When a third-generation shop on the Iowa-Missouri border called us about replacing a lift their grandfather bought secondhand back when the building was still a implement dealership, the question wasn’t really about brand or color — it was whether to sink money into automotive two post lifts that are decades old or start over with something new. That’s a question we field constantly at Auto Lift Services, and the honest answer depends on your bays, your work, and your budget. If you’re doing restoration and metal work, the lift underneath that project car matters as much as the welder in your hand, and we’ve installed enough of both old and new to walk you through the real tradeoffs.

Why Restoration Shops Face a Different Calculation
A general repair shop swaps a lift every fifteen to twenty years without much drama. A restoration and metal work shop is different — the car sits up on the lift for weeks, sometimes months, while a floor pan gets replaced or a frame gets massaged back into shape. That means automotive two post lifts in a restoration bay take a different kind of abuse than a lube shop’s equipment. Arms get cranked out to full extension and left there. Weight sits unevenly while a quarter panel is off. Anyone who has fielded a call about a lift bouncing on the way down, or one post lifting slower than the other, knows that uneven loading over time is usually the root cause, not a bad part.
That’s why we tell family shops considering a used unit from an estate sale or an auction that the history of how it was used matters more than the sticker price. A ten-year-old lift that spent its life doing quick oil changes is a very different purchase than a ten-year-old lift that spent its life holding half-disassembled trucks for weeks at a time. We’ve gone out to inspect lifts that are approaching thirty years old where a post had rotted through, and the customer just wanted an honest answer on whether it was worth saving or time to buy new. Sometimes it is worth saving. Often it isn’t.
Real Dimensions: What Actually Fits Your Bay
Before anyone commits to automotive two post lifts, we ask for the numbers on the building, not just the truck they want to lift. A typical asymmetric two-post runway needs roughly 12 feet of clear width and closer to 14 feet of overhead clearance for a full-rise unit, though low-ceiling and low-rise versions exist for older buildings with 10 to 11 foot ceilings common on farms and small-town Main Street shops along the border. Post-to-post spacing on most 9,000 to 15,000 lb units runs in the 100 to 136 inch range depending on the model, and that spacing has to clear both the widest vehicle you’ll lift and the columns or walls around the bay.
We’ve had customers pouring new concrete ask us for post location, distance from the front and side walls, minimum overhead height, and where to leave the 220V run before the crew shows up to pour — and that’s exactly the right order of questions. Get the anchor bolt pattern and control joint placement wrong and you’re either cutting concrete later or living with a lift that’s off-center in the bay. If you’re restoring long-wheelbase trucks or full-size classics, don’t just measure the car — measure with doors open and mirrors out, because a symmetric or wide asymmetric configuration gives you more working room around the vehicle than a narrow low-cost unit will.
The Case for Buying New
New automotive two post lifts come with a few things a used unit simply can’t offer: a warranty, current safety engineering, and a clean paper trail on load history. For a shop doing heavy metal work — cutting out floor pans, swapping subframes, doing bodywork that shifts weight around unpredictably — that safety margin isn’t a luxury. Rotary and Challenger both build asymmetric and symmetric configurations in capacities from 9,000 lb up through heavy-duty commercial ratings, and a new unit lets you match the lift to the actual gross weight of what you’re restoring rather than hoping an old lift’s decals are still accurate.
New also means predictable service. When something goes wrong on a lift we installed, we know the arms, the cylinders, the cable routing, and the control valve without guessing. On an inherited or auction-bought lift, we’re often diagnosing a mystery before we can even quote the repair. If your shop plans to keep doing this work for another twenty years — third generation and beyond — the new lift usually pencils out cheaper over its life than nursing along equipment nobody can get parts for anymore.
The Case for Buying Used
That said, used isn’t automatically the wrong call. A well-maintained used two-post from a dealership or fleet shop that’s being upgraded can be a legitimate bargain, especially for a family shop watching every dollar. We’ve moved lifts between locations for customers plenty of times — disassembling a unit, trailering it, and reinstalling it at a new bay — and a lift in good mechanical shape survives that trip fine. The key is having someone who knows automotive two post lifts inspect the cylinders, cables, arms, and safety locks before money changes hands, not after.
Where used gets risky is with anything approaching that thirty-year mark, or any unit where you can’t verify how it was loaded. Posts can rot from the inside, cables stretch and fray in ways that aren’t visible until they fail, and older safety switches — the kind that stop working right and require a truck roll instead of a phone fix — are common failure points on aging equipment. If a seller can’t tell you the capacity, the brand, or show you a working safety lock, walk away regardless of price.
Capacity Planning for Restoration and Metal Work
Most restoration shops underestimate capacity needs because they’re thinking about curb weight, not the added weight of a lift loaded with tools, a body cart, or a partially reassembled frame hanging off one end. We generally steer restoration and heavy metal work customers toward 10,000 lb capacity as a floor, and often recommend 12,000 to 15,000 lb for shops that work on trucks, vintage trucks with heavy frames, or anything approaching three-quarter-ton and up. One customer looking to lift Hummers with GM adapters wanted a 15,000 lb two-post specifically because standard-capacity lifts and standard adapters don’t clear the wider frame — a good reminder that vehicle width and adapter reach matter as much as raw tonnage.
If your shop does a mix of daily driver work and long-term restoration projects, it’s worth having two different lifts rather than asking one unit to do both jobs. A lighter-duty lift for quick in-and-out repairs frees up your heavy-capacity two-post for the project that’s going to sit for weeks. That’s a pattern we see a lot in multi-generation shops that have grown their bay count over the decades rather than replacing one lift over and over.
Installation Logistics on the Iowa-Missouri Border
Whether you land on used or new, installation logistics look the same. We need to know if there’s a forklift on site, whether the bay has a pit or is a straight slab install, how far out concrete curing is, and what the ceiling height actually is — not what the building plans say it is. Rural shops along the border sometimes have older buildings with lower clearance or uneven floors from decades of settling, and that changes which automotive two post lifts will actually fit before we ever talk price.
We also ask about power. A 220V circuit needs to land within reach of the power unit, and if concrete is going in fresh, that’s the moment to get the location right — not after the pour, when you’re stuck running conduit along a wall instead of straight up through the floor. Lead time on new units varies by brand and season, so if you’re planning a bay renovation around a build deadline, get us the dimensions early.
Making the Call for a Family Shop
For a third-generation shop, the decision often comes down to what the next twenty years look like. If the plan is to keep doing heavy restoration and metal work indefinitely, we usually recommend new automotive two post lifts sized generously for capacity, with a warranty and a service relationship that will still make sense a decade from now. If the shop is smaller, budget is tight, and the work skews lighter, a carefully inspected used unit can carry a shop a long way — as long as somebody who knows what they’re looking at checks it first.
Either way, don’t guess on dimensions, don’t skip the cylinder and cable inspection on a used unit, and don’t assume old capacity ratings still apply after thirty years of service. We’d rather talk you out of a bad purchase than sell you equipment that doesn’t fit your bay or your work.
