2026 Chevrolet Express Chassis 4500

This is Chevrolet's bare-bones work chassis, the platform behind box trucks, tow trucks, and cutaway vans. It's built to haul heavy loads all day, with a firm ride and steering that feels truck-like rather than car-like. The cabin is utilitarian with hard plastics and basic controls, but you get a solid work truck that's easy to upfit. The Express has a long-standing reputation for durability in commercial use, though it's a dated design compared to newer rivals. The 4500 is the heavy-duty chassis in the Express lineup, sitting above the 3500 with a higher gross vehicle weight rating for bigger upfits. It uses a 6.6L I8 with an automatic transmission and rear-wheel drive, giving you steady torque for hauling heavy loads all day.
