Ordered Christmas present for the 2003 Z71 Tahoe (she deserves it)….

Coil-over kit from Atomic Fabrication and matching rear shocks…. been on the “wish list” for a long time.
I just completed the front mod a few months ago. Have not done the rear yet. Absolutely love it.

Nah, just a cheap cover indeed on. It’s flaking after 4 years. Could t find a good one. The one I installed on her Altima was REALLY nice. This one sucks
Kind of looked like the Grant wheel. I've heard its been discontinued unfortunately.

Thanks for the information…
Any issues with the installation? / items to be on the lookout for?

I finally flushed the brake fluid out with the help of one of those suction tank things. I think I bought it nearly two years ago to do this job and procrastinated that much on it, yikes! But that suction tool has been very handy. I also used it this time last year to drain the trans 6 or 7 times as an easier method to swap out the the trans fluid.

I depressed the brake pedal a few times when flow became stopped....I had the passing thought while I did it that going to the floor might not be the best idea. On startup "service brake" showed up but pedal feel was fine, actually a good bit better than before flush so I wasn't that worried. Checked for leaks, plugged HP Tuners to scan for codes...nothing.

I removed the negative cable before bed and all was fine this morning. Whew!

Not really, but my setup is for a 2wd 2002 Tahoe. If you watch the videos on the Atomic website, he provides all the guidance required. I do have two comments though. On the the drivers side upper support bracket - ensure you install the upper hardware (bolt and nut) first. Second, In order to get my ride height correct, i needed to adjust (raise) the preload (lower two lock rings) almost an inch. I did take a few pictures on my build thread. Atomic's customer service is awesome. Feel free to reach out to him - he will respond very quickly.

Thanks for the 1st hand run down.
I have watched some of the videos as well.

Took a pleasure ride in it this morning, at least it was that until I got to the office. :(

Topped off the tank with corn fuel on the way home, almost 15 gallons @ $2.50. Premium (91 here at altitude) is only 50 cents more now ($3), so it's almost a wash. But I stuck with the E85 for now.

Well, I bench bled the master cylinder the other day, got all the air bubbles out. Installed it today--wasn't able to bleed the brakes yet--but the damn pedal still goes to the floor, and it barely stops. Same exact thing it did before changing the mc. Gonna bleed them tomorrow. I really hope that'll finally fix it. Anyone have any ideas? It's not leaking at any of the 4 calipers--or anywhere else that i can see. Everything is dry.

Finish bleeding the brakes then see where you are.

Hi guys, hope everyone’s been doing well. I’ve been away for a few years.

Still have my 2007 GMC Yukon

The beast pulled my 20 foot enclosed trailer 2500 miles from Seattle Washington to Dayton Ohio

I installed an equalizer weight distribution hitch on the trailer with the real nice heavy duty ball Mount hooking it to my truck

I also had a local shop in Seattle installed an auxiliary transmission cooler, which I’m sure really really helped coming over those three mountain passes where my transmission temperature would’ve definitely overheated without it

I’m curious about LED headlight lamp replacements for my 2007 Yukon

I’m wanting to replace all of the bulbs in the headlight assembly with LEDs so that I don’t have to ever mess around with changing them again probably for the life of my vehicle

I’m sure you guys know the best brands where to buy them which ones to stay away from which is why I’m dropping in besides saying hi hello and answer any questions on my trip and how my rig handled pulling that trailer across the country

Happy holidays, everyone
