2025 Chevy Silverado 5500HD Truck Body Options

The 2025 Chevrolet Silverado 5500HD is a medium-duty cab-and-chassis truck designed for serious commercial upfitting. With a GVWR of up to 19,500 lbs, available Duramax 6.6L diesel, and a robust chassis frame, the Silverado 5500HD handles flatbeds, service bodies, crane bodies, and mechanics trucks with ease. Star Truck Equipment in Wharton, TX specializes in upfitting Silverado 5500HD trucks for contractors, utilities, oilfield operators, and fleet buyers across Texas and Louisiana.

2025 Silverado 5500HD Cab-to-Axle (CA) Measurements

The Chevy Silverado 5500HD is available in Regular Cab and Crew Cab configurations with the following CA options:

Regular Cab: 60″ CA or 84″ CA or 108″ CA
Crew Cab: 60″ CA or 84″ CA

The 84″ CA is the most popular for 9′ service bodies and 9’4″ flatbeds. The 108″ CA (Regular Cab only) is used for extended service bodies, lube trucks, fuel trucks, and mechanics trucks where extra compartment depth is needed. Always confirm your CA before ordering a body.

5500HD vs 4500HD: Which Silverado for Upfitting?

The Silverado 5500HD offers a higher GVWR (up to 19,500 lbs) compared to the 4500HD (up to 14,500 lbs). If you’re running a full crane body build, a heavy mechanics truck, or a lube/fuel service truck, the 5500HD’s extra capacity is the right choice. For lighter service body applications, the 4500HD is sufficient and often more economical.

Flatbed Options for the Silverado 5500HD

The Silverado 5500HD is always DRW at the 5500 class, giving you a wide stance for stable flatbed work. Popular options from our lineup:

Bedrock Granite 9G — 9’4″ x 94″ DRW flatbed with 25,000 lb gooseneck coupler. One of the most popular flatbeds for the Silverado 5500HD. Heavy-duty 2″x6″ frame handles the platform’s full payload.
CM RD or CM SK — 9’4″ wide-body flatbeds in welded steel. The SK variant adds livestock/ranch-friendly rail options popular on Texas farms.
Norstar SD (94″) — Built heavy for the Texas work environment. Excellent for ranch, contractor, and oilfield use on the 5500HD platform.
Bradford Built — Premium flatbeds in powder-coat finish. Available in multiple widths and configurations for the 5500HD.

Service Bodies for the Silverado 5500HD

The 5500HD’s higher GVWR makes it ideal for heavy-duty service bodies and combo (service body + crane) builds. You have significantly more payload available compared to the one-ton pickups, meaning you can spec a full-size service body, load it with tools and parts, and still have room for a service crane:

RKI Service Bodies (Houston, TX) — Contractor, combo, and crane-ready service bodies. RKI’s steel and aluminum bodies fit the 5500HD perfectly on 84″ CA chassis.
STI Service Bodies — STI’s heavy-duty service bodies, mechanics trucks, and lube/fuel bodies are a natural match for the 5500HD’s capacity. The 108″ CA Regular Cab 5500HD with an STI lube or fuel service body is a popular configuration for Texas oilfield operators.
CM Service Bodies — Available in standard and premium configurations for medium-duty applications.

Crane Body Options for the Silverado 5500HD

The Silverado 5500HD is one of the most popular base vehicles for crane body builds in Texas and Louisiana. The 19,500 lb GVWR gives you room for a heavy crane body plus crane weight without exceeding limits. Common configurations:

9′ crane body (RKI or STI) + Tiger service crane (3,000–6,000 lb capacity)
Extended service body (108″ CA) with liftable rear section and crane
Mechanics truck body with integrated crane pedestal
