This box of goodies just arrived. Will let y'all know how it turns out in a couple of days. The Tru-trac and rear gears are for the 2013 9.5" 14 bolt, i have a spacer for the diff cover and conversion u-joint to make it all go back together in the new 12 bolt, 4.56's for the front as well.

Been anywhere between 600 cash for a guy to do it at his house that runs a 4x4 shop 2 hours away and 900 to 1000 at the local shops around here. The problem i have around here is i pretty much have to push the job on them. They don't really feel comfortable with the new diff yet and that makes me leery.

I'm doing gears when I get home in a week. Going to 4.56 gears also. Having my shop do them. 600$ for front and back is a pretty good deal.

Curious to see how it goes. My install is getting delayed a couple of weeks due to work; back to the middle of the Gulf of Mexico for a couple weeks. I will have Black Bear working on the tune during that time so it works out better really.

Interested to see how this turns out. I know visually we wont be able to tell the difference. But I wonder what all needs to be done to adjust the computer for the speedo, traction control and stabilitrak

Everything should go smooth but we'll see. There are no issues now and the spedo is off over 9%. As long as all of the tires are turning the same speed as each other, which they will, the truck will be none the smarter. The issues you run into with the stabilitrak come into effect due to larger tire size and turning because there is more of a difference on revolutions in that situation, ran into this on my Tundra, this currently is not causing issues on this truck and don't plan to go to larger tires. The only thing you change with gears is the engine load and engine rpm, the spedo is already off so not an issue to me. In the long run the engine, tranny and diffs should be a lot happier. I will have a tune ready to go if needed but i don't plan on installing unless necessary.

Not yet, I am still in the middle of the Gulf of Mexico. Will be about 2 weeks before I get the chance. I am hoping one of the other guys gets it done though, the suspense is killing me.

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
