L5P Duramax New 50% Injector Set – S&S Diesel L5P-050-SAC-SET
Unlock reliable high-performance fueling on your 2017–2025+ L5P Duramax with this complete set of eight brand-new S&S Diesel Motorsport 50% over injectors. These injectors deliver the extra fuel volume needed for turbo upgrades, performance builds, and heavy towing while preserving the precise spray patterns and balance that keep the engine running smoothly and reliably.
Unlike many aftermarket options, these are built from new components (not remanufactured). S&S focuses on the synergy between the SAC-style nozzle and injector body so your engine receives fuel with consistent, controlled delivery across all cylinders.
Key Features
- Proprietary nozzle honing – Specialized process creates clean, consistent holes for optimized spray atomization
- Precision nozzle matching – Nozzles flow-matched to a strict 1% variance per set (Viscor SAE-J967 calibration fluid at 40°C and 100 bar)
- Injector flow matching – Complete injectors matched to within 3% variance across the full set
- Multi-point testing – Each injector tested at four distinct pressure and energizing points for responsive performance from idle to full load
- Aligned injection profiles – Rate shape carefully matched so timing and volume stay synchronized across all cylinders
- Custom build matching – Injector body specifications tuned to the specific 50% over nozzle flow rate
Fitment: 2017–2025 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD with the 6.6L L5P Duramax.
Important Notes: These injectors are intended for performance applications and require proper custom tuning plus supporting fuel system upgrades (lift pump, filtration, high-pressure pump capacity, etc.) for best results and drivability. Core charge applies. Backed by S&S Diesel Motorsport’s two-year unlimited-mileage warranty.
This is the entry-level performance step for L5P owners who want a meaningful fueling upgrade without jumping to the larger 100%+ sizes. The result is stronger power potential, more consistent cylinder-to-cylinder performance, and the precision engineering S&S is known for.
