StockPlus and Premium are different performance levels within our BD-Built injector options. Choose based on your goals for power and how you use the truck.

Do I Need New Fuel Lines When Replacing Injectors?

If lines are rusty, damaged, or removed during service, replacing them is the right move. Our zinc-plated lines are designed for corrosion resistance and exact fit.

What Is Included In The Install Kits And Lines Section?

Options include comprehensive injector install kits and OEM-spec components designed for durability, fit, and easier installation. Always confirm what is included on the specific product you choose.

Why Upgrade To A CP3 Conversion Kit On An LML?

CP3 conversion kits are designed to replace the CP4 with a more reliable CP3 option. CP4 failure can contaminate the fuel system, and repairs can be extremely expensive.
