Description
Challenger Lift A1078 Arm Pin Assembly for C10/CL-9/CL-10 2-Post Car Hoist
The Challenger Lift A1078 arm pin assembly is the connecting pin that secures the swing arm to the lift column carriage on CL-series 2-post lifts. The arm pin passes through the arm pivot point, allowing the swing arms to rotate outward for vehicle positioning while remaining firmly anchored to the carriage. Arm pins are subject to wear and corrosion from environmental exposure; a worn or corroded pin can introduce play in the arm pivot, affecting safe vehicle positioning. This assembly replaces the original A1078 and the later B1078 designation.

Fitment and Ordering Notes
Verify your specific lift model and serial number against the Challenger CL9 or CL10 parts diagram before ordering. Inspect the arm pivot bore and carriage holes for wear when replacing the pin – if the bore is elongated, additional components may need replacement. Replace arm pins in pairs on the same lift post for balanced wear.
