Armed with Dodge Ram Heavy Duty’s superior suspension system, beefed up even more for commercial applications, Dodge Ram 4500 and 5500 Chassis Cabs provide expanded capability and durability with a commercial-grade chassis mated to a one-piece C-channel rear-frame rail (50,000 psi steel).

Two-wheel-drive and four-wheel-drive models feature a recirculating ball system that provides precise response and an on-center steering feel through lower internal friction. Improved power steering lines contribute to the delivery of precise feel and response for better handling. Featuring solid-beam front and rear axles, and a five-link, coil-spring front suspension with beam axle, a front and rear link-type sway bar and heavy-duty tubular shock absorbers are standard.

The rear suspension on two- and four-wheel-drive models is equipped with leaf springs and includes standard two-stage springs as part of the spring design for greater load-carrying capability.

Four cab-axle lengths (60, 84, 108 and 120 inches) are available. Maximum Gross Vehicle Weight Rating (GVWR) for 4500 models is 16,500. For 5500 models, the maximum GVWR is 19,500 lbs. The Gross Combined Weight Rating (GCWR) for both 4500 and 5500 models is 26,000 lbs.

The standard diesel exhaust brake system, together with class-leading brakes and pistons, provides extended brake life and increased driver control while contributing to enhanced safety performance. Standard four-wheel disc brakes with anti-lock braking system (ABS) ensure superior safety and crash-avoidance capability.

Unmatched Versatility and Upfit-Friendliness
Meeting all cab-axle and industry upfitter specifications, the 2008 Dodge Ram 4500 and 5500 Chassis Cabs bring unmatched versatility and upfit-friendliness with an enhanced commercial-grade, user-friendly chassis to the Class 4 and 5 chassis segments. Flat, “clean” frame rails with industry-standard 34-inch frame rail spacing provide versatility for virtually any upfit application. All chassis components are below the frame surface to facilitate after-market upfits or retrofits.
