If you’re a weekend mechanic in Ankeny shopping for automotive two post lifts for the first time, the arm style question trips up almost everyone. We get calls all the time from guys with a pole barn or a third stall who found a lift online, watched a few videos, and then realized there are two totally different swing-arm designs and nobody explained the difference before they clicked buy. We install these across central Iowa every week, and the arm geometry decision matters just as much as tonnage or brand. Before you spend money on automotive two post lifts, walk through this checklist with us so you don’t end up fighting your own equipment every time you pull a car in.
See symmetric and asymmetric two post lifts we stock and install throughout the Ankeny and greater Des Moines area, with freight and setup handled by our crew.
Symmetric vs Asymmetric: What Actually Changes in Your Garage
Symmetric arms sit centered on the columns, so the car goes straight up the middle and the door swing is even on both sides. That’s great if you’re mostly doing oil changes, brake jobs, and general maintenance on a mix of vehicles, because you don’t have to think about positioning every time. Asymmetric arms shift the front columns back and rotate the whole car slightly, opening up extra room to get in and out of the driver’s door and giving you a bit more clearance for hood work near the front columns.
For a home garage doing general daily maintenance work, we usually steer weekend hobbyists toward symmetric unless you’re specifically working on longer trucks or SUVs where the door clearance matters. Asymmetric setups are more common in production shops doing alignment and quick-turn service. Either way, once you own it, the geometry is fixed, so this isn’t something you fix later with a different swing-arm kit. Get it right before the lift ships, not after it’s bolted to your slab.
Ceiling Height and Bay Width Before You Buy Automotive Two Post Lifts
We ask every Ankeny caller the same first questions: what’s your ceiling height, and how wide is the bay. A typical two post lift needs roughly 10 to 12 feet of clearance depending on the model and the vehicle you’re lifting, and asymmetric arms can change your usable footprint since the car sits at an angle rather than straight ahead. If you’ve got a pole barn with 10-foot trusses, that limits which automotive two post lifts will actually clear your rafters with a full-size truck on the arms.
Bay width matters just as much. You need enough room on both sides for the columns plus swing clearance for arms and doors, especially with asymmetric geometry where the front end kicks out further. We’ve had customers measure the concrete pad but forget to check for overhead garage door tracks, HVAC ductwork, or a low header right where the lift needs to sit. Bring us your ceiling height, floor dimensions, and a photo of the bay before you order, and we’ll tell you honestly whether a two-post fits or if you’re better served by a mid-rise or four-post for that space.
Concrete Readiness: The Detail That Kills Installs
We can’t stress this enough: your slab has to be right before we show up. We ask about concrete thickness, whether there’s rebar, whether the floor has in-floor heat, and whether it’s new pour or existing. A thin or cracked slab under 4 inches often can’t hold anchor bolts for a 10,000 lb or heavier two post lift, and in-floor heat lines mean we have to map anchor points carefully so we don’t drill into a heat loop.
If you’re pouring new concrete specifically for this project, tell your concrete guy up front what’s going on top of it. We’ve seen homeowners pour a beautiful floor, then call us only to find out it’s too thin for the anchor depth the lift manufacturer requires. Get us involved before the pour if you can, or at minimum send us the slab specs before you commit to a lift. This single step prevents more install delays than anything else we run into with home and small-shop customers.
Symmetric Arms and Daily Maintenance Habits
For the weekend mechanic doing oil changes, brake work, exhaust jobs, and general upkeep, symmetric two post lifts tend to fit the rhythm of that work better. You pull straight in, the arms reach evenly, and you’re not repositioning the vehicle to account for an offset lift point. There’s less to think about, which matters when you’re squeezing wrench time into evenings and Saturdays.
The tradeoff is door clearance. On a symmetric lift, opening a full-size truck door next to the column can be tight. If your daily maintenance routine involves a lot of getting in and out of the cab, some hobbyists find that annoying enough to prefer asymmetric anyway. We tell people to sit in their own vehicle next to a similar lift at a shop if they can, before deciding. It’s a small thing that becomes a daily annoyance if you guess wrong.
What Warranty and Repair Support Should Look Like
Whatever brand you land on, ask what the warranty package actually covers before you sign anything. Some coverage plans include equalizer cables, hydraulic hoses, cylinders, and rubber pad inserts, and some stock those exact parts so they can ship within 24 hours of a call. That matters because a cable or cylinder failure means your lift is stuck down or stuck up until the part arrives, and for a weekend hobbyist that could blow an entire Saturday project.
Arms, structural components, and conversion kits are sometimes excluded from the fastest-tier coverage, so read the fine print rather than assuming everything’s included. We also get calls from owners of older, used two post lifts who had a valve fail and the lift dropped unexpectedly while unattended — a real reminder that hydraulic components age out even on a lift that looks fine. Ask about cylinder rebuild and valve service availability before you buy, not after something drops.
New vs Used: What We See Go Wrong
Buying a used two-post off a classifieds listing can save money, but we see the downside often. Unknown maintenance history, missing manuals, mismatched or substituted parts, and safety mechanisms that were removed or bypassed are common. One caller told us he’d removed the safety stops on an older Rotary two post, stepped away, and came back to the lift having dropped several feet on its own — a serious hazard that could have caused real damage or injury.
If you’re buying used, budget for us to inspect cables, hoses, cylinders, and the locking mechanism before you trust it with a vehicle underneath. New automotive two post lifts from Rotary or BendPak come with documented specs, current safety mechanisms, and a manufacturer warranty that used equipment simply can’t match. For a home garage where you’ll be underneath the car by yourself, that peace of mind is worth factoring into your budget.
Getting a Straight Quote for Ankeny and Central Iowa
When you’re ready to actually price this out, we need a few specifics: is this personal use in a home garage or pole barn, what’s your ceiling height, is there a pit, do you have a forklift on site for delivery, and what’s your timeline. Freight and lead time on two post lifts can vary quite a bit depending on the model and manufacturer backlog, so we’ll give you a realistic install window rather than a guess.
We serve Ankeny along with Ames, Des Moines, and the rest of central Iowa, and we handle everything from the quote through delivery, anchoring, and startup. If you’re still torn between symmetric and asymmetric arms for your specific bay and vehicles, call us and walk through it with our team before you order. It’s a lot cheaper to ask the question now than to own automotive two post lifts that fight your garage every single day.
