Power Distribution Module

Genuine OEM Power Distribution Modules & Fuse Box Assemblies

A failing power distribution module can take down an entire electrical system at once — lights, gauges, ECM communication, even starting circuits can all trace back to a single bad PDM. Because it sits at the center of the truck's wiring, guessing wrong on a replacement means more diagnostic time, not less. That's why every module in this collection is genuine OEM, matched to the manufacturer's original part number.

What's in this category

This collection covers power distribution modules and fuse box assemblies used across heavy-duty trucks, including:

• Power distribution modules (PDMs) — the central fuse and relay hub that routes power to the truck's electrical circuits
• Fuse box assemblies — complete housing units with integrated fuses, relays, and circuit protection

Why order your PDM here

• Genuine OEM only — every module is matched to the manufacturer's original part number, not a generic equivalent
• Built for cross-reference — listings include the exact OEM number so you can verify fitment before you buy
• Fast turnaround — ships quickly to keep your truck off the lift and back on the road

FAQ

What does a power distribution module do? It's the central hub for a truck's electrical system, housing the fuses and relays that route power to lights, gauges, the ECM, and other circuits. A failure here can affect multiple systems at once.

Signs of a failing power distribution module? Intermittent electrical faults across unrelated systems, dash warning lights with no clear cause, blown fuses that won't stay replaced, or a truck that won't start despite a good battery.

How do I find the right part? Match the OEM number printed on your old module, or check your service manual/VIN, then search that number above.
