    The stock differential is the weak link for sure. You're not talking about a lot of weight though, I wouldn't worry about it at all. The towing capacity on these trucks is around 8,000 lbs stock. Add a little more horsepower and some better brake pads and rotors and you can tow 10k pounds all...

    Axle

    Are you referring to the stock 10 bolt? I'm still running stock axles and 10 bolt housing... Install some good bearings, a TrueTrac and send it. Upgraded driveshaft is also a must IMO if you're high HP. I upgraded to a 1350 yoke as well. You've got 40% of the power going to the front if you're...

    Sorry I'm late to the party... Moving up to a 9.25 will not do you any good for improving launches. You're still stuck with an open diff and no limited slip or posi units available for either the 8.25 nor the 9.25. I am still running the stock front diff on my 1k HP Denali. The transfer case in...

    2" vs 3" spindles

    Not 100% sure but I am running the 2511 on my AWD 2007 Denali... I would call Belltech to be sure. The 2509 does say 4WD though: "2007-2014 GM Tahoe/Yukon/Avalanche/Escalade/Denali 2WD/4WD and 2007-2014 GM Suburban/Yukon XL 2WD/4WD" According to the Belltech site, the only thing the 2511 says...

    2" vs 3" spindles

    I'm not sure what type of build you're doing but I would go with whatever @NORCAL SS thinks is best... I didn't run the drop struts for too long and ended up going with a QA1 coil over conversion from Atomic, before Norcall SS offered his own kit. Way better ride and adjustability with the coil...

    2007 Yukon Denali Build (This got outta hand really quick...)

    L94 and L92 are pretty much the same motors. L94 was 2010 model years and up and are still a basic LS3 rectangular port head. You have AFM you're gonna want to delete and VVT too if you aren't sticking with a VVT Cam which I don't suggest. Used CTSV kit you mentioned is def a cost effective...

    2007 Yukon Denali Build (This got outta hand really quick...)

    100% will do. I’ve got a Dragy too so I’ll get video from that and another cam inside as well as outside. If it ran 124mph in the quarter on a heavy ass 32” snow tire with a crap launch, it should have no problem with a deep 10s pass now. That pass was in 2019 on 93oct and without my CNC heads...

    2007 Yukon Denali Build (This got outta hand really quick...)

    That’s a good start for sure and a good price on a blower, just know you might need to replace the bearings and isolator. Easy to do if you’re mechanically inclined. You could just do a light rebuild on the motor, just bearings and a hone or .005-.010” cleanup if you’re lucky. Rebuild the L92...

    2007 Yukon Denali Build (This got outta hand really quick...)

    I guess that all depends how crazy you wanna get with it. I started out just bolting a stock LSA on the my stock 6.2L and tuning it with HP Tuners. My truck had like 155k miles so lower oil pressure than I liked. Ended up building a stroked 6L with my rebuilt L92 heads. Then eventually added CNC...

    2007 Yukon Denali Build (This got outta hand really quick...)

    I’m glad you found it helpful. I’m still around, just haven’t posted too many updates lately. I’m hoping to hit the race track in the next week or two before Dream Cruise so I can make my first official 10 second qtr mile pass. Happy to help if you have questions. Great community here with lots...

    Actually selling it.....Pulled

    You need to chill out man. We all know Drugs are Bad, Mkay... My apologies and no disrespect but it's a VERY common expression used when someone comes to you with a crazy or stupid idea, kinda like when trying to sell a vehicle for $25k (300%+) OVER a fair realistic value. I could have phrased...

    Actually selling it.....Pulled

    I don't care how much your truck has been gone through. It could have a brand new crate motor (which it doesn't), a brand new transmission (which it doesn't) with a 100k warranty along with a pristine interior and zero rust... you still are not gonna get anything close to $20-$30k for that...

    Wiring is wrong, you should not need to program it at all unless you want the mileage updated...

    Escalade Cluster in NNBS!

    I've tried before but you can also try to contact https://www.mouser.com support and see if they can help. Give them the connector number on that picture and see if they can find the other end of it. Their support is pretty good...

    Mishimoto 1999-2014 GMT800/900 Performance Radiator R&D

    That’s a stupid comment to make with absolutely no context or relevant information regarding why. I’ve had mine installed in my 2007 Yukon Denali for a few years now with no problems. Works much better than the OEM one and I have not had any issues at all. *I should add that I purchased it...

    Performance on a 2007 GMC Yukon Denali

    Not sure if the OP is serious about this build and 10 second goal but I can tell you it is possible for sure if you have the will and power (money too lol)... Probably an easy $15-$20k if you do most of the work yourself. Easily $10k into the motor build, a solid $5k into the 6L80 build, maybe...

    Traction control question

    Honestly for me, traction control and more importantly StabiliTrak do way more harm than good. Stabilitrak is probably the reason you spun out. With my ABS fuse pulled, I can drive my 1,000hp Denali in the snow with NO problems. Good tires make a huge difference but I've NEVER spun out, even...

    Escalade Cluster in NNBS!

    Yes it does, the only thing you really lose is oil change life... If you get a KPH one from out of the country, you can also change it to MPH in the settings and then you get a 200mph speedo as well, not that I would ever need such a thing ;-)

    Anyone running Spohn Rear Control Arms?

    Shop around a bit, you'd be surprised... This place below I had bookmarked for years, I just saw they have them listed even cheaper. I remember talking to them and they use a different caliper in the rear (size of pistons) to better bias the brakes to compensate for the 16" front. I can...

    Anyone running Spohn Rear Control Arms?

    Not sure where you're shopping but I got my Wilwood set, front and rear for $3,500... Fronts are the 16" Rotor (#1408992R) and rear are 14.25" (#1409407R). Bought mine from Autoplicity but you can shop around. Wilwood 140-8992-R TC6R Front Kit,16.00", Red SKU: WIL-1408992R $1,956.99 Wilwood...

    Beware When Ordering

    Kinda funny I’ve had the opposite experience. I’ve had great luck the few times I’ve had to order from CarID when the part wasn’t in stock at Rock Auto, Summit or Amazon. I called twice to price match and they gave me a way cheaper price on a few things including wheels and tires (which I used...

    AWD help

    No viscous coupling used since 2006 and previous... If the Sierra had a selectable AWD system, it was probably the MP 3023 which is also planetary gear sets and synchronizers for shifting. I believe it does have a "clutch" simply for the shift process but it has nothing to do with the drive...

    Let’s talk transmission temps

    I figured I would chime in here since you guys were getting in a pissing match over the electric fans... @03_GMC is 100% correct and everyone else arguing with him is wrong. On these trucks, at least with the E38 controller, the electric fans are only triggered on or off based on ECT and AC...
