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

[Sam Harris]

Damn I paid 90 bucks for from fronts and a brow. Sunroof was 20 bucks. Im going to have him do the rear 5 windows later this year for 140.


Also...I may or may not have started on my retrofit tonight....which possibly included up to the test fit and alignment of a projector in 1 headlight.

And I’m hoping you may have a photo-documented reference of said possible mod...

I have been taking some pictures so far of said possible mod.

Just finished up a whole bunch of maintenance and repairs that I had been putting off. My tahoe has 140K on it but the engine runs great so I’m going to keep it for a while. I finally decided to finish the work after my G80 rear differential blew up. It’s one hell of a list:

Oil pump, water pump, timing chain, replaced the leaking oil pan gasket, H3 motor mounts, Yukon limited slip differential, replaced both front hub bearings, transmission fluid, transfer case fluid, front differential fluid and axle seals, tie rod ends, spark plugs/wires, cleaned throttle body, replaced leaking power steering hoses, replaced rear brake calipers, pads, and rotors. Replaced leaking brake master cylinder.

Also, I needed tires so I went ahead and got some Fuel Trophy 18x9 and some bigger Duratrac 295/65r18 tires. I wanted more rubber than my 275/60r20s.

Nice! How much stiffer are your h3 mounts. I did mine and a cam at the same time so it shakes noticeably more than it used to but how is it on a stock engine?

I feel a little more engine vibration at idle but it isn’t that noticeable. I’m just hoping they hold up a lot better than the stock fluid filled junk they put in these trucks.
What cam did you put in and how do you like it?

Both the stock ones in mine were shot to hell and back when I got the vehicle. Interior rattled and there was a thunk on acceleration. I hated it. H3 mounts installed and a Texas Speed Low Lift stage 2 were used. They say in a vehicle as heavy as ours, its as big of cam as you can run without a higher stall converter which is something I wasn't willing to do. They say its supposed to be a 50ish hp gain at the crank which is about the neighborhood I'd fall into. I don't have a before/after but I did make 295 whp on a 92 degree day on 1/3 of tank 87 octane and the other 2/3 filled with 92. I'm on a 2007, so no vvt. The cam is great. They claim below the curve gains are up to 70 more hp vs stock which I think might be a little much, but damn if it isn't a kick in the pants. The vehicle "comes up on the cam" above 3200 which I wish was lower, but you sure as hell don't loose power down low from stock. Basically, it feels like the trucks got vtec now. I also got rid of my cats, so any slight- and boy do I mean slight- hesitation happens right off idle. Its probably a combination of the cam and going catless, and the fact that I need to change my ATF all stacking on top of eachother for the hesitation. Its not noticeable to anybody but me, but YMMV.

The cam made my tahoe faster, no drop in MPGs which almost pissed me off, and it also sounds pretty cool at idle.

That sounds great! I’m adding this to my list... only worry is I don’t want to lose any bottom end.

above 1200 which is the stock stall speed you’re not loosing any. Esp if you are still emissions compliant.

if you have the 6 speed and/or 4.10s you won’t be able to tell I don’t think

Sounds great.
