2003-2004 LDS Super Stock Fuel Injectors, For 5.9L Cummins, New Fuel Injectors *NO CORE CHARGE*

Need to replace your injectors but not sure if oversized is anything you need? LDS presents the LDS 5.9L SuperStock Injectors. These are superior to the OE Stock Injectors at a way better price!

LDS 5.9L SuperStock Injectors are the perfect option for a slight increase in power without jumping into a full engine upgrade!
SuperStock's are engineered to run on your completely stock truck. Absolutely No modifications are needed.

The SuperStock's provide a minimally increased fuel supply resulting in more power at full throttle, performance and better fuel economy. SuperStock's start out as BRAND NEW OEM Genuine stock injectors. Each nozzle is professionally lifted using AFM (Abrasive Flow Machining) to the desired flow percentage and the injectors are meticulously hand reassembled and tested. Each injector is tested under full operational range using professional grade systems. Your set is then cautiously selected to create a narrow margin flowing group. LDS is industry leading in supplying our customers with injector sets with a balanced spread of 3% or less. The set comes with a full analysis and calibration flow summary sheet.


These injectors include the copper washer, o-ring, and return line clip.

When Replacing Injectors it is recommended to replace fuel crossover tubes (See Drop Down)
