Industrial Injection 21C312 Reman Stock 6.7 Cummins Mid-Range Cab & Chassis Injector Pack with Tubes

The Industrial Injection 21C312 is a complete, all-in-one remanufactured injector kit engineered for the 6.7L Cummins Mid-Range Cab & Chassis platform. This kit takes the guesswork out of a full injector replacement by bundling everything needed for a clean, reliable install into a single part number.

What's Included:

• Six (6) Industrial Injection Stock Remanufactured 6.7L Cummins Injectors
• Six (6) Genuine Bosch Connecting Tubes
• Copper washers and O-rings

Key Features:

• Built, calibrated, and tested in an authorized Bosch facility
• Balanced to tighter tolerances than original manufacturer specifications for a smooth, clean idle
• Direct OEM replacement — no tuning required
• Includes OEM-grade Bosch connector tubes (F00RJ01572 / F00RJ01831) or Cummins equivalents (3979419 / 5346206) to protect your warranty
• 2-Year Unlimited Mileage Warranty
• $100.00 core charge per injector — fully refundable when cores are returned within 90 days

Important Installation Notes:

• Call in with your engine serial number prior to ordering to verify correct application
• Replacing connector tubes during any new injector installation is strongly recommended to prevent contamination-related failures
• Only Bosch or Cummins OEM connector tubes must be used — the use of aftermarket connector tubes will void the warranty

Industrial Injection's Stock Reman injectors are the ideal solution for 6.7L Cummins Cab & Chassis operators who demand OEM-level reliability with the added confidence of professional remanufacturing, precision calibration, and a best-in-class warranty.
