    Lowering kit delete 05 yukon

    My mind is blown. Sure enough RockAuto has lower control arms for coil spring front suspension in an 04 Sierra. Never seen a gmt800 with coils. Very neat.

    Please link - lot of folks have been through this thread already that have obviously never seen it, myself included.

    First Overland / Camping Trip HUGE Success!

    We do a fair amount of wheeling. The Land Rover gets used for the more hard core stuff, but if we're camping also then the Tahoe is 100% the way to go. Nice to just drive it places as well. The Rover gets trailered any more.

    DOD Delete Theory

    Oh, duh. I was thinking it only shut down the intake valves for some reason. Long time since I had a DOD motor open.

    Only 4 custom length push rods, right? Because only 4 cylinders shut down until you get into the LT motors.

    Why is it so impossible to get a gas tank

    Look into bulkhead fittings. May need a tube or a check valve on the inside to keep fuel from coming out, but I'd be willing to bed you could plastic weld the old fitting shut and put a bulkhead fitting back beside it. Doubt either mechanic is willing to do that - that would be an at home job...

    DOD Delete Theory

    OP, I am excited for the outcome on this. I'm with you - I don't see why it wouldn't work. Lots of folks seem concerned about the ticking lifter having caused damage to the cam, but I doubt that would be the case. Lots of hydraulic lifters out there with ticks that are not wiping their cams...

    Headers on 2001 2500

    The 1500 Silverado headers will fit the 2500 Suburban chassis. There are just too many options for them to list all of them in their listing.

    catalytic function not clearing (should I do more parts cannon)

    Just a PSA to everyone reading - do NOT use eBay injectors even if they are labeled AC Delco and come in the Delco box. Chinese fakes in Delco boxes cost me a motor last year. Stuck open and hydraulic'd the motor on restart, bent a rod.

    4wd to 2wd

    Over the summer I did this on an off roading trip after breaking a CV on my Land Rover. I wheeled the rest of the day anyway and the hub did end up separating enough you could see a very noticable lean to the tire when I pulled it on the trailer. When I replaced the hub it has separated more...

    Suspension Uogrades: Leveling Kits vs Lift Kits

    There's nothing wrong with a leveling kit inherently as long as it's installed well. At 3", you probably want 2" shock extensions which can be had for about $20 on ebay. Did you have a front end alignment done after the 3" keys were installed? Not all alignment shops are created equal. This is...

    Partial List of Front Torsion Bars

    Pulled a set out of a 99-02 Z71 Silverado once - don't recall the number or exactly which year, may still have them. They were the same number and not marked differently for LH and RH.

    Tahoe TBSS Intake manifold swap

    You will need the TBSS fuel rails. Reuse your existing injectors, they fit fine with the TBSS intake and fuel rail Get the Corvette fuel filter to regulate the pressure. This will make your firewall clearance a bit tight for fuel lines, but it works. You'll have to bend the fuel rail inlet up...

    GMT800 Coolant hose "Y" connector

    I run green in everything just for the simplicity of only stocking one thing on the shelf. Won't hurt a thing.

    Why don’t my batteries last !!!!

    There are much fewer battery manufacturers out there than there are battery companies - most batteries come from only 2 or 3 manufacturers. I used to buy more expensive batteries, but found it makes little if any difference in most cases. Interstate is one that may genuinely be good - I just...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Depends on a few factors. Tire size, aggressiveness, driving conditions, opinion. I generally do at every oil change. I change my oil every 5k miles whether synthetic or dinosaur. I have had big aggressive mud tires that wanted more frequent than that, but generally 5k is a pretty good spot...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Yes, I've seen that. I'm not too concerned about off the shelf performance parts. More about towing power. 300 lb/ft at 800rpm and 500 lb/ft around 3000, the 8.1 in stock form will be miles ahead. If I ever want more performance I'll have Oregon cam do a custom grind and I'll port the heads...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Found an 8.1 complete with harness, ecm, and engine stand for $600. Going to pull it apart. Valve job, bearings, probably rings. This will be my 6.0 replacement.

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Probably salvageable, but if I've got to pull the heads anyway I'm going to just pull the motor. I've been having some issues with the self adjusting clutch anyway, so we'll get two birds stoned at once, and it will give me good access to really check everything over and decide if I want to...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Broken PAC-1218 in my fresh rebuilt 6.0 I installed over the summer. Has about 9k miles on it. Time to go Cummins or Big Block.

    Upgrading Headlights and Fog/Running Lights

    On your Yukon I would go for the factory Denali headlights. Looks like the TYC's on RockAuto are about $60/ea plus shipping. The lower assembly is just running lights and turn signals. Replacing those won't do anything for light output, but if they are discolored you can get a fresh set on...

    Drill bit size for rough country hidden winch mount

    Killer! Looks like it's not on Android, but I'll get it on my work phone. Thanks!

    Upgrading Headlights and Fog/Running Lights

    LEDs or HIDs are a great option *if* you also spend the money to upgrade to projector housings. Traditional halogen reflector housings should never be used with HID or LED bulbs because the beam patter is wrong and they blind oncoming traffic. Especially folks with night driving issues...

    Drill bit size for rough country hidden winch mount

    Agreed. A little used motor oil or WD-40 goes a long way. Keep high pressure and medium speed, not full speed. I'd just go grab a box set of DeWalt bits at Lowe's, Home Depot, etc. Those are all I use. I've used a whole lot of different drill bits and the Dewalts are good for the money, and...
