Policy
Emissions & tuning
Draft policy pending review. Last updated September 2026.
Our approach
We build trucks to perform and to stay on the road. Where a manufacturer offers an emissions-compliant version of a part or calibration, that is what we recommend for street-driven trucks.
Product labeling
Every part and tune we sell carries its manufacturer’s emissions status. Some products are labeled for off-highway or competition use only and are not intended for vehicles driven on public roads. We will tell you which is which before you buy.
Before we start work
For any job that touches emissions-related systems, we review the work with you and ask you to sign an acknowledgement describing the parts, calibration and intended use. You get a copy in your customer portal.
Your responsibility
Federal and state law regulate changes to vehicle emissions systems. Owners are responsible for how their vehicle is used and for keeping it compliant where they drive it.
Questions
Call or text (843) 995-9252 or email service@luckydiesel.com before you buy. We’d rather answer a question than sell the wrong part.
