I put one in the bottom of the grill. It has a DRL feature so I wired it into my ignition for DRL then tied it into my high beams to turn the hole bar on.

These are the best I've seen.  This is custom work done by shoreline motoring .

Schmidty, I thought the AT4's had a 2" lift as well because that's what a guy locally told me, but according to a few different threads on this forum, thats not true. Only the 1500 AT4's have a 2" lif

Has anyone seen any light bar, nudge bar, etc for 2020 Sierra HDs yet?  Anyone seen a nice behind grille setup?

following this! would love to see some hidden light bars with stock grills and bumpers.

yeah it looks like it’s got a lot of upgrades. 

 

it has 20” fuel wheels on 37” tires.

 

id love to get a close look at the trimming on this! the AT4s have a 2” lift from the factory so if they lifted it further, makes sense to fit 37s under a 4.5” lift.

 

the lightbars are badass - but again, the AT4 has a better grill for them!

I'm doing 37's on my AT4 but I think i'm gonna run my stock wheels. I just can't find any wheels that I LOVE, and if I do find something I really like, they are $1000-$2000 per wheel.

Interesting!  What is the difference in the suspensions between the 2500 HD AT4s and Denali's then?

 

This is a post that I also read that info: https://www.customwheeloffset.com/wheel-offset-gallery/1272819/2020-gmc-sierra-2500-hd-fuel-blitz-stock-stock

I believe it's a huge misconception that the 2500 AT4's have the same setup as the 1500's. To my knowledge, the 2500 Denali and 2500 AT4 are the same. I think the main difference is the AT4 would be for the people that hate all the chrome. My AT4 has every option that the Denali beside it had

very very interesting and i think that clears it up!

 

i think what we are learning is different installs yield different results from truck to truck. one truck might not have an issue with rubbing or clearance while the next, with the exact same setup, may have some issues. it’s wild!

Exactly! I learned that first hand when I modded my 2014 Sierra, sold it for a decent profit and then bought another 2014 Sierra and did the same mods but the second one had clearance issues. It's weird

That's awesome! Thanks for sharing!

 

Would love to see more photos of it at night and on during the day!

 

Also, you have any more pictures/insight as to how you specifically wired it up? i would love to do something like this... but would have to figure out how to get the grill off first....

      HELP! DUMPING COOLANT

      By SwitchBladeSierra · Posted

      If anyone lands here looking for an update - the problem wasnt with the hose, the clamp, etc... I purchased a metal Thermostat housing that just must not of been made to spec. It just wouldn't plug up the hose.. Went back to a plastic cheap housing - leak fixed. Some plumbers tape carefully placed in tandem with a clamp likely would've gotten the job done.   Best,

      AUX switch install

      For anyone following, this is what I have deduced from this forum - and my very specific niche case. Please do let me know if you see me going in the wrong direction here. For context, I have a 16 sierra 1500 w/t. Has TC and Cargo light switches. Removed the switch to find the X1 and X2 of the S48A connection populated with wires (x1 10-14, and x2 1-5).   Took photos of the X61A-X5 to find the wires from S48A-X1 land here at their respective pins (10, 11, 17, 23 on the X5). Was hopeful that this means my X51A fuse box has the appropriate pins... No cigar. So now I will be routing wires from the rear of the X61A-X1 to the engine bay and to their respective negative relay triggers. Please see to the diagram. If any has insight as to where the S48A-X2 pins 4 and 5 land that would be awesome.   Note: please disregard fuse sizes. Main fuse will like be 25A, all mini bus fuses will likely be 10-15A   Cheers

      287,500 Mile Service   8/13/2026   Reset Fuel Trims   Since the work done in the previous post there was a good improvement in response in all areas except right after a fill up where the LTFT would go -20%+ for about four miles while the STFT was near neutral. Before the work they both went very negative for a few miles after a fill up but act normal thereafter.    We did a systems check of the vapor recovery system for functionality and ability to hold a vacuum. That checked out fine. But this doesn't mean the charcoal canister is dead in the water. Testing that is next up. For now the reset of the fuel trims.    I intentionally shorted the fill exactly two gallons to eliminate any chance of filling the canister. On start up the trims were behaving normally until I got up and rolling where the LTFT went -10 / -11%% but the short was + 2 to 0%. Within a mile the the STFT offset the LTFT and by 2 miles they were neutral. HUGE improvement but still not hunky-dory.    I'll watch them for a few days. Perhaps another tank where I will fill completely to 'first click' and compare. Meanwhile on the hunt for a new canister and I'll toss another purge value at it for good measure. Pending the outcome of the canister test that is. Progress of any kind is welcome.    Fuel economy improvement with bringing hole #3 back to the living was a noticeable bump to the positive. Even on the few miles I drove after the refill I already see another bump up by the trims reset.     She's purring like a kitten with a warm bowl of milk.    BTW, adding 50 rpm to the idle took the majority of the negative timing out on cold start up and leaned the cold idle. No longer burbles in the cat. What a dumb way to heat a cat.

      Yeah, shame I can’t really get that filter easily anymore. Running a PureOne. Your fave!    TAN would be neat to see. Confirmation I ran it too long probably. 🤣

      Roll up bed cover experiences

      By superdave160 · Posted

      My son and I both bought new trucks in 2017. Both of us immediately put Truck Covers USA American Roll Covers on our trucks. My son still has his truck and it never sees the inside of a garage. We live in Alabama, so not much snow. My truck was my daily driver and was in the garage when I wasn't driving it or at work. No issues with either cover even after almost 9 years. About a year ago I sold my truck to my brother and bought a 2025 Silverado 2500. The second thing that I put on that truck was a new Truck Covers USA cover. They are very well made and have a very positive locking system. I looked at a Retrax and my concern was the way that the cover locked to the rail. BTW, the first thing I put on the new truck was step bars. Those new trucks are high!
