Duramax 01-04 LB7 Nozzle Set: Upgraded nozzle set flowing at 25 percent over, approximately 50 RWHP over stock. This nozzle set is capable of 600-625 RWHP with proper supporting modifications.
These nozzles are safe on stock trucks with little to no modifications. Excellent street manners and MPG. Recommended for a mild bump in performance as well as those who primarily tow with their vehicles. Pyrometer recommended. Sold as a balanced and matched set.
Note: The fuel injector lines on the LB7 are notorious for rusting and causing issues with the injectors. For this reason we highly recommend replacing your injector lines while changing injectors or nozzles if the lines have not been changed within the last 40,000-50,000 miles. The part number for our brand new line set is: DDP LB7LINE-SET
