Looks like that might be for 11-13. Another website says 11-14

Funny. My truck is a 2016 Silverado Z71 w/ 5.3L. This programmer came from the dealership that sold me the truck brand new, already lifted and 35” tires. This is what they used to program it. Worked fine.

I have 4.10s and 5.3/6.

I run around 1800-2k at 75-80.

Last time I took it to Orlando doing 75 average I was getting 18mpg.

So while on the freeway will the truck hold 6th gear now that you did the 4.11 or does it still slow down , lug then down shift ?

Nope.

My truck holds 6th gear unless I want to pass and then I need to push pedal to point where I will downshift.

I drive to Orlando a lot (2-1/2 hrs one way) and I’m usually running 75-80 on cruise control.

I feel your pain! I did same thing but guy who did my gears owns a shop and has been doing this his whole life. He told me it wasn’t worth going any higher than 4.10s because I don’t tow anything. I went with him on it and called it day. 

 

You definitely want to ask!

Do you think you have regained your trucks stock towing capacity with the 4.11 ?

Because I do tow and going to the lake with the boat is up hill.....so is going to the dunes with the side by side or toy hauler. Hell I live in a valley so it's all up hill from here?.

I do feel like the truck is back to how it was stock with 4.10s.

I don’t really tow but if I had to I wouldn’t be concerned.

Couple that with my tune and it’s awesome. I like what Diablew did for my truck.

Hey thanks for all the info, this is good stuff..

I did plan on getting a custom tune from Black Bear first but I think they stopped responding to my emails. I don't know maybe I ask too many questions.

LOL.

I thought about them but I decided to go Lew.

He’s legit listen to me over stupid stuff (I ask a lot of questions too).

Good luck. Either way you’re going to love gears. I am very happy with the decision. East Coast Gear Supply is who I ordered from; they’re vendor on here. I think at time I paid $900 for gears and $800 installed.

You’ll be happy with 4.10 gearing.

 

4.56 will make it seem a little stronger at low speeds with light pedal, but it will also make the engine be at a constant higher rpm  on the highway  2,300-2,400 rpm at 75mph.

 

With the 4.10 you may give it slightly more pedal to get the same “strength”, but here is the thing; when you actually get on it, it will downshift and put you back into the power band of the engine making it every bit as strong as it would be with the 4.56.

 

if you’re towing anything heavy, loading down and working the hell out of your truck or if you are going to go up in tire size (at all) then 4.56 are merited. Other than that 4.10 is enough.

 

yes, tune it. Absolutely. Sooner rather than later.

Here is my drive to Orlando today.

When I got there my actual mileage was about 17.1 for 2-1/2 hours on highway.

Is it necessary no. You’ll just have a check engine light on all the time. as soon as you swap gears your drivetrain warranty is gone. So you might as well calibrate the ecm for the gear swap to get rid of the check engine light. Since you’re doing that you might as well tune it and get some more performance out of the thing. Gears will wake it up for sure but without a tune you’re still leaving a lot of performance on the table

 

whos telling you first gear will be useless and what do you intend to use first gear by itself for?  Sure your rpms will go up but so will your gas mileage. 300 rpm is nothing. As said above with your setup I’d go as big as you can. I wouldn’t go less than 4.56. All a bigger gear is doing is getting you back to what your truck would be stock. 8” lift on 35’s means you’re rolling around in what a stock truck would feel like with 3.08s. A 3.73 gear would get you back to 3.42. A 4.10 gear would get you to 3.73. A 4.56 gear would get you to 4.10.  You want a big gear to move all that added weight efficiently and easier. 

 

Im similar setup as yours. I have a 7” lift on 35s and I’m getting 4.56s put in on the 27th. I can’t wait.

Can you give us an update on your gears when you get it back.

that's not bad at all....pretty good actually ?

I was told  I should wait until after my trip to the sand dunes to get the gears because of a break-in period. They said no towing or long trips for at least 500 miles

I don't have a full review as of yet as I only drove it from the shop to my house last night which was maybe 15 miles all hwy.  I can tell you that it feels like a completely different truck.  It moves absolutely effortlessly.  They weren't able to calibrate the new gear ratio in my tuner (I suspect because the battery was low) so I didn't know my actual speed and couldn't verify it with GPS because my son was in the back seat on my phone playing games.  I was going with the flow of traffic on a 70mph hwy and my speedo was reading 89mph.  My guess is at 70mph my rpms were right at 2000rpm.  I'll have more info on that later today after I get everything synced with my tuner.  I can confirm though that with the ecm not knowing the new ratio I didn't get a check engine light.  Mechanic says some do it and some don't.  But the tranny doesn't like not knowing the ratio for sure because it short shifts real bad.  Truck maintained 6th the entire way home where as before on the slightest incline it would down shift.  It doesn't do that anymore.  With the rpms being up higher, the slightest throttle input just makes the truck go.  Its really pretty sweet.  Like I said Ive only driven it maybe 15 miles but can tell you its worth every penny paid.  I cant wait to hook up to my toy hauler and see how it tows.  I have to baby it for 500 miles before I do any towing so I'll post up about that eventually

Jacoby did you get PM from me or did I sent it to myself?

    • 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.  
    • 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. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
