About River City Diesel
Founded in 2006 and headquartered in East Peoria, Illinois, River City Diesel (commonly known as RCD Performance) has built a dedicated following among diesel truck owners, fleet operators, and competition builders. Operating out of the heart of the Midwest, this privately held company grew from a diesel engine machine shop into a respected manufacturer and supplier of high-performance diesel parts, with a particular focus on Ford Powerstroke, Cummins, and Duramax platforms.
What sets River City Diesel apart is its hands-on engineering philosophy. Rather than simply sourcing and reselling parts, the RCD team develops, installs, and tests the components they sell in real-world and competition environments. This commitment to validation means every part that leaves their facility has been proven under the kind of stress that diesel enthusiasts actually put their trucks through — whether on the highway, the work site, or the race track.
Diesel Fuel Injection Expertise
River City Diesel has earned a strong reputation in the diesel fuel injection space. Their CPX fuel injection pump lineup for the 6.7L Ford Powerstroke is a standout example — available in stock-output configurations as well as high-output variants capable of supporting builds up to 850 horsepower. These pumps are engineered with precision and validated on the bench before shipping, reflecting the brand's commitment to quality at every stage of production.
Engine Components Built for Performance
Beyond injection, River City Diesel produces a range of critical engine components designed to address known weaknesses in popular diesel platforms. Products like their billet low-pressure oil pump gear sets for the 6.0L Powerstroke, front timing covers and oil pump assemblies for the 6.4L Powerstroke, and chromoly pushrod sets for high-lift valvetrain applications demonstrate a deep understanding of what these engines need to survive — and thrive — under modified conditions. Each component is engineered to precise tolerances and built with durable materials suited to the demands of diesel performance.
Intake and Turbo System Components
River City Diesel also manufactures stainless steel intake components for diesel trucks, including their 304 SS intake wye kits for the 6.7L Ford Powerstroke. These kits replace factory plastic tubing with robust stainless steel hardware, running from the intercooler all the way to the engine. This type of upgrade is a popular choice for diesel owners looking to improve reliability and support higher boost levels on modified trucks.
A Trusted Name in the Diesel Community
With years of experience in diesel turbocharger service, fuel injection rebuilding, engine machine work, and parts manufacturing, River City Diesel occupies a unique position in the aftermarket: part shop, part engineering firm, and deeply embedded in the diesel performance community. Whether you're maintaining a work truck or building a competition sled puller, RCD Performance delivers parts that are engineered by enthusiasts, for enthusiasts.
