What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I agree, of all the mods I've done over the years, getting an alternator that will charge solid at idle is the best thing for drivability. not just motors, but the injectors themselves fire much more more stable at the correct voltage. there's a table in most ecm's for the voltage vs time offsets. but those spec where from the injector manufacturer when new. 150k miles later. if you can keep the voltage up at idle, there's less chasing trims for it all to do. not as huge on stock trucks, but can be a very big deal in the aftermarket world.

if you're curious about it find a good deal, seems like a 100$ well spent.


instead of all the big 3 kits, I like to move the electric cooling fan load straight from the relay to the back of the alternator. on high these modern fans can pull crazy amps and at higher voltage without the drop from running thru all the factory harness and fusible links. the motors are much happier and so is the factory harness.

I use the slow blow jcase fuses on each fan.

There, again, the factory wiring is proven insufficient. The Big 3 addresses the grounds and charging wires. But the rest of the wiring for the high-amp devices is still too small. Just like those fuel pump "hotwire" kits, the cooling fan could use the same treatment.

Replaced rear glass lifts. Easy peasy

Never had an under-motor splash guard. Put one on.





It feels weird only have one splash guard under the vehicle. My audi had one for the entire front and 1-2 more for the tranny and rear.

Can't Complain about the mechman gives 15.6 at the amp with 0 gauge at startup anyway

Replaced rear glass shocks. Easy peasy

Which struts did you get?

Which struts did you get?

AMS via rock auto.
I've also tried strongarm and stabilus on different vehicles and in my experience most of these perform as well as the OEM lifts

Which struts did you get?

I my case, for my '07,

I used these for my glass recently:

if anyone wants to take a chance on a coldcase radiator there is a new one just posted on ebay # 145092178208 (not my sale)

I gave it a much needed bath.. and a photo session. Then I went home and changed the spark plugs and air filter.

Drove it in the Annie Malone May Day parade here in downtown St Louis



I was right in front of the newschannel 5 van that was livestreaming it on youtube.

You can see the front and rear strobes that the AutoSync can do with the stock lights in the videos below
