Fitment & Ordering Notes
Challenger Lift components can vary by model, serial-number range, production date, lift height, side or orientation, color, power-unit configuration, and equipment revision. Before ordering, compare the manufacturer part number, specifications, diagram callout, model information, and original component. A similar appearance alone does not confirm interchangeability.
