This thread has been a long time in the making, but here goes! As promised in my intro thread :)
https://www.355nation.net/forum/new-member-introductions/182698-new-guy-2005-z71-4wd-5mt.html

Back in March of 2016, I finally got a truck. It came up after buying the house, and I got a deal.
The truck itself is a 2005 Chevy Colorado Standard Cab Z85 4x4 with the 5 speed manual transmission. It had 194K on the clock at the time, almost 199K now.
Completely bare bones, the only features it had were auto headlights, Z85, and 4WD.

Issues with the truck at the time I bought it:
- Headlights and tail lights needed replacing
- Fuel cap message (P0455)
- Front/rear bumper were a bit banged up
- Seat was halfway worn out, was the fixed bench (no arm rest)
- Tint is crap
- Toolbox had no key, so I couldn't lock it

Mods I have done so far:
- Replaced the clock spring to add cruise, unknowingly the turn signal was almost worn out as well.

Planning a trip to Uwharrie later this month, we'll see how that goes!!

I'll continue to update this thread with more info as I progress, there's some nice LED tail lights here ready for install along side my SuperSparkz :bestest:

Other planned (future to way future) mods include a mild lift to fit some 31" AT's, maybe a new radio to get HD.

Re: [Progress Log] ATMINSIDE's 2005 Z71 4x4

A few updates today, we'll start with the small stuff.

SuperSparkz were put in a few nights ago, along with new coil packs. It made all the difference in the world with how the truck runs! Noticeably peppier and smoother (even to the GF).

The truck also has a bed full of a bradford pear I just took down right now.
Plan was to go camping in Uwharrie this weekend and have firewood, but unfortunately that isn't happening now.



More notably, I've learned the Z71 stickers on the truck are, in fact, fake.
Saw a few things odd as I've dug into more mod research, and it is indeed a Z85. Updating the first post and such to reflect this.

A set of Z71 flares will fit a Z85 and I believe about 1" of lift (maybe not even needed?) will fit 31s.

Lift shouldn't be needed at all to fit 31's. The height difference from Z85 -> Z71 came from the difference in tires.

I was already working on a lift anyway, then getting bigger tires. Now I've changed to planning for wheels as well due to the difference in width of the wheels from Z71 -> Z85.

Alright, so I know I have this for future reference I'm dropping all my RPO codes here.


Also, some goodies showed up last night!! Just need to get the lift parts in-house and it'll all get installed at once.

In for updates, and more importantly, good choice of beer! :drinking28:

I'll be sure to include more beers in the pics of wheeling and work then!!
:drunk:

Don't have pics of them, but the Tuff Country AAL's showed up yesterday. Thanks @RednecKevin for the deal :)
They showed up yesterday?! Holy shit that's 3 days ahead of tracking. Good deal! Damn shipping was insane on those and I only made 10$ on them in the end but I'm happy to get them out of the garage and glad to see them put to use finally! Can't wait to follow the build. Thanks again

Yeah, yesterday! The shipping was super fast :) I figured after how long you'd been sitting on them you'd be ready to just get them gone.

As soon as I can get three things I'll be starting the work; a taller jack (hopefully tomorrow, there's a sale at Northern Tool for one that goes up to over 21"), the front key kit from SuspensionMaxx, and TIME.
Last one is the tough part... computer part reviews have me super busy right now.

Considering wheel/tire packages, really liking the 16x8 Mickey Thompson Classic III 4.5" BS with a solid 265/75-16 AT wrapping them.

Got the new tail lights in tonight!!


Old vs new, just to show how bad they were.

Finally got around to doing some work on the truck this weekend. Front shocks are done, had to stop and work on the girlfriend's car before I could get to the rears.

Driver's side came off nice and easy, passenger's side not so much.
Basically 199,440 miles on it as of this work :)

Front of the truck feels amazing now, the old shocks were SHOT for sure.

Used the Skyjacker Black Max Shocks, part number B8540. Grabbed the set for the whole truck for right at $160!

Driver's side installed:


Shielding the brake line on the passenger's side:


Removing the stud from the passenger's side:


And the victim (passenger's side shock):

Also, while I had the truck in the garage, I took the hub to fender measurements.

RF - 22"
LF - 21.75"
RR - 21"
LR - 21"

Do those look normal to you guys or is it sagged out?
Okay, finally got to do more searching while I'm recovering from surgery to remove my wisdom teeth. Looks like stock should be 21" front and 22" rear so it isn't sagged THAT bad in the back.
Doing the AAL and SMaxx kit for the front should be perfect.
Quick update, no pictures from this weekend unfortunately.

First, the bad. Rear leafs are definitely sagged beyond saving.

The good! Got the catback exhaust on (Walker OEM replacement), swapped the rear shocks, changed the fuel filter, replaced the MAP sensor, and replaced the PCV vent hose.

Also, I think I found where I was getting water ingress into the cab. Got the passenger floorboard dried out, left the seat out and propped up the carpet with a fan blowing under it for a night, and sealed up a floorboard hole (someone had drilled it).

The fuel filter was comically dirty... Literally looked like mud instead of gas pouring out. Guess it hadn't ever been changed in the 199,7xx miles on the truck.

Update time!!

We got about 5" of rain in three nights (two days), drove the truck both of those days, and no moisture in the floorboard!!

Also, last night was absolutely gorgeous out. So, what else would I do besides put on the Z71 flares I bought??
Definitely pleased with the look, they'll be a perfect fit once I get tires on that aren't 235 wide.

I stall can't get over how much fun your truck must be

4 banger, 4wd, 5 spd and 4.10s

Looks like you've done some solid maintenance..... BTW, we love all the pics :thumbup:

It's an absolute blast! Need to get it back out wheeling again, its been longer than it should have.
City/highway mix it gets about 20mpg right now too, with the price of 93 it's honestly cheaper to drive than my WRX... LOL!

Lots of maintenance has been needed, but I fully expected that I'd need to "play catch up" on a truck that was pushing 200K miles.

Next up, I need to get those C10 rear leafs and do a crank... then tires.
Took the toolbox off last night, should be putting on a roll-up tonneau tonight.

Will likely build a box for the bed unless I can snag a deal on something pre-built.
Need to figure out the tailgate lock though... the mechanism in it is missing.
Not sure if I need a new tailgate handle or a new lock assembly and then just reuse my cylinder.
