About us

Why we started SureNOX?

We started with a simple frustration: seeing fleet managers and truck owners paying unreasonably high prices for NOx sensors that are often outsourced to the same manufacturers in China. The big OE brands just slap their label on the product and inflate the price. On the other hand, we've also seen too many cheap, low-quality sensors that don’t last, causing frequent replacements and costly downtime for truck owners. There must be a better way! That’s why we cut out the middlemen and deliver the same high-quality NOx sensors, built to last, directly to you—saving you both time and money. Our mission is to help you drive further, spend less, and keep your trucks on the road without hassle.
