Extensions & Lift Arms

Replacement and extension lift arms for 2-post and 4-post vehicle lifts — standard swing arms, extended swing arms for longer-wheelbase vehicles, telescoping arm extensions, and complete arm assemblies for Challenger, Atlas, and APlusLift lift platforms. Arm condition is critical to safe lift operation and ALI certification compliance. This collection covers OEM and direct-fit replacement arms. Alamo Equipment is an authorized dealer with parts availability and technical support nationwide.

Extensions & Lift Arms FAQs

Lift arms are the load-critical interface between lift and vehicle —replace at the first sign of damage to maintain safe operation and certification.

Replace immediately at any sign of bending, cracking at welds, worn or deformed adaptor pad receivers, sloppy pin fitment in the carriage, or visible structural damage. Lift arms are load-critical components — there is no acceptable repair, only replacement. Visual inspection should be part of every daily lift use check.

No. Carriage pin diameters, mounting geometry, and locking mechanisms vary by manufacturer. Atlas arms do not fit Challenger carriages and vice versa. Order arms matched to the exact lift make and model, and verify with the parts desk before installing.

Standard arms cover most passenger car and light truck applications. Extended arms add several inches of reach for longer-wheelbase vehicles — full-size pickups, full-size SUVs, and some crew cab applications — where the standard arm cannot reach the proper lifting points. Extended arms typically reduce the effective lift capacity slightly due to longer load moment.

Telescoping extensions slide out from the end of a standard swing arm, providing variable reach for mixed-fleet operations. They allow the same arm to handle short passenger cars and longer trucks without changing arms. Common on mid-range and premium 2-post lifts.

ALI certification applies to specific model and configuration combinations. Replacing arms with OEM parts of the same specification maintains certification. Substituting non-OEM or different-rated arms can void ALI Gold Label status. Document arm replacements with OEM part numbers for compliance audits.

Often yes, slightly. Extended arms increase the load moment arm at the carriage and column. Manufacturers typically derate capacity by 5 to 15 percent when extended-reach configurations are used at maximum extension. Check the specific arm's load chart before lifting heavy vehicles.

The cup or pad-mounting feature at the end of each arm holds the lifting pad against the vehicle. Pad receivers wear from repeated pad insertion and removal, vehicle settling movement during service, and pad rotation during arm positioning. Replace arms when receivers are worn enough that pads will not stay securely seated.

Common arm sets for current Atlas, Challenger, APlusLift, and Stratus lifts typically ship within 1 to 5 business days. Older or specialty arm configurations may require 1 to 3 weeks from the manufacturer. Contact the parts desk with the exact lift model and serial for current availability.
