About STI Service Bodies
Service Truck International designs its service bodies with a focus on field-ready performance. STI bodies are built from heavy-gauge steel with a durable powder-coat finish, and the compartment layouts are engineered around actual tradesman workflows — not just box storage. Every compartment has positive-latch doors, reinforced hinges, and drain holes to keep water and debris out of your tools.
STI offers multiple service body series at Star Truck Equipment:
- STI Standard Service Body — Side and rear compartments, available 8’–11′ body lengths, for F-250 through F-550 platforms
- STI Mechanics Truck Body — Expanded compartment layout with internal crane-ready reinforcement, compressor mounting provisions, and optional top boxes
- STI Lube Body — Specialized for fluid management and preventive maintenance trucks; includes tank provisions and reel compartments
- STI Fuel/Lube Combo — For oilfield service trucks that handle multiple fluid types in a single unit

STI vs. Other Service Body Brands
STI competes directly with Knapheide, Maintainer, and NAP (National Alloy Products) in the service body market. STI’s strength is its systems integration — the bodies are designed around the truck platform, not just to a generic spec. For buyers comparing options, we have detailed comparisons on our blog:
