Frequently Asked Questions

Get quick answers about our services and builds. If you don’t see what you’re looking for, reach out and we’re happy to help.

  • What types of trucks do you work on?

    We work on all major diesel platforms including Cummins, Duramax, and Powerstroke. From daily drivers to fully built performance trucks, we handle a wide range of setups and applications.

  • Do I need an appointment or can I stop by?

    We recommend scheduling an appointment so we can dedicate time to your truck and go over your goals. You’re welcome to stop by, but calling ahead helps us get you taken care of faster.

  • Do you offer financing options?

    Yes. We offer multiple financing options for qualifying repairs, upgrades, and performance builds, including Affirm, Synchrony Car Care, Snap Finance, and Sunbit. Some options can be applied for online before your visit, while others are available directly in-shop with fast approval decisions. Visit the financing section to compare options and find the best fit for your project.

  • Can you help plan my build, or do I need to know exactly what I want?

    We’ll guide you through the process. Whether you have a clear plan or just an idea, we’ll help you choose the right setup based on your goals, budget, and how you use your truck.

  • How long does a typical repair or build take?

    It depends on the scope of the work. Routine services can be completed quickly, while larger builds or fabrication projects take more time. We’ll give you a realistic timeline upfront.

  • Do you offer custom tuning for my setup?

    Yes. We provide custom tuning tailored to your specific truck and modifications to ensure proper performance, drivability, and reliability.

  • Do you work on performance and race trucks?

    Yes. We have tons of experience building and supporting trucks for racing, as well as high-performance street setups. Our work is backed by real-world testing and track experience.

  • Can you diagnose issues if another shop already worked on my truck?

    Yes. We regularly work on trucks that have had previous work done elsewhere. We’ll evaluate the setup, identify any issues, and recommend the best path forward.

  • Do you handle fabrication in-house?

    Yes. All fabrication is done in-house, allowing us to control quality, fitment, and overall execution on every build.

  • Do you provide quotes before starting work?

    Yes. We’ll review your request and provide a clear breakdown of the work before getting started.

  • Do you work with out-of-town customers?

    Yes. We work with customers across Texas and beyond. If you’re traveling, we can coordinate timing and scheduling in advance.

  • What should I include when submitting the contact form?

    The more detail the better. Include your truck, current modifications, any issues, and what you’re looking to accomplish so we can provide accurate recommendations.
