Heavy-Duty Chassis for Long Wheelbase Cars and Convertibles
When strength, ride quality, and handling matter, Art Morrison Enterprises delivers. Our heavy-duty chassis are specifically engineered for long wheelbase cars and convertibles, utilizing massive 4″ x 4″ x .180″ wall main rails to provide the rigidity these vehicles demand.
Convertibles lack the structural support of a fixed roof, making chassis strength critical to ride quality and handling. Long wheelbase vehicles face similar challenges, as increased frame length can contribute to torsional flex and reduced responsiveness. AME’s heavy-duty chassis are designed to minimize flex, improve stability, and create a solid foundation for modern performance.
Each chassis features heavy-duty 4″ x 4″ main rails that transition into mandrel-bent 2″ x 4″ frame rails for maximum strength, consistency, and appearance. Every chassis is precision fixture-welded and custom engineered for your exact year, make, and model, ensuring proper suspension geometry and fitment.
Integrated through-frame exhaust passages allow the exhaust system to be routed within the chassis for exceptional ground clearance and a clean installation. Steering is handled by AME’s proven 17.5:1 power rack-and-pinion system, delivering precise control and modern steering feel.
