Mileage Blocker for Diesel Trucks — The Complete Guide
Diesel truck owners are some of the most serious vehicle enthusiasts on the road. Whether you’re tuning a 6.7L Power Stroke, running a Cummins on the dyno, or testing your Duramax after a build, the last thing you want is unnecessary mileage adding up during your testing sessions.
Our diesel truck mileage blockers are specifically designed for the complex CAN Bus systems found in modern heavy-duty trucks — ensuring complete, undetectable odometer stopping across all ECU modules simultaneously.

Why Diesel Trucks Need a Proper CAN Bus Mileage Blocker
Modern diesel trucks are some of the most electronically complex vehicles on the road. The Power Stroke, Cummins, and Duramax platforms all use sophisticated CAN Bus networks that communicate mileage data across multiple modules. A cheap plug-in device won’t cut it — only a properly engineered CAN Bus filter can intercept the signal across all modules simultaneously.
Perfect for Dyno Testing Diesel Engines
Diesel tuning shops frequently use our mileage blockers when putting customer trucks on the dyno. A typical dyno session can add 20–50 miles of odometer reading for what is effectively a stationary test. Our blocker prevents this entirely — keeping the customer’s mileage clean.
