S&S Diesel Motorsport injectors for the 2019–2021 6.7 Cummins. Available in TorqueMaster stock replacement for both Standard Output and High Output configurations, plus performance sizing from 50% through 200% over stock. All new — no reman option on this platform.
The 2019–2021 6.7 Cummins is available in two factory power configurations — Standard Output and High Output. These use different injector specifications and are not interchangeable. Select the correct TorqueMaster variant for your truck's output configuration. If you are unsure whether your truck is Standard Output or High Output, check your door jamb sticker or contact us at info@hardwayperformance.com before ordering.
Performance sizing from 50% through 200% over stock covers the full range of street and mild competition builds on the 2019–2021 platform. Larger flow rates require an upgraded or dual CP3 system, lift pump upgrades, turbocharger upgrades, and custom tuning calibrated specifically for your injector size. Oversizing injectors without proper supporting components results in poor drivability and excessive smoke. When properly matched these injectors deliver clean, controlled power.
On connecting tubes: S&S recommends replacing the connecting tubes any time injectors are changed. Contaminated fuel failure is not covered under warranty by any fueling company. Cleaning existing tubes is an option if budget is a concern, but replacing them is the right call. Feed tubes are available to ship with your order.
Not sure which size is right for your setup? Contact us at info@hardwayperformance.com with your year, output configuration, overall use, turbo combination, and HP goals and we will make a recommendation.
Individual injectors are also available for single injector replacement. If you are replacing one failed injector rather than the full set, select the single injector variant for your size and output configuration. Note that individual injectors should be matched to your existing set — contact us at info@hardwayperformance.com if you need help confirming compatibility.
