What problem does this kit solve?

The OE design routes ~200A through a small bolt/nut inside the intake. Over time it can deteriorate, arc, and break off—risking engine damage. This kit removes that failure point.

Do I need tuning?

No. The kit keeps the factory control strategy and heater performance for reliable cold starts.

What’s included?

High-current external connection components, hardware, and install pieces tailored to the 6.7L Cummins layout. See the product page for the exact contents.

What years does it fit?

2007–2024 Ram 2500/3500 pickups and 3500/4500/5500 cab & chassis. When possible, confirm with VIN.
