Hey guys I’ve got a 2014 GMC Sierra 2wd 4.3 v6 on a 7inch lift 22x12s and 35s the trucks got 3.23 gears in it and when I bumped up to 35s from 33s it seems like it is always constantly searching for gears on the Highway or above 50mph I get around 13 mpg and I would like to retain that or get better if possible and I’m trying to decide wether regearing the truck would be worth the money and also what gears to go to If I get it done if 3.73 or 4.10s would be better I would like to retain as much gas mileage as possible but not have the truck struggling 24/7 when it hits a hill it just sucks the life out of it or on the highway trying to maintain a decent speed I have a cold air Intake exhaust and Diablo tuner please lmk what y’all think438e023f7bec8ca1d68c355f4fe6fe65.jpg

I think the consensus on these trucks is 4.56 when running 35s.  I have the 6.2/3.23/ 8spd and haven't regeared yet and I'm not really sure I need to.  The truck hauls ass still.

Truck looks good Dave.
If you can afford it do it.
The v6 has to be struggling with those tires.
Does the tuner help any?

My problem is that motor I’m just trying to find ways to get it back to how it was so you would go with 4.56 gears?

I wouldn't put any more money into that truck I would buy something more appropriate. You'll be lucky if you can break even on a sale.

I know I’m not going to break even with this but this is the truck I could afford at the time and now I’ve got it so close to being payed off it it would be stupid to get rid of it I’m gonna run it till it blows

Try this. Get out on the open Interstate/Highway and run in M5. Put her in cruise control and observe. This little exercise will let you know what it would be like to run with a 4.10:1 diff in high gear. See how much help that step is. A test that cost you nothing but time.

Thanks man I will do that and my biggest issue is the truck is always and I means always Reving up in the rpms to move like jumping the Rpms it will never just cruise and I can give it a little without it jumping in rpms to try to move

Needs 4.10's at a minimum for 35's.

 

2WD makes it's easy and costs way less than if you had a 4X4. You need to tune for that as well. It will adjust the shift points for the transmission.

      GM Hard Folding Tonneau by REV review

      By parthery · Posted

      Some clarification may help with some of these issues.   - Rev Industries is/was the division of BAK (now Realtruck) that makes covers under the OEM names.  So if you see one with a Ford logo on it, or if you are buying the GM Accessories cover, you are essentially buying a BAK G2 cover with different branding.   - Rev Industries now markets under RealTruck "Advantage."   - As of May 1, 2025, the Advantage covers now have a 5 year warranty.  Anything before that was a 36/36K warranty.   - Parts for the covers are available from Realtruck or BAK.  The email address to reach them is [email protected] or you can call them at 818-365-9000   - If the entire cover has to be replaced, you have to go through your local GM dealer.  Service dept opens an RO, notes the damage and submits it as a warranty claim.  Keep your paperwork handy so they can confirm when you purchased it and it's within the warranty timeframe.  Once the warranty claim is approved, Parts orders the replacement cover.  When it arrives at the dealership, service will remove and install the new one for free as labor is included under warranty.   - The Advantage covers are not the latest and greatest Gen 3 covers.  They still use the old school clamps, elevator bolts, etc...If you want the newer technology, consider buying your cover in the aftermarket world.  That way, if you have an issue you can deal directly with the manufacturer.   - Finally, RealTruck has a program with many of their authorized dealers that doubles the warranty to 10 years if the authorized dealer does the install.     Hope this helps.

      Upgrade to a 2026 AT4 with the 3.0L Duramax

      Welcome to the group!  My '22 just crossed 150K miles.  Runs perfectly.  Oil pump belt will be done in the next 30 days or so and onward hopefully for another 150K.  Love the truck.

      Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....

      Tire psi

      By jgaudet99 · Posted

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!
