BD Diesel AFC Spring Kit - 1994-1998 Dodge 12-valve/P7100 Bosch Pump

This BD Diesel AFC Spring Kit is designed for the P7100 Bosch injection pump found in 1994-1998 Dodge 5.9L Cummins engines. The kit includes a medium and light tension AFC spring, along with various screws and Allen wrenches needed for installation. These springs help ensure that the Air Fuel Control (AFC) system can achieve its full travel range with a reasonable amount of boost, which is crucial for controlling exhaust smoke without sacrificing power.

The longer spring design provides a bit of pre-load, allowing for smoke adjustment by turning the star wheel without impeding the AFC link's full travel. This means you can fine-tune your engine's fuel delivery to reduce smoke under load while still getting the power you expect at typical boost levels. It's a well-built component aimed at helping you get the most out of your diesel engine's performance, especially when pushing it beyond stock settings.

Please note that modifications to the P7100 pump require a qualified pump technician for installation. Improper installation can lead to excessive heat, smoke, or poor performance. This kit is not CARB approved and cannot be shipped to California.
