Challenger 18K 4-Post Alignment Rack Package #AR44018AR

Challenger 18K 4-Post Alignment Rack Package #AR44018AR

Alignment work on a general-service 4-post means bolting turn plates on, taking them off, and hoping nothing shifted — every single job. The AR44018AR removes that handling: an 18,000 lb four-post alignment rack package with dual turn plate cutouts and dual built-in rear slip plates, so the rack is always alignment-ready.

With 17 level lock heights, a 236 in. maximum wheelbase, and 4-wheel alignment capability spanning 98" - 206", the package configuration covers 4-wheel alignment work on long-wheelbase trucks and vans without bolt-on turn plate handling.

Who the AR44018AR Is Built For

• Shops adding or expanding alignment work — the built-in turn plate cutouts and rear slip plates make the rack permanently alignment-ready.
• Alignment bays serving long-wheelbase trucks and vans within the 236 in. maximum wheelbase and 18,000 lbs rating.
• Shops that need repeatable working heights — 17 level lock heights let the tech set the rack where the aligner wants it.
• Buyers who want the single-point air-actuated lock release (alignment model) instead of walking between columns.
• Teams comparing the alignment package against the general-service 44018E.

What the AR44018AR Is NOT Built For

This is not the right choice when your vehicle weights exceed 18,000 lbs, your wheelbase exceeds 236 in., or your bay cannot absorb the 311.5 in. footprint. If you are close on any spec, compare it with Challenger 18K 4-Post General Service Lift #44018E or call Alamo.

Important sizing note: The AR44018AR publishes 18,000 lbs capacity, 311.5 in. overall length, and 141.5 in. overall width with 4-wheel alignment capability from 98" to 206". Measure the bay and confirm the exact vehicle mix before purchase.

What Makes the AR44018AR Different

Built-In Alignment Package

The dual turn plate cutouts and dual built-in rear slip plates are the whole point of the AR configuration: plates are mounted in the rack, not bolted on per job. 4-wheel alignment spans 98" - 206" with a 220" maximum 2-wheel alignment span — so long-wheelbase trucks align without adapters or improvisation.

• Confirm your aligner works with the rack's plate positions before ordering.
• Match your vehicle mix against the 236 in. maximum wheelbase.
• Ask Alamo to compare the 44018E if alignment work is not on the roadmap.
• Keep the install team involved before the bay is committed.

17 Level Lock Heights

Seventeen level lock heights mean the rack locks at the height the aligner and the tech prefer — not at the three heights a standard service lift happens to offer. That repeatability is what keeps alignment readings consistent between techs.

Single-Point Air-Actuated Lock Release

The alignment model releases both column locks simultaneously from one air-actuated control — Challenger lists the air-actuated single-point release specifically on the alignment model, which keeps alignment-cycle turnaround fast.

Bay Planning Numbers

The key measurements are the 311.5" x 141.5" footprint, the 102.5" overall height plus the raised vehicle, and the 236" maximum wheelbase. Alignment bays also want a level floor and clear aligner sight-lines — check those before the rack is ordered.

Capacity and Vehicle Mix

The 18,000 lbs rating is the hard ceiling for the rack, not a target to exceed. If your alignment mix runs loaded medium-duty trucks at or near the rating, call Alamo before ordering so we can confirm the safer match.

Service After the Sale

Alamo installs and services the lifts we sell, so the same team that helps size the AR44018AR can support the rack after it is in the bay.

Best For

• Shops adding 4-wheel alignment on trucks and vans
• Alignment bays within the 236 in. maximum wheelbase
• Techs who need repeatable working heights (17 lock levels)
• Buyers who want Alamo installation and service support

Not Ideal For

• Wheelbases beyond the 236 in. maximum
• Vehicles above the rated capacity
• Bays too short for the 311.5 in. footprint
• Shops that only need general service, not alignment

Warranty terms can change. Confirm exact coverage at the time of purchase. Warranty can be void if the lift is installed improperly or not anchored per spec.
