About

Built in the bay, sold to the street.

Diesels R Us is a small performance shop based in Houston, TX. We're run by working diesel technicians — not marketers, not resellers. Every part we sell is something we've used, installed, or built for a customer's truck ourselves.

What we do

We specialize in performance parts, exhaust upgrades, and apparel for Cummins, Powerstroke, Duramax, and select boosted import platforms. If we wouldn't put it on our own truck, we don't sell it.

Why we exist

Diesel performance got expensive and impersonal. Big distributors moved everything online and stripped the trust out of it. We're trying to bring that trust back — fair prices, honest fitment info, and real techs behind the parts.

Where we are

Houston, TX. Shop visits by appointment. For questions, fitment, or installs, reach us at dieselsrus1943@gmail.com.
