Hi everyone, I'm pretty new to the LS-verse so be gentle 😂. As the title says, I've recently acquired an LM7 from an 01 Tahoe and I'm trying to throw it in the Colo, there are many helpful threads here for me to choose from but one of my biggest questions is what I should do about suspension? I...

Looking for advice, I have a 06 Colorado with the 2.8l rwd. I need to replace the bank 1 sensor 1 O2 sensor. Also my catalytic converter (from the manifold) has separated from the lower weld. I am really hoping to use this as an advantage and gut the cat while it is already exposed then just...

Hello all, I've been hearing some talk about the GM LH8-9 V8 engines that were released with the 2009 Colorados. I am currently driving a Base model 2006 Colorado 2.8L 4 cylinder and cannot help but wonder.. What would it take to swap the 4 cylinder out for the LH8 5.2L V8? Is it even possible...

I have been looking to get som LED tail lights for my 08. I like the style of these two but can’t find any pictures of it on the truck itself. Anyone seen either of these on a truck or have them on their truck? Any comments on if they fit/function well? Also concerned the smoked ones might be...

I just recently bought a 5.3l v8 and I’m just wondering what to expect to buy for it. Could the current wiring harness on it convert with it? What other parts may I need to swap out with it? Could the current tranny be fine with running with the 5.3l for a few months before I buy a new tranny...

I was driving up to the mountain this morning and all of a sudden my engine began revving up, pulled over, shut the truck off, took a look couldn't figure it out, so I tried turning on the truck and it made a whining noise. Then towed it home, took out the starter, had it tested and it was bad...

https://youtu.be/7vumZl9sdmU So this isn't my video but I have a similar issue It turns off when I slow down or stop. I have to place it in park to start it. When I'm flying through the HW it drives perfect. I was guessing dirty throttle body and I hope that's it. But if I remove the TB will I...

[For Sale] I finally took the time to roll out the Colorado, have it cleaned up, took it to the park and got some pictures taken. With the rain we've had here in the last 6 months, it's a feat to have it clean and be able to take some decent pics before it rains again! I've been looking for a...

Good morning from New Market, AL! I have been looking around 355Nation for a a little while, and I like it. I have a 2006 Colorado Crew cab that I got last year with about 81000 mi. on it.

I was dismayed to find out my 2018 Colorado with towing package didn't include proportional braking control for towed vehicles. (Thanks a lot GM marketing geniuses.) The indicated place on the dash left of steering column, and hidden behind steering wheel has a blank cover where the control(s)...
