The Chassis Unlimited isn’t stealth, but it’s not bad. I’d really like something similar to what Ford does, just the fairleads/hook visible.

I’d think they would put a “roof” above the wires and switch. I just can’t imagine a design that would cost them money in warranty repairs.

Has anyone actually opened up the tailgate to see if those holes allow water to hit the electricals? Seems like such a poor design that I question whether it’s true.

Haven’t been able to find one for sale. Wish they offered one like Ford does.

3 of my last 4 2021-2022 GMC 1500/2500 have leaked. Most recent is my 2500 which is leaking three weeks after taking ownership. Build date was 7/22. It may not effect every truck, but it effects a bunch. The dealerships here are very well aware of the problem.

My 2022 2500 AT4, built 7 July 2022, is leaking slightly (rear window, driver side).

I actually found out about Elkas through a Tacoma forum. A self-proclaimed Kings fan-boy and dealer gave them rave reviews. After reading their website, I saw a lot of words that described my own needs and was kind of shocked (haha) I’ve never seen them mentioned before, even in conversations where people mention having these exact needs (that is, a mix of on-road driving as well forest/fire roads, washboards, etc). They seem almost too good to be true. btw, I think they have a set that’s for non-lifted trucks, too.

I’d love for the mirrors to either auto-unfold upon approach, or upon unlocking, like my wife’s VW Atlas. They fold when you lock, unfold when you unlock. They double as a lock indicator for those times your home and want to check your car doors.

After much suspension research, I’ve landed on Elka 2.5 Reservoir coilovers and rears for my AT4 6.2. I chose Elkas because they’re progressive valved and I’m told that’s best for my needs (on-road as well as forest roads w/ washboards, potholes, etc.) Before I pull the trigger, does anyone have any direct experience with these on a Sierra or Silverado 1500? https://www.elkasuspension.com/product/2-5-reservoir-front-rear-shocks-kit-for-chevrolet-silverado-1500-2019-to-2020-2-in-to-3-in-lift/?c=72e1ba2726d6 After all the positive reviews/info I’ve read about them online, I’m kind of surprised they’re not more popular. They seem to fill a niche in that they’re an improvement over stock without being too firm for daily driving. Any info is much appreciated.

If someone’s getting flashed enough that feel compelled to make a forum post about it, they probably need to adjust their lights. It’s worth investigating at the very least. None of us can say for sure, but since he asked for advice, people gave him advice.

I’ve never been flashed in my AT4. When I flash others on the road it’s not to be a dick, but to let them know their high beams are on and blinding me. I’ll never understand why people get so offended when someone flashes them. If multiple people flash you, maybe get your headlights adjusted.

Looking forward to your report.

Who’s running this kit on their AT4? What are your thoughts? Tried searching, but not many results. https://cognitomotorsports.com/cognito-1-inch-performance-leveling-kit-with-fox-ps-coilover-2.0-ifp-shocks-for-19-21-silverado-trail-boss-sierra-at4-1500-4wd.html

Thanks, Dunn. I’ve asked them if it works, but haven’t received a response.

I didn’t think sport/tow mode disabled Start/Stop on the 19-21? You can turn that feature off with the press of a button.

Thanks everyone. I guess my next question is which aftermarket UCA will allow me to keep my OEM 18” wheels? A few kits I’ve picked claim to be incompatible with OEM 18” wheels, and I’m told it’s due to the UCAs. I’m leaning toward these RC UCAs that will let me lift the front 1 inch over stock for a total of 3”: https://www.roughcountry.com/gm-forged-aluminum-upper-control-arms-29501.html?find=2021-gmc-sierra-1500-4wd-752716#overview

I’ve actually put out feelers in the Portland area, but maybe I’ll find a shop that can demonstrate the difference. When I say off-road, I’m mostly talking about bad gravel roads and forest roads, so nothing major. I’d like to be able to go 20-30 mph since some of these roads are very long and going 5-10 mph can add hours and hours to a trip.

Thanks, Gangly. After seeing many of your responses elsewhere, I value your feedback since you seem levelheaded and reasonable. That, and I’ve read enough good feedback about the Bilstein’s that I think they’re what I need.

Thanks, also want to be able to hit rough/washed out forest roads without rattling family’s teeth. These are a third option I like, but no compression adjustment: https://www.bilsteinlifts.com/shop/chevy-gmc/silverado-1500/2019/cognito-1-inch-performance-uniball-leveling-kit-with-fox-ps-coilover-2-0-ifp-for-19-20-silverado-sierra-1500-at4-silverado-1500-trail-boss-4wd/

Hi folks, I have a 6.2L AT4 and as much as I love the truck, the shocks are a little too bouncy. I’ve spent hours researching suspension upgrades and I’ve landed on two options: Bilstein 6112/5160; or Fox 2.5 Performance DSC. Both with upgraded UCAs. My goals are less roll during turns, less bounce on the highway, more compliance with the road/pot holes, and good washboard performance. Good on-road performance (not Cadillac-like ride, but at least not jarring) is also important. I don’t do serious Baja style off-road, but many local forest roads are rough. I’ve read mixed reports about the Bilstein: some say they’re perfect on and off road, and some say they’re too firm for daily driving. The price is what has me considering them. For anyone who owns these, will they meet my needs? I’m considering the Fox 2.5 DSCs because I understand I can change the speed compression, and I’m guessing that means I can firm them up for off-roading, or soften them up for daily driving. Am I right?

You know people were successful? Any sources?

Yeah, that’s actually why I chose 275/70R18. I didn’t want to risk any rub down the road. Probably could’ve gotten away with 295/70R18, but I’m happy with what I got. Next purchase will probably be some 20” takeoffs with slightly larger KO2s or Toto MTs when the time comes.

If the engineers who built the truck advise a break-in period, then why not? What harm will it cause for anyone to not eat their engine for the first 500 miles? Especially considering what the truck costs. Seems like a no-brained. What may have worked in the past for other types of cars may not work today. These vehicles are so different from cars of the past that it’s an apples-to-oranges comparison. Edit: I’ll add, with the reports of lifter failure and oil consumption, why not do what the company recommends?

I may be experiencing what you’re describing. I’m not that mechanically inclined nor have I ever driven a 6.2L, but it does feel a little rough/awkward when I stop. I may disconnect the pulsar later and see if that solves the problem.

Great post! Thanks for taking the time to share your decision making process. I’m thinking of doing something similar as I research tires for my 18” wheels. I’m curious why you opted for the 275/65 over 285/65 KO2s. Was it weight, or size?
