Goal of my upgrades was to have a better "stock" look, not void my factory warranty (still some risk), and actually have a truck that could go down a fairly rocky dirt road such as in a National Park.  Stock truck rode perfectly on pavement but off-road bounced so much that it felt like the truck was ripping itself, and me, apart at just 20 mph.  What I ended up doing is like what GM is now doing with their "Trail Boss" package (package has 2" lift, 33" tires, Off-road struts/shocks, skid plate, Eaton locker rear end--I think).  This forum was key to helping me and I want to give back and hope it helps others in any possible way.  Other site I used was "CustomOffsets.com" gallery--I tried posting these photos there recently but they no longer allow "stocker" truck postings.

 

Summary:  Bilstein 5100s front (highest setting) and rear.  Stock rear blocks.  Toyo MT Load Range "E" model (exactly 33 x 12.7 per Toyo site).  Stock GMC rims (18 x 8.5; +24mm offset; NO spacers). 

 

Bilsteins:  I got 1.5 inch lift in the front (others are reporting getting more than that).  It would look better to me with another 3/4" but I got what I got and don't want to add anything other than the Bilsteins due to my GM warranty concerns.  Bilsteins eliminate the body roll in turns, take bigger dips great, and have cut my dirt road driving bounce in half versus stock--they ride fine on highways at speed also.  Given the Toyo MTs have such deep tread and have some "tire squirm" in higher speed turns (ex: highway entrance ramp), the elimination of body roll with Bilsteins is very helpful to keep the truck "planted" so it doesn't feel like it will get away from you.  I also think the Bilsteins are better for the suspension because the Toyo MTs weigh twice as much as the stock tires and the Bilsteins handle that weight better. 

 

Toyo MTs:  I have not had any rub except for on the liner on the passenger side and it was only at full lock--one zip tie fixed that.  I have at least 1/2 inch clearance on sway bar and upper control arms in all directions at full lock and with the suspension "articulated" as in an off-road situation.  For you tire shoppers, I did NOT have to do any NorCal mod and do NOT have any rubbing, but if the tire diameter was any greater than 33", I would have had one point of contact on the driver side at full lock with suspension articulated--again, I have no rubbing with what I bought.  Each of these trucks seem to have slight build variations.  Some folks report using greater diameter tires but my truck would have an issue with any bigger diameter tire.  It is critical to look at the exact tire specs for each tire considered on the respective manufacturers website as well--one might be labeled 33 x 12.5 but only be 12" wide.  For looks, I wanted a "wide" tire also along with that aggressive and functional tread design (I do not tow and am never in snow) and sidewall puncture resistance.  Never had off-road tires before and was surprised at how fine the Toyo MT rides, even at 80 mph (I am a lifetime Michelin LTX guy before this as comparison).  Tires have triple ply sidewalls and the tread is beautiful but it does burn off quicker than you would like it to--you gotta pay to play.

looks really good, thanks for the write up!  I might make a suggestion since you are on rocky roads so much, add some mud guards...I have been really impressed with mine, was surprised how much road rash was spraying on my truck for as little of off roading I do...

So i put my RC 2" level kit and Toyo 295/55/20's on this weekend. Install was simple, just like on my 2011. It definitely helps to have an extra set of hands when wedging that spacer in there. 295/

Thanks. Here is one more from yesterday. Considering we're getting 8-10 inches of rain the next two days, I won't be taking any better pics soon.

I still have not diagnosed my "knock" noise since installing 2" front level.  I chose the "donut" style spacer that mounts to the shock upper. 

My noise is a single knock when traveling slow that sounds like something is shifting on the driver side when going from forward to reverse. 

I am beginning to think I possibly did not grind the factory bolts flush with the top of the new spacer and there may be a small gap that is allowing a forward / backward shift. 

My next plan is to completely take apart the driver side and start over.

Any opinions? 

I would probably bet money that its sway bar link related.  When weight gets shifted from one side to the other and a pop/knocking sound is heard typically just once, then that's my guess.  I had issues with my old truck doing the same.  When I got new tires and an alignment, it fixed the issue.  I would remove the sway bar and links and test to see if it makes the noise or not, then replace the links if that's the issue.

Thank you for your opinion! I believe you are on track. I had this hunch as well, and 2 days before my above post, I replaced the driver side link. 

