When Texas and Louisiana contractors start shopping for a steel service body, two names come up regularly: Norstar SB and RKI (Rawson-Koenig Industries). Both are solid, American-made options built for hard work — but they suit different buyers and different applications. This guide breaks down the real differences so you can make the right call for your rig.
Norstar SB Service Body: Built for Workhorse Simplicity
The Norstar SB is Norstar’s flagship steel service body — a no-nonsense workhorse designed for tradespeople, ranchers, and contractors who need reliable storage and organization without overcomplicating things. Norstar builds a clean, well-finished unit that holds up to daily abuse in the Texas heat.
Norstar SB Highlights
- Heavy-gauge steel construction — durable powder-coat finish that resists rust and corrosion
- Multiple compartment configurations — choose the layout that fits your trade
- Standard gull-wing doors — easy access from either side
- Built-in weather seals on compartment doors
- Available in 8′, 9′, and 10′ lengths to match common cab-to-axle measurements
- Competitive price point — one of the best value steel service bodies on the market
The Norstar SB is a great fit for plumbers, electricians, HVAC technicians, and general contractors who want clean storage access and a proven build without paying for premium extras they don’t need. Browse Norstar service bodies at Star Truck Equipment.
RKI Service Body: Engineered for Demanding Trades
RKI, made right here in Houston, TX, takes a slightly heavier-duty approach to the steel service body segment. RKI has built a reputation for robust construction, refined compartment geometry, and fit-and-finish that competes with premium brands — but at a reasonable price for what you get.
RKI Service Body Highlights
- Heavier-gauge steel on critical structural areas — handles heavier tool loads
- Superior door geometry — compartment doors open wide and stay out of the way
- Multiple top-opening compartment options — great for long tools and pipe storage
- Quality powder-coat finish — applied over a thorough prep process for long-term corrosion resistance
- Modular accessory options — pipe racks, ladder racks, crane-ready configurations
- Made in Houston, TX — strong local dealer and service support across Texas and Louisiana
RKI is the preferred choice for oilfield service, heavy electrical contractors, pipeline crews, and fleet managers who run high-mileage, high-demand trucks. Explore RKI service body options at Star Truck Equipment.

Which Service Body Should You Buy?
Choose the Norstar SB if: You want a dependable, clean steel service body at a competitive price. You run a trade truck (plumbing, electrical, HVAC, landscaping) and need solid organization and access. You’re buying your first service body or outfitting a small fleet on a budget.
Choose RKI if: You work in oilfield, heavy construction, or pipeline service where the truck takes serious abuse. You need crane-ready configurations, top-opening compartments for long materials, or a body that can handle overloaded days without complaint. You’re building a long-haul fleet truck and want the extra durability margin.
Compatible Trucks
Both the Norstar SB and RKI service bodies are available for the most common work truck platforms used across Texas and Louisiana:
- Ford F-350 and F-450 — most popular platform for steel service bodies
- Ram 3500 and 4500 — excellent torque for heavier body configs
- Chevy Silverado 3500HD and 4500HD
- GMC Sierra 3500HD
Service bodies pair best with crew cab or extended cab cab-chassis trucks in DRW (dual rear wheel) configuration for maximum payload stability. Our team will help you match the right cab-to-axle measurement for a clean, legal install.
