You guys planning on doing a re-gear should definitely do at least a 4.10. I'm the OP for this thread and I've been researching it for quite some time now. Every shop and person I've talked to recommends at least a 4.10. If your truck came with 3.08, 4.10 will be night and day difference. If your coming from 3.42, 3.73 isn't a big enough difference to justify. I've been told by everyone that's regeared that you can never have "too much" gear. Yes gas mileage will suffer a little bit, but you don't go buying a truck and putting bigger, heavier tires on it to get good fuel economy. Not to mention, if you put bigger tires on and decide to tow something, you will be doing it with ease.

 

Anyways, that's just my take on it and what I've come up with. I will be getting my tires soon and I'm planning on doing a 4.10 swap. I will post my thoughts on here as soon as I get it done.

Imo

Lift rear-end swap

And put a blower on your colorado

[emoji106] [emoji106] [emoji106]

While the colorado is going to be the speed demon it will eventually get a snail.... All i want is my silverado to put down 500 and the colorado to out down anything above 700. I dont think i can drive much more then that.

 

I hate the "imma build a 1000hp truck but someone else drives ut at the track" thing that is popular where i am from.

 

The colorado is a crew cab but it was my first truck so it has a special place in my heart lol

 

 

Back to the silvy.

 

My dilemma is that im still torn between 6 and 4 inches of lift.... I know BDS makes both but dang this is a hard decision

If i go 35s it will be 4.10s

 

And if i wanted good gas mileage i wouldnt have bought a truck... Much less plan on a blower and lift lol

Yeah but it was nice before the lift/tres/blower when I could get 21mpg around town and now I'm lucky to get 12-13, hahaha.

I did visit there site once. What does there tunes run in person

I bought the AutoCal and had them do a tune for me via email so I have no idea how much an in person tune costs. Try looking for "Jennabear" on here, she works at Black Bear and can answer just about any question you may have.

If you could keep your foot out of it!!!!

 

From what i have seen 4.10s is the go to gear. I went from 3.73s to 4.10s in my colorado and it was a slight difference... I can imagine 3.08 to 4.10

Ok thanks. I hate messing with computers and email's, , so I would drive a few hrs out of my way to do it in person, ,

when you guys are re gearing are you just swapping gears in the rear end or are you re gearing in the front too?

If you have 4wd you have to do both front and rear. Should you only do one and engage 4wd, bad things will happen.

You HAVE to do both.... The difference in rotation speed will flat out shatter your transfer case.. I have seen it happen. You do both.... If you can do both at once you pull the fuse for your 4WD until you do the front. I will be doing both at once.

yea thats what i always figured. the front differential must be a huge project to do. the 3.42 for me pushes 33s around just fine. 275/70/18 duratracks are only 20 lbs heavier than stock each tire.

I actually think with these new pickups, the front is the same as previous generation. It's the different housing size of the rear diff thats causing havoc for everyone wanting to do a gear swap.

My current setup up on a 2015 Silverado 5.3 is 4.10 gears, Magnuson blower, American Racing Headers. The truck has 35's on 22's and the 4.10 are perfect. I previously had 33's on 20's with the 3.08's and they were horrible. If you are going to stay all motor, I would do 4.10's on 33's, with an intake and exhaust, tune you will be happy. Just my opinion

Where did you get all your motor work done?

Yes the fronts are the same, the rears are totally different and when your in the rear minas well change the G80 crap out. I love my truck but looking to sell the magnuson and get the procharger

Why do you want to sell yhe magnuson?

Just want more power and the sound of the Procharger. The magnuson is nice but I want something a little loud.


I did the work myself, except the gears, pretty easy to do, I just had to pay someone to do the tuning.

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.
