LET’S GET STARTED
Know the truck.
Understand the problem.
Do the work right.
A trouble code is a starting point. So is a horsepower goal. The important work is understanding what your truck needs—and why.
Zac started ZKB at 19 and has grown the shop over the years. Here, repair knowledge and performance knowledge belong in the same shop. We look at the whole combination, explain the next steps, and treat your truck like something you depend on.
Good work.

A few straight answers.
How do I schedule service?
Send an appointment request or call 816-548-0428. Tell us about your truck and the concern. We will follow up to discuss the work and confirm a time; a request does not reserve an appointment.
What happens during diagnostics?
We start with your symptoms and truck history, then use inspection, testing, and relevant operating data to narrow down the cause. We explain the findings and recommended next steps before you approve repairs.
How long will my truck be in the shop?
Timing depends on the concern, diagnostic findings, parts availability, and the work already scheduled. Contact us for a current estimate and tell us about any deadline before drop-off.
Can you help plan a performance build?
Yes. Share your current modifications, how you use the truck, power goals, budget, and timeline. We can discuss the combination, supporting systems, and a practical order of work.
Do you offer tuning support?
We offer emissions-compliant tuning support only. Required emissions equipment and controls stay functional. We do not offer emissions deletes, defeat devices, or calibrations that disable emissions monitoring.
Do I need an appointment for the dyno?
Please request a dyno appointment in advance. Tell us your drivetrain, tire setup, modifications, and testing goals so we can confirm compatibility and preparation.
Your truck. Our next project.
Let’s get it running right—or plan what comes next.
