Injectors

At Momentum Worx, we specialize in delivering high-performance diesel fuel injectors for the toughest engines on the road — including Caterpillar (CAT), Cummins, Detroit Diesel, and other top commercial applications. Whether you're running a 3406E, ISX, Series 60, or any other heavy-duty platform, we stock the fuel injectors that keep your engine burning clean, efficient, and powerful.

Our injectors aren’t just parts — they’re precision components tested to the most rigorous standards in the industry. Every injector we sell is built to meet or exceed OEM specs. That means drama-free installation, flawless fuel delivery, and countless miles of reliable operation — no leaks, no misfires, no guesswork.

From stock replacement injectors to high-flow performance sets for modified trucks, Momentum Worx has you covered. We understand what owner-operators and fleets need because we’re part of the same world — built around uptime, torque, and results. Our injector sets are always sold as FUL SETS and we offer expert support for any questions or build plans.
