Maximize the performance of your 6.6L Duramax with Dynomite Diesel Performance Injectors. Spanning from the early LLY to the high-output L5P, these injectors are engineered for everything from reliable daily towing to elite 1,200+ RWHP competition builds. Featuring advanced SAC nozzle technology on high-flow models, DDP injectors provide superior fuel atomization, improved throttle response, and the durability required for heavy-duty diesel applications. Every set is precision-balanced and matched to ensure peak engine reliability on the street, the track, or the pulling pad.

Features
  • Every set is precision-balanced and flow-matched
  • Options available from 15% (50HP) up to 300% over flow for record-breaking builds
  • High-flow models feature durable SAC-style nozzles
  • Available in 100% Brand New (No Core Charge)
  • Available in high-quality Remanufactured units
  • Supports everything from daily driving/towing to extreme competition-ready rigs
  • Brand New units carry up to a 2-year warranty
  • Remanufactured units carry a 1-year warranty
Notes
  • Identify Your Engine: Ensure you select the correct Year Range and Engine Code (LLY, LMM, LML, or L5P) as these fuel systems are not interchangeable.
  • Supporting Upgrades:
    • 50HP - 75HP (15-30% Over): Safe for stock trucks; a Pyrometer is highly recommended to monitor EGTs.
    • 45% Over and Up: Modified or dual CP3/CP4 pumps, high-flow lift pumps, and significant turbocharger upgrades are mandatory.
    • Competition Sets (100% - 300% Over): Race use only. Custom tuning and a completed Race Waiver are required before the order can be finalized.
  • Policy: Final Sale. Once installed, injectors are non-returnable and non-refundable due to sizing errors. Confirm your power goals with your tuner before purchase.
  • Emissions: Not for sale or use in California.
