Engineered specifically for 2007.5–2010 Dodge Ram 3500, 4500, and 5500 Cab & Chassis commercial work trucks powered by the 6.7L 24-Valve Cummins turbo diesel engine without SCR (Selective Catalytic Reduction), the BD Diesel Premium Remanufactured Fuel Injector (1725571) restores factory injection precision and power delivery. Commercial duty cycles, heavy payloads, and severe duty towing accelerate common rail injector wear. Over time, internal ball-seat erosion, control valve degradation, and nozzle orifice enlargement result in excessive return flow, difficult hot starts, black smoke emissions, injector knock, and diagnostic trouble codes (such as P0087 low rail pressure).

Unlike budget remanufactured alternatives that merely clean or lap worn internal surfaces, BD Diesel’s Premium line replaces all critical wear items with brand-new Bosch original equipment components, including the nozzle, electronic solenoid, and high-pressure control valve. Assembled in a certified cleanroom environment by Bosch-trained technicians, every completed injector undergoes extensive validation on a specialized Bosch EPS 815 test bench. Tested across eight distinct engine operating points—from low idle and pre-injection to full-load peak rail pressure—each injector is matched to an exacting +/-2% flow tolerance (significantly tighter than the OEM factory allowance of +/-5%), delivering balanced cylinder-to-cylinder fueling, smooth idle stability, optimal fuel economy, and OEM-spec exhaust emissions.

Key Features & Benefits

• 100% Brand-New Bosch OE Components: Every premium injector receives a brand-new Bosch nozzle, control valve, and solenoid assembly to eliminate premature failure and leakage.
• Precision +/-2% Flow Tolerance: Calibrated to an industry-leading +/-2% flow variance (versus the +/-5% OEM standard) for balanced cylinder output, smoother engine idle, and reduced torsional vibration.
• Tested Across 8 Operating Conditions: Fully validated on an authorized Bosch EPS 815 automated test bench across idle, part-throttle, torque peak, pilot injection, and full-load rail pressures.
• Restores Lost Power & Fuel Economy: Eliminates high fuel return rates, cures hard starting/long cranking issues, stabilizes common rail pressure, and clears injector-related check engine lights.
• Cleanroom Assembled: Built by certified technicians in a temperature and particulate-controlled cleanroom following strict Bosch remanufacturing procedures.
• Complete Seal Package Included: Pre-packaged with brand-new copper combustion chamber crush washers and external body O-rings for an immediate, leak-free installation.

Vehicle Fitment & Installation Notes

• 2007.5–2010 Dodge Ram 3500 Cab & Chassis – 6.7L 24V Cummins Turbo Diesel
• 2008–2010 Dodge Ram 4500 Cab & Chassis – 6.7L 24V Cummins Turbo Diesel
• 2008–2010 Dodge Ram 5500 Cab & Chassis – 6.7L 24V Cummins Turbo Diesel
• Fits Model Years: 2007.5, 2008, 2009, 2010
• Fitment Notice: Engineered strictly for Cab & Chassis (commercial frame) models without SCR/DEF systems using Bosch cross-reference 0986435519. Does not fit standard Ram 2500/3500 pickup truck beds (which use standard pickup injector SKU 1725518 / Bosch 0986435518). Verify the 8th digit of the VIN and cross-check the Bosch part number stamped on the injector body before ordering.
• Installation Tip: Always install brand-new high-pressure fuel connector tubes (feed tubes) whenever replacing common rail injectors; torque injector hold-down bolts to 89 in-lbs (7.4 ft-lbs) before torquing fuel connector tube retaining nuts to 37 ft-lbs to ensure proper seating and prevent high-pressure fuel leaks.
