S&S Diesel Motorsports Fuel Injector Set

S&S Diesel Motorsports Fuel Injector Sets: Common-Rail Precision Redefined

When serious diesel builders need a complete fuel injector set, few names carry the weight of S&S Diesel Motorsports. Drawing on deep OE diesel injection and engine development experience, S&S has positioned itself as a world leader in high-performance common-rail diesel injection — and their fuel injector sets are the clearest expression of that expertise.

What Sets S&S Fuel Injector Sets Apart

The difference starts on the test bench. Fuel injector sets from S&S are not simply drop-shipped from a supplier — they are built and validated in one of the most advanced fuel labs in the aftermarket. S&S injectors are built using new or fully remanufactured bodies and are individually calibrated and flow-matched, resulting in more consistent fueling, improved drivability, and better reliability under high fuel pressure compared to factory injectors.

That level of validation goes well beyond what most competitors offer. S&S Diesel Motorsports uses multiple in-house custom-built test stands to thoroughly validate every product, while their in-house fuel laboratory measures injection-rate shape and five injection events simultaneously. This is the kind of testing normally reserved for OEM development programs — applied to the aftermarket.

Platform Coverage and Performance Tiers

S&S Diesel Motorsports fuel injector sets are engineered for the three major diesel truck platforms: Cummins (5.9L and 6.7L), GM Duramax, and Ford Powerstroke (6.4L and 6.7L). More importantly, S&S offers multiple injector options designed for stock replacement, towing, street performance, and high-horsepower builds — with some sets ranging from stock flow capacity all the way to 500% over-stock flow on platforms like the LBZ Duramax. This tiered approach means there is an S&S injector set for a daily driver just as much as for a competition sled-pulling build targeting well over 1,000 horsepower.

New Units, Not Just Remans

A key distinction worth understanding: many S&S Diesel Motorsports injector sets for Ford Powerstroke and Duramax applications are fully new units — not remanufactured cores. All injectors feature optimized nozzle-to-body tolerances and precise internal adjustments to optimize performance and reliability. For Cummins applications, S&S offers both new and remanufactured options, with remanufactured sets using genuine Bosch SAC00 injector bodies where applicable — including CARB-compliant configurations.

Built for Builders Who Demand More

S&S Diesel Motorsports fuel injector sets are trusted by top tuners, race teams, and diesel enthusiasts around the world precisely because the brand refuses to cut corners on components or calibration. Whether you are replacing a failed OEM set, building a dedicated tow rig, or assembling a high-horsepower competition truck, an S&S fuel injector set delivers the consistency and outright flow capacity that demanding builds require.
