What Did You Do To Your Truck Today? v2.0

[daddy]

I will look at this recipe, I definitely want to do it right. The AT4 does not have as much rake, so hopefully I can find the right combo.

I am intrigued by the longer axle, for sure!

I am sticking with 18s this time...I swear!

I can send you part numbers. The Eibach’s are very adjustable (threaded, not snap rings) so you can dial it in just like you like.

The shafts aren’t necessary, but I wanted to do it as well as I could.

There is another device that easily attaches to the battery and alternator harness. I learned about it on the AT4 Forum.

To be clear, do you have the same switch that I do in the dash?

Different location, but yeah.

Suuuure!

Man, 12 years of 20 inch 10 ply tires at 80 PSI have done me in. My spleen can no longer take it

These 18s ride so nice. The wife and I took a run up a backroad this morning in North Idaho, she instinctively grabbed the Oh Shit handle when she spied the potholes i was about to roll through at 70, but soon realized how nice this thing soaks up bumps.

Colorado lift blocks?

Mine already has the 2" in the rear. AT4 and TrailBoss have this, apparently

Tobias, the AT4 needs the 1.75" UCA Kit to level, which gives it 3.5" over a "regular" suspension truck. I already have the axles you mentioned in the AT4 package.

2019-2024 GMC AT4 And Chevy Trail Boss - 1.75'' Leveling Kit

1.75" front leveling lift for 2019-2024 GM AT4 and Trail Boss Not compatible with Sierra AT4X or Silverado ZR2 Edition. Includes DOM tube steel upper control arms with TCT maintenance-free pivot bushings and 1-ton ball joints CNC machined aircraft-grade billet aluminum top and bottom strut...

That will get me 285/75R18 without trimming

Something odd with Amazon, I guess.

My account shows that part number as what I ordered but that isn’t what I ordered. Oh well, you don’t need it anyway.

It is. I was installing an airbag/compressor setup. I’ve always used AirLift but he decided to go with Firestone.

Don’t ever go with Firestone.

There stuff is well made and it’ll live a long life but it was a giant PITA to install. The Wireless One from AirLift has u-bolts that mount the compressor and solenoid (all one unit) right on the side of the frame rail.

The Firestones were separate units and I had to build a base and mount out of aluminum bar stock, mount the Devi es to that, then mount the entire thing on the bed’s cross braces using the heat shield bolts. Way too much work for no good reason.

Just an FYI for anyone thinking about it.

That does sound like it was a pita to install.

Yeah, I've had to adjust to 65 psi with the RAM.
