Challenger CL10 2-Post Lift: Real Install and Buying Guide

The Challenger CL10 is the two-post lift we install the most in Iowa. Ten-thousand-pound capacity, switchable symmetric or asymmetric arm configuration, and column extension options from 2 feet up to 6 feet for higher-ceiling shops. We are Auto Lift Services in Ames, and last year we installed CL10 lifts in Iowa City, Knoxville, Des Moines, Cedar Rapids, and a handful of small towns in between. This piece walks through what the lift is, a recent install we did, and what to expect if you buy one from us.

The Challenger CL10 in Plain Language

Two columns. Asymmetric or symmetric arm swing. Ten thousand pound total capacity. Standard column height around 12 feet, with taller extensions available. Cable equalization between the carriages, hydraulic power unit on one column, top-of-column ceiling shutoff. That is the whole design in one paragraph.

What makes the Challenger CL10 different from a cheaper 10K lift is the arm restraint mechanism, the ALI Gold Label certification, and the parts network behind it. When something wears out five years in, the replacement is a phone call, not a treasure hunt. That matters more than any spec sheet difference. We have shops calling us in year 10 or 12 asking for the exact same cable set they got the first time — and we still stock it.

A Recent Install in Central Iowa

We recently installed three CL10 lifts in one day at a tire and auto shop in a small town south of Des Moines. The bay was already sized for lifts — this was a replacement job for an aging fleet of three older two-posts. We got in at 7 AM, had the old lifts out by 10, had the anchors drilled and columns up by 2 PM, and the crew ran a vehicle up on all three by end of day.

The reason the job ran that fast was prep. The shop had the electrical already landed, the ceiling was clear, the floor had been cleaned and marked. If you can do that on your end, our crew can move fast on ours. Read our 2-post install piece for the prep checklist we send you before we come out.

Column Height and Extensions

Standard column is about 12 feet 2 inches tall. That fits under most commercial 14-foot ceilings with headroom to lift the average car or half-ton pickup all the way up. If you have a taller ceiling — 16 feet or better — you can order the CL10 with 2-foot, 4-foot, or 6-foot column extensions. Extensions raise the working height, which lets you lift lifted trucks, cargo vans, and tall SUVs to a comfortable working position.

The trade-off with extensions is ceiling headroom over the top of the vehicle. If you extend the columns to their tallest configuration and then try to lift a Sprinter van under an 18-foot ceiling, you can still hit the ceiling because the shutoff switch is limited by the column extension. Do the math before you order. We check it for you at the quote.

Concrete and Anchor Basics

The Challenger CL10 needs 4 inches of concrete at 3,000 PSI, and Challenger publishes anchor torque specs that we follow. If your floor is a residential slab, a pole-barn thin pour, or heavily cracked, we tell you before we come out. In borderline cases we can drill deeper anchors or cut a pit and pour anchor pads.

Never install a 2-post on asphalt, on concrete over dirt fill that has not been engineered, or on a floor thinner than 4 inches. This is the number one shortcut that leads to failure. We have gone out on service calls where a lift was tipping because the anchors pulled up, and every time it traces back to the floor. The lift is only as safe as what you bolt it to.

What You’ll Actually Do on a CL10

Brake jobs, tire rotations, oil changes, exhaust work, transmission service, coolant flushes, ball joints, tie rods, wheel bearings, u-joints, differentials. The CL10 handles the full range of underbody service on cars and light trucks. With the asymmetric arm setting, the doors clear the columns on most sedans and coupes — you can open the driver’s door without hitting the column.

What you cannot do on the CL10 is lift a fully loaded 3/4-ton dually with a slide-in camper. That is over the 10K capacity. If half your work is heavy pickups or work trucks, step up to the CL12A. Our CL12A article covers when the 12K capacity is worth the extra money.

Cables, Locks, and Parts

The CL10 uses lifting cables to equalize between the two carriages. Cables are the primary wear item. Under normal shop use they last 8 to 12 years depending on cycles, humidity, and how the lift is maintained. When they get replaced, we do both sides at once — you never do one cable on a 2-post lift.

Safety lock ladders, arm restraint gears, sheaves, and hydraulic seal kits are the other parts we stock for this lift. All of it ships same-day from our Ames warehouse to shops across Iowa and the Midwest. If your CL10 is 10 years old and the cables are due, call 800-674-9302 and we can quote cable replacement labor plus parts on one line.

Getting Yours On Order

Ordering is short. Call, tell us your city and bay layout, pick pickup or installed, put down a deposit, and we schedule you. Freight time from Challenger to us is generally two to three weeks; our install schedule usually opens within another week or two. Total time from order to lifted vehicle is often under a month.
