Did the Trifecta tune on my 2021. Seems like a good 1/2 way measure without needing to go an do a super... This thing rips now!

I've got a 2019 ZR2 Duramax. I put a retrax mx pro tonneau cover on with a 12" RCI bed rack with the tonneau bed rack compatibility mounts. The system worked much better than I expect and fitment was darn near perfect. I was also able to "carefully" drill into the bed rails and bolt the bed rack to the truck for extra stability. I wanted a metal retractable locking tonneau cover for the weather/bear proofing but also because I wanted to also leave a bunch of expensive gear in the back knowing it would be extremely difficult to break into. I lose a little bit of volume and depth in the bed but I also have the ability to put stuff on top of the tonneau cover and strap it down still. I went with the Thule ruggedized kukenam 3 tent and find it very simple to setup and take down. Got the tent 20% off from REI with first time membership discount. Got the annex "used" for $160 on amazon, in perfect condition. I also put the Valhalla off road research steel molle panels inside the bed to mount my mini shovels, hatchet, Co2 tank, diesel and water rotopax and a fire extinguisher. Mounting all the gear keeps the bed clear and stops the tanks from bouncing around in the bed while going fast off road. I can still fit a 40" long x 20" high cooler in the bed and still have room for any extra gear thanks to the Valhalla panels utilizing the space above and round the wheel wells became more appreciate after I had done it. I spent a lot of time planning out the mounting options but afterwards everything I had fit perfectly. I should make a video tbh...

Man nice job with the video. You’ll gain traction on KZfaq. Just keep making good content 👍🏻

Nice looking truck. I have the Relentless Fab swingarm bumper on mine, I highly reccomend it.

I have looked into putting a supercharger on my ZR2 also. I would like the additional power and like you I spend a lot of time off-roading at a high elevation. I have noticed a decent amount of power loss with the naturally aspirated engine and understand forced induction would take care of a lot of that. With that said I can do a lot of other mods for the $12k I would have to spend.

Sweet rig man. The super charger catches my eye too but it's expensive and seems like a huge task to put it on. Best of luck with future mods

I went with the 4.56 gears and trifecta tune. It's the best thing I've done to the truck and my transmission thanks me lol

I’m going to buy a camper top soon. Liking the canopy style

Upgrade really are so much money. I’ve been looking at different options to put 35s on my 2018 ZR2 Duramax. But like you said, with the re-gearing and everything it’s easily over $5000 plus another $2500 for wheel and tire. But I think a solid front bumper with a winch would be a better upgrade but that’s still another $3000+. But I’m also really interested in the snorkel for intake protection and I also really like the skid plates AEV made for the bison. Again, $$$$$. Lol so many upgrades, so little money. Also like you said, if I just made more money hahaha. Your truck looks really good. I was looking at the rooftop tent, but went with a 25’ trailer instead. I freaking love the trailer, super nice to use as a base camp for off road adventures and the truck does pretty well with it. Good luck

Sweet mods. I have the exact same year/color ZR2 and needed some inspiration. Based in Loveland. Thanks

Beautiful truck!

Check out Relentless fab. They make a great steel bumper with the swing out tire carrier. I just got the regular rear bumper because I didn’t want to spend the extra money at the time for the carrier. Big Mistake!! You can’t add it later. I should have got it now the spare is in the bed. I got the 4.10 gears probably the best mod I have done but Definitely get the 4.56 since you have 35’s. Trifecta tune is great also.

Your truck is looking good. If your going to keep 35s I would go with the 4.10 gears. If you look at the AEV factory trucks they are geared to 4.10 for 35s. Im in the process of doing the same thing. I think AEV put a lot of time and research into choosing the right gears for their trucks. Good luck...

Thanks for showing.

Nice review Brother and the truck looks great. Where you buy the fender sides ? I own 2018 duramax zr2

Nice. Good job. Like it!

I just checked the Victory4x4 bumper is capable of adding the swing arm for a tire and another for water/fuel cans. It shows it on the site. It is designed specifically for the Tacoma, but many mods for the Tacoma can fit the Colorado. As far as the Bison bumper for the Colorado I’m not sure if you can put a swing arm on it. Maybe after market.

Such an effective build. How much did your mpgs change after putting the 35s? I might want to do the same, I'm debating between your set up or the 33x11.5.

Hell yeah, thanks man!!

Love 2019 got 37 inch tires

Gears and a tune...do that and you may decide you don't need a supercharger anymore. Also, relocate those rear shocks!

Nice truck! I have a Colorado ZR2 V6 but a 2017. I like your upgrades and they do get expensive. I was also thinking of getting a supercharger too but the cost...If I do is it worth it? Does it add value? and I guess your warranty is out the window... Also how about roof racks?? What do you think???

Nice truck !

Cannyou tell more about your cover for the bed I have a CBI rack with rooftop bed but thinking about a cover for the bed like yours the name please of the cover? Thank good information I have the diesel 2020

I’m planning on going 35’s too, how is your front diff handling it when you put it in 4x4? Been reading the trans and front diff go first on 35’s

all the mods look fantastic

Nice set up. Did you go with the gas or diesel version?

Looks good

Back in the day we used to call those type flares cutouts.

This is stock?? Or is there an additional lift on the stuck, I just got a 22. idk how Id be able to put 35s on it without additional lift

Where do I find one of those front license plate brackets? I've been in contact with dealerships, and they don't even have the part listed in their systems. I need one, but have had no luck finding one...

Did you get the Colorado specific bars or the universal set that CBI sells?

Awesome. I envy you have ZR2!! We only have Z71 in Korea

Nice set up. Did you do bump stops ? If so which ones ??

Man zr2 power babe just my shorts out on my zr2 I got the same year but I lifted my on 35s I want to do the aev flares too .... your front one does not look right to me ? Having that gap from the bumper is not normal from what I have seen with other people's flares installed

shoulda got the roofnest brah it pops up and closes down in a minute

How does it daily drive without regearing?

how’s the truck holding up at this point?

Any “shudder” issues?

Would you be willing to sell that spare?

would you like to get a free light bar ?

Do you have an Instagram? I have a ZR2 also and wouldn’t mind following on here too.

Yeah, deal with that spare tire issue first for safety sake.

Luck good on 35 tire

Love the truck and your videos. Wanted to know how your reliability has been. I'm wanting to get 1! Thanks!
