play, tie rod condition — all done from a standing position on a raised vehicle.
He worked out a routine: raise, walk both sides looking for obvious leaks, engage safeties, get under and do the checklist top to bottom. He clocks it at twenty-two minutes per vehicle now, down from an hour and change on stands. That’s a real productivity gain, but the bigger gain is safety. Nobody is under a vehicle on jack stands anymore. For an off-road builder who does his own inspections, his own service, and his own upgrades, a garage two post lift changes not just the speed of the work but the risk profile of every job under a raised vehicle. It’s the same reason professional shops require lifts — no responsible tech works on stands if a lift is available.
What we’d do differently on the next off-road build install
Two things. First: we’d spec longer air lines for shop tools before install day, not after. The customer had to run a new air line to the lift bay a month later because his existing drops were positioned for tractor work. It’s a small thing, but it delayed a couple of jobs and would’ve been free to add during install. Every off-road install we do now includes an air-line and power-drop planning conversation up front.
Second: we’d have brought a taller ladder. The pole barn’s structural ceiling is 14 feet, and adjusting light fixtures out of the lift’s swing path took longer than it should have because our 10-foot ladder wasn’t tall enough to reach comfortably. Small logistical stuff — but on any garage two post lift install in a converted pole barn or high-bay building, plan the vertical access too, not just the horizontal footprint. Overall the project was a success. The customer is a year in, has serviced all three rigs multiple times, done two annual inspection cycles for out-of-state friends, and hasn’t touched a jack stand since. That’s the outcome we aim for on every install we do.
