Our Story

915 Industries was built on one principle: do the work right, find the root cause, and build things that last. Led by Robby Navarrete, this shop has earned its reputation in San Antonio through results — not marketing.

We handle everything in-house — from diesel and gas engine diagnostics to full engine builds, custom fabrication, performance tuning, and advanced CAD/3D scanning. When you bring your truck or project to us, it stays under one roof with one team accountable for the outcome.

Whether it's a full engine build, a custom roll cage, or reverse-engineering a part that doesn't exist anymore — we figure it out and we get it done.
