Custom Fab – Custom Fabrication for Semi-Trucks & Trailers

When off-the-shelf just won’t cut it, Custom Fab steps in.

In the trucking and trailer industry, Custom Fab – short for Custom Fabrication – means creating specialized parts, components, or structural modifications built from raw materials to suit specific jobs, loads, or operator preferences. At STTR, we turn your vision into real-world solutions that perform under pressure.

1. Tailored Solutions for Your Unique Needs

No two jobs are the same, and your truck shouldn’t be either. Custom fabrication gives you the freedom to adapt your vehicle to exact requirements – whether you’re hauling oversized equipment, operating in unique environments, or need a mobile setup tailored to your trade. We work directly with you to design, fabricate, and install one-of-a-kind solutions that standard parts just can’t match.

2. Enhanced Functionality & Performance

We don’t just modify trucks – we optimize them.
Whether it’s adding a custom flatbed, hydraulic ramps, specialized hitches, or living quarters inside a trailer, our fabrication team can enhance your vehicle’s functionality and safety. Popular upgrades include:

• Installation of Reinforced truck bodies

• High-performance exhaust systems

• Custom hitches or towing packages

• Utility racks and secure tool storage

• Suspension upgrades for better handling and load stability

3. Built to Last: Quality & Durability

Custom Fab isn’t just about how it looks – it’s about how it holds up.
Every piece we fabricate is built using high-grade materials and industry-tested construction methods. Our custom builds are designed to handle extreme use, tough environments, and long hauls without compromise. You get stronger parts, better fitment, and lasting performance.

4. Design Flexibility & Real-World Problem Solving

Space constraints? Compatibility challenges? Specialty cargo? We’ve seen it all.
Custom fabrication allows our team to develop solutions that fit within tight tolerances, match existing systems, or overcome physical limitations. Whether you’re modifying a trailer for a unique piece of equipment or retrofitting a truck with hard-to-find parts, we make it happen.

Examples of Custom Fabrication We Offer:

• Frame Stretching: Extend your truck’s frame to carry longer loads or add accessories.

• Cheater Axles (Drop Axles): Add auxiliary axles to increase load capacity and improve balance.

• Installation of Dump Beds: Fabricate and install hydraulic or specialized beds for hauling materials.

• Custom Ramps, Doors & Windows: Modify trailers to accommodate specific types of cargo or on-site service access.

• Installation of Custom Truck Bodies: Purpose-built truck bodies tailored for trade professionals, freight, towing, or unique commercial applications.
