Sorry to disagree, but I have personally done that change albeit on a much heavier chassis. Ford Motorhome actually. So many RV owners do it there’s even an acronym. CHF or the ”Cheap Handling Fix”. I will certainly agree there’s a wee difference between the vehicles. ;)
In that case it was noticeable to my passengers as well.

On the other hand, some claim handling benefits using poly bushings rather than rubber; seems like a minor difference in dimensional compression to me, but I have no experience.

I suppose it all depends on how sensitive an individual driver is to vehicle dynamics.
Yes, it would certainly be a sensitivity thing. :)

Actually maybe I could buy the notion that moving the pickup point inboard a few inches on an otherwise stiff enough bar making a difference in perceived body roll, especially on very tall vehicles.

As far as that kind of change having an impact on understeer or oversteer and corner handling in general, a few inches on the same bar? Not even close.

On a few of my early race cars we had bars that could be adjusted as much as 18”. The difference between full hard and full soft on one end was always a tweak, never anything that was going to change an under or over steering car back to neutral.

So do I think the few inches of adjustment on the bar in question would make a noticeable difference in perceived roll stiffness on one of these trucks. I am afraid it would stay in the placebo category for my opinion. I guarantee you it would not change a lap time on any road course I have ever driven on.

Got the new water pump and rad hoses on, fabbed up a surge tank restrictor for the Cold Case and new upstream oxygen sensors.
Just need to double check tire pressures and give it a wash and I should be ready for my trip tomorrow. Hopefully I don't get any other surprises at least until I get back. Haha

My 9yr old wanted to do the head lights. I just supervised. Respect to everybody who puts a YouTube video worth watching. That’s how he learned how to do it. The Denali is new to us

I had a smh moment with theothertwin today. I monkeying around under hood to check the AC condensate drain, and just happened to notice something at the fuse panel.

First pic is thecopcar. Second is theothertwin.

When I first got theothertwin, the main battery had 5 dead cells. I drove it on the auxiliary battery only for 3 months. knowing thecopcar has the batteries in parallel made me think nothing about it.

The difference in the two pics is the battery isolation relay is installed. But it’s been bypassed. All of the cables are attached to the upper terminal only.
