99-06 Battery Relocation

99-06 Battery Relocation

Postby LOWENUFF [OP] » Jun 10 2021, 10:26pm

Has anyone relocated their battery to the front passenger side of the truck bed on their 99-06 Silverado or Sierra 1500? I'm wanting to move my 2003 Sierra 1500 but need some guidance on what exactly is needed and where to run the cables to. I have a general idea how but I'm trying not to mess anything up.

I would rather try and talk you out of this first. What purpose do you think this will serve, move weight from the front, closer to the rear?

You need to make and run a new power cable from the new mounting position back to under the hood. Then run a new ground (through the bed) to the frame, as long as its a ground that won't interfere with other electronics you already have. You will need to get an enclosure that's going to keep it weatherproof, and strong enough that whatever you put in your bed won't possibly damage it. It really is simple, but in all honesty it creates so many other potential problems.


Do you have a v6? There's no way you are losing traction year round. Is this a winter issue? A 40lb bag of sand is $3. You can fill the bed with snow. If this is about putting more weight over the rear for the winter, what I do is use a 5 gallon bucket or two filled with sand and ratchet strap it around the tailgate.

Do you have one of those carpeted beds that never gets used? You really would be limiting your bed-use potential in the future. Not only for size, but also you better strap everything over 5lbs down from then on. You would have to plan for the worst, and that means heavy braking stops where anything could fly forward.

You then have a longer battery cable and ground that have the risk of getting frayed or damaged. If you get in an accident you now have this longer battery cable that could short out, (especially with it being so close now to the tank).

Between the enclosure, and extra cable, you would probably add at least 20 lbs.

The only way this even might be practical is if its a weekend toy/(2nd truck), or full on race truck. Even then it still just doesn't seem worth it.

What exactly is the purpose for wanting to do this? I would bet there are better ways to accomplish what you are wanting to do.

I'm pretty sure he wouldn't need to move it for that. It also seems odd to plan for such an in-depth project and have trouble with knowing how to move the battery. Could be though.

Some people relocate some don’t just depends on the tub or if he is going for like a show style engine bay with just a bed cover to hide battery etc.

I agree though no idea why he would do this.

Its bagged on 22s right now... had 26s when I bought it and has no inner fenders whatsoever. The battery tray is welded in much higher than stock and only a small battery fits... not to mention there's no battery tie down either.. This would be mainly for safety purposes plus aesthetic purposes as I plan to clean up the engine bay. Yes the bad is tubbed... one complete side to side tub and I have a bed cover. No need to worry about stuff sliding around

I would personally try to weld the tray lower and move from there rather than relocate all the way to the bed. But it is just two wires you need to connect and run them back and along the frame
