I'm going to picking up a new silverado z71 4by with the 6.2 and 6spd. going to be putting a 6" bds kit with 35" nittos and i dont think ill be going bigger then that. itll be drivin mostly between

 

city and home which is down back country dirt roads with the occasional highway trips. its not going to be towing anything to heavy. im trying to figure out what the best gears would be, i

 

was leaning towards 4.10s but i need advice since most of the modifying ive done has been with engine performance. I'd appreciate the help :thumbs:

make sure you get the package that comes with the 3.73s from the factory and you'll be good to go. Then get a good tune after you put the lift and tires on.

 

If the truck comes with 3.42s (which i think is possible now... not sure) and you're going to re-gear, then 4.10s would be a good gear to put in there. But if the truck has 3.73s stock then it really wouldn't be worth the money, especially since you said you're not towing anything heavy.

These guys arent kidding its such a smart move to make sure you get the 3.73s and not worry about gearing. Not only will it save you upwards of a couple grand but you dont have to tear into your brand new truck either, or finding someone competent enough to do it and responsible enough to help you out if they screw it up.

Matt is one guy that wont steer you wrong. I just put my tires and lift on and regearing is in the works.

My truck however came with the 3:42. with 5.3L

I going to move up to 4:30 as per Matts imput

Yeah originally i had the order set up for the z71 package that only allows the 3.42 but now that im thinking it over it costs an extra grand to have the max trailering package with the 3.73 but ill definately save that by not having to re-gear both diffs plus i get all the added electrical components from the package to. originally the dealership had it priced at 35k (canadian) before taxes hopefully ill get a similar or better deal haha

 

thanks for the help! :thumbs:

it will definitelyl be cheaper to get the max trailering package from the dealer with the gears you need than to have to replace gears down the road.

      New Member Just Bought a Vtrux

      By Artemis · Posted

      Great info here thank you. I just joined, we have a 2014 Silverado truck we bought about 4 years ago with less than 5,000 miles on it. It has approximately 24,000 on it now. It appears to have all the standard issues that people are talking about. Occasional charging problems especially using 110 volt, occasional blinking triangle where nothing will turn on when first starting the truck but it will reset itself if you wait 10 to 15 minutes. Noisy coupler between the flywheel and the generator. Our truck is speed limited to 74 mph, is there any way to change that? The latest issue we have been dealing with is when driving long distance on the highway at full speed the generator does not keep the batteries charged. The meter will go into the yellow/red border Zone for charge status and the yellow triangle will illuminate solid but the generator will not keep the battery charged, not sure why the controller doesn't tell the gas engine to increase RPM to increase generator output it usually stays well below 25 kilowatts even though the battery is discharging and I have to slow down the highway to 45 mph and eventually pull over and let the truck idle to charge the battery so I can continue driving at speed. Has anyone had this issue before or have any idea how to diagnosed it? When via Motors was around it they were very helpful at troubleshooting. This becomes much if the Terrain is hilly and you're towing a small trailer

      Tonneau cover that does not leak water

      By Z45 · Posted

      I have the GMC accessory (REV) cover installed by dealer. Ordered with the truck.  They did a very good install job, can't find a single issue. Some water gets in around the tailgate but no where else.  You can see daylight around the tailgate but that's not the covers fault.  Installation is means everything. Guys at my dealer were seasoned pros, not inexperienced here today good tomorrow types, like many dealers employ for these jobs.   I don't mind paying for a professional job.

      Like others have said, they will all leak. Mainly at the corners.   I have owned several and the best has been my current one. Revolver x4

      LCA bolts

      By calgator73 · Posted

      About 8 months after an alignment job by the dealer I started experiencing a pretty significant clunk in the front end on hard left hand turns usually parking lot speeds almost at lock.  Occasionally get the same on hard rights too.   Discovered that the lower control arm attachment bolts are TTY and only to be used for a single use. And then I found some evidence of a TSB that indicates you can over torque those fasteners to about 130 foot pounds.   Asked a local shop to investigate and they found 3 out of four bolts loose and retorqued.   I've ordered the MOOG    K100421 lower control arm bolt kit that is completely reusable and not TTY.    Is the 80 ft pounds a realistic number?  Anyone have experience with those bolts?

      Brake Bleeding Procedure on 2026 Silverado 2500

      By davester · Posted

      subscribe to alldata.com, that will have gm's brake bleeding procedure.  and what you have to do likely varies, as if you just replaced a caliper and the MC didn't go dry, you most likely can just do a normal bleed on that corner, but if you disconnected lines at the MC or the abs unit, or let the MC run dry while doing work, you'll have to do a more extensive/complicated bleeding procedure.
