Challenger 15K 4-Post / Alignment #AR4115EAO

Challenger 15,000 lb 4-Post Alignment Lift — Open Front, Alignment-Ready

A shop that wants to add dedicated wheel alignment as a service line often runs the numbers on a base 4-post lift, then finds out the turnplates, slip plates, and rolling jacks needed for real alignment work are a separate line-item purchase — and now they're coordinating two orders, two delivery windows, and hoping everything is compatible when it arrives.

The Challenger AR4115EAO is the Alignment-Ready configuration of the 15,000 lb 4-post platform — stainless steel turn plates, slip plates, rolling jacks, and an internal airline system all ship standard, so the lift is ready for 4-wheel alignment work the day it's installed. No separate alignment-kit purchase, no compatibility guesswork.

Who the AR4115EAO Is Built For

• A shop adding dedicated wheel alignment as a new service line and wanting the turnplates, slip plates, and rolling jacks included standard instead of sourced and ordered separately.
• A tire or alignment center running high daily alignment volume where the internal airline system keeps rolling jacks connected and ready without dragging separate air hoses across the bay floor.
• A dealership service department that needs alignment-ready capacity out of the box to hit service-department SLA windows without waiting on a second equipment order.
• A shop with a deep bay (14' x 26' minimum) that wants the full alignment package in the standard-length footprint rather than the extended XAO/XAX variants.
• An operation replacing a worn-out standalone alignment lift and consolidating rolling jacks, turnplates, and slip plates into one integrated 15,000 lb platform.
• A fleet or commercial shop in a high-humidity or road-salt climate considering the optional galvanized coating to protect the alignment hardware and runways from corrosion over years of daily use.

What the AR4115EAO Is NOT Built For

If your shop doesn't run dedicated 4-wheel alignments and mostly needs general service and suspension capacity, the base 4115EFO covers the same 15,000 lb capacity without paying for alignment hardware you won't use. And if you need the alignment kit in a longer-wheelbase footprint, the AR4115XAO extends to a 210.5" max wheelbase.

What Makes the AR4115EAO Different

Galvanized Coating Upgrade Available

An alignment-dedicated lift running high daily volume puts steady wear on runways, jack rails, turn plate pockets, and slip plate pockets. The optional galvanized coating protects those contact points from corrosion in coastal, humid, or road-salt regions, which matters more on a lift that's running turnplates and slip plates constantly rather than occasionally. Ask Alamo about it before ordering if your shop sees harsh winters or heavy moisture.

All-New 22" Wide Runways

The AR4115EAO's 22.375" runways give techs more stable footing while working around the integrated turnplates and slip plates during an alignment, and give a wider variety of vehicles more surface to land on during loading. That matters on a lift that's cycling through vehicles all day for dedicated alignment work.

Open and Closed Front Configurations

This configuration keeps the alignment-ready hardware paired with an open-access front, so techs aren't reaching around a column brace while setting turnplates or adjusting slip plates mid-alignment. If structural rigidity matters more for your heavier-vehicle mix, the AR4115EAX pairs the same alignment kit with a closed front.

Improved 4-Wheel Alignment Wheelbase

The 4115 platform's extended wheelbase range means the AR4115EAO handles a wider span of vehicle sizes on the same integrated alignment hardware, without swapping to different equipment mid-shift. For a shop running high alignment volume across a mixed customer base, that's fewer interruptions to the day.

Louvered Approach Ramps

On a lift doing dedicated alignment work all day, approach ramps see constant traffic. Louvered ramps hold their grip better over time than diamond tread or abrasive strip designs, which keeps wheel spin down and vehicle loading confident even after years of heavy daily use.

• Alignment Kit Included: Rolling jacks, internal airline system, and stainless steel turn plates included — ready for wheel alignment work out of the box
