I'm not sure I follow you on that last comment. When the KO2s were new and hit a large puddle on the side of the road, they cut through it like butter, no steering wheel jerk in up to 3-4 inches of water. Similarly, when we hit a torrential rain storm once, there was 2 inches of standing water on the road and the truck did not flinch hitting that at 80 mph and maintaining that speed until traffic forced us to slow down. Pretty amazing to me. I was thoroughly impressed with my BFG Radial T/As when the new tread pattern first came out in the early 1990s and these are similar but even better.
extra Weight collection on the front this was "wet snow" at lest 40pounds collected under the bumper
it has the nivomat shocks (ZW7)
lol, 225lbs on the front bumper would not even make the rear bumper budge, ask me how I know
CUZ whens I stands on it it don't change noneOkay you got me, how?

That is looking damn nice!
I played with HPTuners today. Got some burbles now! I have it set so that below 0.2 grams of cylinder airmass between 2,000 and 4,800 rpm, it will drop the timing to 8* before top dead center. It won’t do it on deceleration because it opens the throttle too much, but reving the engine in P or N, it will sound like this.

Texas Speed Low Lift Stage 2! IIRC 212 intake duration, 218 exhaust, 0.550 lift on both lobes and 113 lobe separation? I have a pic of the cam card around here somewhere.
Nice burble, mine does that on decel if I downshift. Hey look at the dash now, it’s nearly complete.

Holy fork that matches REALLY well. I didn’t realize how close the silver trim was to the esky cluster. Almost makes me want to do the esky swap in addition to the silver trim. Main reason I won’t do the esky cluster is because it doesn’t have an oil pressure gauge. I know you can put the oil pressure on the DIC but that’s where I like the trans temp to be
Esky cluster sweep.

Okay thats pretty cool.
LOL at the ‘service suspension system’. The air bags and tube frames Im sure piss the autolevel computer off
Most of that trim I wrapped although I did decide to go ahead and buy the brushed pieces off EBay as they become available for reasonable prices.

looks like someone used Non Nivomat struts with the factory Nivomat springs(ZW7)
can you believe the max payload is 1700-1,830 lbs LOL surely with 1800pounds you would not even move due to the drag of the wheel wells
for some reason the rear has it's butt up on the air on my suv i'm sure this has something to do with the cold as it was lower in the summer..
on my tahoe (nivomat struts)
GM was super nice and they are giving them away at cost price
$61 for ZW7 struts
PREMIUM SMOOTH RIDE CHAS PKG(ZW7)
they will not work on the ZW7 for the regular height unless you get the factory (lowering kit)
Aftermarket spindles and struts in the front for a ~3" drop and coils from a Jeep Wrangler in the rear for a ~4" drop. Deleted Autoride and (for now) ALC. It did as expected with a 3/4 drop, fat tires and the weight of the cargo.
I've been letting it rub while I drive it how I want so I'll know where I need to modify for clearance.
and? that doesn't explain how 40lbs of weight on the front is going to lift the rear 2" not gonna happen buddy
I call BS that 40# of snow caused either the front to drop 2” or the rear to raise 2”. If that were the case, we’d be damn near flipping cars on their noses here in the Midwest with all the snow that gets built up on the front bumpers.
Wait...it’s gotta be true, Brent said so.
