I have been trying to get a concrete answer about this for a while ... I have emailed/posted on GM facebook, asked on the full size forum page and also asked pickuptrucks.com. Why can't you get the 6.2 in a regular cab set up ???????? It seems you can get the top dog drive train in toyota ,ram not sure about 6.2 in fords reg cab ? Anyways I own a regular cab and it serves me very well, but I would love to have that big ole 6.2 in it! So what do you guys think ? It seems stupid not to offer it in all cab and beg configuations.

This is a video showing how the 6.2L sounds with headers and a corsa catback. The crew cab is my 6.2L, the 2005 extended cab is a 5.3L with a magnaflow muffler welded in.

Business related (sales, cost), government regulations (CAFE)

Has anyone put a cold air kit on the 6.2 and had any good results? Also what about these E3 Spark plugs that they swear gives you better power and more miles per gallon?

I just put on this http://store.knfilte...px?Prod=57-3058 on Thursday and after about 200 miles, I can tell a difference. The response is quicker and seems to run a lil bit better! I can't really answer about mpg because I have been punching it hard since.

 

But my kit is for an 08 sierra denali and I don't know if its the same as yours!

After I put mine on, I could tell better throttle response, and that noise, O that noise. Around that 3k RPM the noise of the engine sucking in air is amazing, not loud or annoying, just intoxicating. As far as MPGs, maybe a little, but not enough to make a huge difference. (see sig for mods)

I installed a 63 series K/N CAI along with Hypertech prog. both at the same time and mine really woke up and was pegging the speedometer's 120mph in no time and was lighting the tires with little effort. since then I have added wider tires (305/50/20's) and magna flow exhaust and TB spacer. I am able to hit 140mph on a straight road little wing and within 2 miles or less with the mph recorded on my navigation device I keep in my truck which is right on with my speedometer. I have not got a good 1/4 mile recorded time but it is quick IMA

Hi, Just wanted to update some info on my 2012 silverado L9H. I added the optima 34r battery and it fits with no modifications as shown. I also added the factory chevy red led light to the rear under the tail gate. It is a very close fit as you can see but it did work and looks good. I will be installing the rancho Quick lift next week and will show some before and after photos. I had the same lift on my 2011 and was very pleased with the ride and handling and the Quality of the product.

Do yourself a favor and just get a current 6.2. The new trucks won't be out for another 18 months and you're probably not going to want to buy a few year or two of an all new vehicle/engine combo. I won't. I figure that my '11 should be ready for replacement just about the time that the CK2XX's are all debugged. Kind of like how my '11 currently is. :cheers:

      2026 DENALI 6.2L

      By pyoung62 · Posted

      I agree with Tim.  As tech heavy as engines are these days, no way I’d be an early buyer of the new 6.6.  Of course, I bought my ‘26 Denali w/the 6.2 after dumping my Tundra with it’s defective 3.5 liter imploding engine disaster, so I’m a little gun-shy.  That said, my 6.2 has been rock solid.  I don’t drive it like I do my BMW Z4 M40i, but I don’t baby it either.  I got a V8 for a reason.  But I’m averaging 18 around town and 22 highway.  I have seen 24 highway as well when I wasn’t loaded up heavy.  Considering my Tundra with the twin turbo V6 only got 14.5 in town and 17 on the road, I’ll take the 6.2 all day, every day.  If I were you, I’d grab a ‘26 while you can.  Inventories are probably gonna start dropping and I’ll bet the deals will start looking sweeter as well.

      Can you add a 360° Cameras hard button to a 2021 Sierra?

      By ShowMeShooter1332 · Posted

      I am curious if anyone has figured out a way to add an hard button AUX or 360 Camera switch to the center row of switches. I have a 2021 AT4, and want to split the hill decent button and add a 360 camera button so that you don't have to go into the center display and locate the camera functionality, etc...   My father's 2024 Yukon XL AT4 and it has a hard button, see below. I found this thread on the Yukons, but it seems like there may not be a part number for the 2021 sierras. https://www.gm-trucks.com/forums/topic/255339-adding-hard-button-for-camera-on-2021/ Anyone else figured this out. Seems like it would need to be a custom switch!   I am getting ready to install the auto stop/start eliminator, so would be nice to knock them out at once.     Upvote1Downvote0Go to comments

      Oil Consumption

      By Chuck FB · Posted

      Through the years it hasn't been my typical method as I tried to drop oil on an engine that was hot from having been worked, however that was not always practical and had to fire up a unit and let it warm up reasonably well and drop the oil when I had the time to do it but am referring to not only vehicles but a variety of farm equipment and highway tractors etc. However on a vehicle where one is crawling under it and the exhaust is nearby to ones body and if wanting to pull the plug without danger of being hit with boiling hot oil or attempting to remove a HOT oil filter, its sure safer and easier to not have everything smoking hot and can remove the filter right away when under the vehicle and let it all drain. Of course its not the end of the world if a bit of oil stays in the engine that might have eventually found its way out, I like to get out as much as possible but any oil changes that take place in shops would rarely be sitting around for very long at all before the plug is thrown back in and filter slapped on and oil poured in and sent out the door quick like. There would be very little time spent ( assuming they even did it ) in starting the engine with oil to fill the filter, then waiting to verify the level on the stick. A good reason to check ones oil level shortly after a shop changed the oil on a vehicle just to make sure its correct and to look under for any oil around the drain plug or filter.
