The only way to get the 2nd battery from the factory is with the duramax.

 

If  'OEM' setup is desired, it will require use of the duramax parts. 

 

"Battery, heavy-duty dual 730 cold-cranking amps/70 Amp-hr, maintenance-free with rundown protection and retained accessory power
1 - Included and only available with (L5P) Duramax 6.6L Turbo-Diesel V8 engine."

 

Gas and diesel can both have the 220A alternator (replacing the 150A).  It is included with the snowplow prep, but available without snowplow prep. 

Dual alternator (one of each) requires the diesel.

 

 

If it is for use with a winch (or similar) when the truck will be running I wouldn't bother to use an isolator. 

Just hook it up like the duramax. 

 

Used to run auxiliary power for a long time (like at a campsite) with truck not running, then an isolator might be wise.

I just did a quick build and price on GM's site and at least on the Canadian site it allows you to option a 6 liter truck with an auxiliary 730 CCA battery.... and the American site allows it too.

Why do you think you cannot get dual batteries in a gas truck? Every GM HD truck I have ever ordered I ordered dual batteries, it is still a option today...

Seems like a good price if it is an auxiliary and not just a change in battery

 

I wonder if they change the primary battery to a 730 as well.

(duramax is a pair of 730 cold-cranking amps/70 Amp-hr: std is 720 cold-cranking amps/80 Amp-hr)

Pretty sure they aren't calling one battery in the truck an auxiliary lol.

They are both 730's and yes it includes dual batteries. Gas 6.0...

I think I've let myself be mislead by the order guide entries.  

 

This entry:

"Battery, heavy-duty dual 730 cold-cranking amps/70 Amp-hr, maintenance-free with rundown protection and retained accessory power
1 - Included and only available with (L5P) Duramax 6.6L Turbo-Diesel V8 engine." 

 

 

is a couple lines above this entry:

"K4B         Battery, 730 cold-cranking amps, auxiliary
1 - Not available with (L5P) Duramax 6.6L Turbo-Diesel V8 engine." 

 

And I ignore the entry for rpo KB4.

Sorry about the confusion. 

 

Although at the end of the day it seems the OEM dual setup is the duramax setup....with the 730's..

Wow, the 220A alternator is standard with a snow plow prep now? I feel cheated...

I have the dual batteries cause I could...I have a winch, I run cold climate from time to time (spins the starter easier), and mainly because I could.

Available and included content is ever - changing.

 

One of the things that can motivate us to update from time to time. 

 

I added the 220 to mine, just because I could.

220 is available as a stand alone option as well.

That's fine, but I only got the 160A with the plow prep package in 2012! Not that I need it...

2015 is when the snow plow prep trucks with 6.0 got upgrade to the 220A alternator.

      OCI, not when but why?

      By Grumpy Bear · Posted

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.

      Looks nice. I still have my 2000, 1500. Bought a 2025, 1500 for retirement. Feels solid. These trucks have a bad rap on the internet. My brother has a `24 1500, 5.3 with 52,000 miles. No problems at all. Mine hasn`t either but mine`s only at 12,700 miles. Have seen some of these things with 100,000 miles with no problems.

      Howdy! New to the forum of course! My name is Casey, just picked up a 2024 high country midnight edition. First “new” truck in 24 years for me. Driving a 1998 Z71 since 2002. Have been on the GMT400 forum with lots of good info and help there. Nervous about driving these newer trucks and all their electronics…. Did a lot of work on the Z71 myself over the years. New truck is definitely a nice upgrade after 24 years. Photo of the old and new, still keeping the Z71 - has 320,000 miles on her and still running well!