 

I did not pay attention to the angle before the install, but it seems as if both links are in a forward angled position.  During install, I do not remember having a problem getting either link in or out, and this time I had to fight to get the bolt in and out.  I did not loosen the passenger link, as my noise seems to be coming from the driver side, but it appears to be in the same forward-angled position. 

The reason I posted a few days ago is since swapping the driver's side link is I still hear the same noise; however, it is less frequent.  I was hoping to have this resolved before installing the new tires and alignment - preventing the need for an additional alignment if having to work on the truck afterwards.

 

In conclusion, I have installed the level, and swapped the driver's side link only, which decreased the frequency, but did not solve my issue.  Do you suggest new tires with alignment, and then drive immediately home and swap both links?  Or should I swap the passenger link as well and get an alignment before installing the new tires?

Or possibly I should have the alignment done and ask them to check both sway bar end link angles while it is on the lift?  Maybe drive it for a week to ensure the noise is cured before installing new tires.

Thanks for the mud guard suggestion.  Since I have the "base" model truck, it didn't have rear wheel well liners so I added those already and now maybe I will add the mud flaps.

What wheel liners did you add?

      Oil for Supercars 'To Run Dry In A Month'

      I also found this.. API activated emergency provisional licensing because of base oil supply conditions meeting force majeure thresholds.   I wonder what's being substituted for Group III base oils...

      Oil Consumption

      By chris21 · Posted

      You seem to be struggling with reading comprehension.   I HAVE SAID 3 TIMES THAT THE BOTTOM OF THE CROSSHATCH IS A QUART BELOW FULL.    I have also said that the manual will not call that "1 quart low" because it is not a quart below the acceptable range in answer to asilverblazer saying that he has never seen the bottom of the marking noted as "1 quart low" in a manual. The wording of the manual allowing for an acceptable range would indicate that .00001" above the add mark is ok. Also, because the manual allows a range, a quart below full and a quart below acceptable are two different volumes. Thus the manual will not use the phrasing "1 quart low"

      injector cleaner 2021 2.7 1500 silverado

      By Grumpy Bear · Posted

      GDI Injector tips are in the combustion chamber and yes, they are subject to the same aromatic hydrocarbon based carbon build up the entire chamber is subjected to. Chevron Techron is a PEA based cleaner (polyether amine)  that is VERY effective if the dose is high enough.  Carbon the tips disrupts the spray pattern so keeping them clean is kind of a big deal. It will clean more than the injector tips. It will keep the inside of the injector tip clean as well. When they shut off they 'hot soak' building varnish internally behind the pintle. The tip, unlike most MFI systems have several orifices of very small diameter. They have to stay clean to work right. That spray pattern is supposed to spray into the cup in the piston, not all over the cylinder walls. Old guys will understand...    Top Tier Chevron has enough of the cleaner to be effective if used regularly. Other solutions could be Shell V Power Nitro + Premium and Exxon/Mobil Supreme Plus Premium ONLY use a different chemistry to the same effect with the added bonus of a friction/antiwear additive as well. Red Line SI-1 is PEA based as well with an upper cylinder lube. There's a white paper on their site for shock treatment of system left untreated for long periods. AMSOIL PI has a full system cleaner of yet another chemistry that will strip carbon out of the power cylinder pretty quick. Gumout Regane is also PEA based but at very low doses and those that are isopropanol based will not be effective. Alcohol content is way to low. Chevron Techron in any pump gas, Use by package instructions. 10 oz per 15 gallons every 3,000 miles. First use may require two treatments.    So, Techron, Red Line SI-1 and AMSOIL PI if batch treating and Shell, XOM Premium or any Chevron Fuel will not just keep it clean, but will clean it if dirty. No other fuel "I'm aware of will do that".    Flex Fuel motors. If you use at least 40% alcohol on a regular basis they won't carbon at all. PEA is not recommended for fuels over E-20     (www.carparts.com)

      4 Wheel Drive System

      By Another JR · Posted

      It is always a good idea to exercise it at least every few months to make sure the actuators don’t get stuck. It is also a good idea to actually drive it for at least a few hundred feet when you do that so seals experience motion and oil movement.  Off pavement or snow/ice is best for this, but driving wet pavement in a straight line for a  short distance will work if you don’t have other options. I have  forgotten and gone as long as six months between exercising it on my 2021 and it has always shifted promptly.  I usually just use my straight 300 foot gravel driveway.
