    Michelin Defender Alternatives

    The new version seems to be a lot better so far. I had to warranty multiple of the Defender LTX M/S on both trucks, including the XL version, for high roadforce. They did also appear to be wearing g pretty quickly, they were down to 8/32 after 15k miles. If you’re willing to put in some...

    Mystery interior piece what is it for? 2018 Yukon

    It holds the seat belt in the correct place on the shoulder for children or vertically challenged people. Looks like it’s broken.

    Supercruise is worth it in 2025?

    I haven’t seen tire pressure affect it but alignment is pretty important. It’s also pretty important that the steering angle sensor is reset after an alignment.

    2007 Yukon 6.2 stalls/won’t start when hot

    Check that your coolant temperature sensor isn’t damaged. If it is reading a lot higher than the engine actually is, it will cause this. It is very easy to damage and often damaged changing the #1 spark plug.

    Super Cruise is the only thing that makes a 21+ worth buying.

    6.2 Tahoe For Sale

    Yes. 8th digit is always engine, at least as far as GM goes. 5th will tell you if it’s 2 or 4 wheel drive.

    6.2 Tahoe For Sale

    The Sierra Denali only came with a non-AFM 6.2L from 07-13. The 07-08 had the L92 and then switched to the L9H in 09 to 13. There aren’t many Sierra Denali’s for sale though.

    Buy a 1 or 2 owner 2015-17 130-180K mi for 15 or so sound like a plan?

    Absolutely not. 15-17 are literally the worst years. Go newer or older.

    What is the best intake to buy looking for a cold air box intake for my 2010 Lt Tahoe 4x4

    Waste of money unless you have engine modifications requiring more airflow.

    Oil Level Wait Time

    You need to wait 15 minutes with the oil at operating temperature for an accurate reading. It is usually accurate with less time but if you’re looking for consumption or fixing to add oil, you need to wait for it to be accurate. The 2 hours is if the oil is not at operating temp.

    GMPP 6L80 Bolt In?

    I didn’t know you could reuse the stock driveshaft. That should be a killer swap.

    GMPP 6L80 Bolt In?

    That’s what I figured. I don’t see why it wouldn’t work with a TCM and maybe valve body swap with the parts that match whatever year it’s going in though.

    GMPP 6L80 Bolt In?

    It has to be the TCM and maybe the valve body depending on what your truck has in it. The hard parts in the transmission are the same for all years of 6L80 and all updates were backward compatible except for the planetary that was changed in 2012 and you have to use the different speed sensor...

    GMPP 6L80 Bolt In?

    I thought about the TCM shortly after I posted. The description says it comes with a USB drive with the calibration files for the different crate engines. I know there are multiple TCM part numbers between 07-14 and you need the correct one to program it. I figured we could probably get the...

    GMPP 6L80 Bolt In?

    I’m wondering if anyone has experience with the GM Performance Parts 6L80 part number: 19366637 and knows if it will bolt right into a truck that came with a 6L80? I don’t really see why it wouldn’t, the gear ratios are the same. Looks like it costs about the same as the reman GM transmission...

    If you didnt have a Yukon/Suburban/Escalade, what would be your next choice?

    Yes, the GM’s do have more cargo space than the Fords, but the Fords have more passenger space for the 2nd row because of it. Depends on what you want more. I don’t know why you’d want the whole car larger though, they were already a tight fit into a garage. I know someone that bought the...

    If you didnt have a Yukon/Suburban/Escalade, what would be your next choice?

    The fold flat seats are just an illusion created by the floor being raised up by the storage compartment, so you’ve lost height, and it isn’t flat, so all your stuff rolls out when you open the liftgate. I wouldn’t call that better at all. It is very inconvenient to have to take the third row...

    I would not say that.

    2014 Denali 2WD to 4x4 Conversion

    Are you swapping the frame? There’s nowhere to bolt the differential on a 2WD frame.

    2013 Escalade ESV Windshield Replacement

    The OEM glass is much better quality, in my opinion. I’ve had a number of Pilkington windshields as every glass company I’ve used say they’re the best aftermarket glass. They get “sand blasted” much faster and the wipers skip across the glass (I only use true OEM wiper blades). I feel the optics...

    Aluminum / XFE NNBS Front Suspension Rebuild

    If you’re at stock height, it makes much more sense. But, the only way to get aluminum arms now is to take your chances on quality with aftermarket replacement parts because the OEM aluminum arms have been replaced by the stamped steel, which weigh a tad more. Still less than the iron ones...

    Aluminum / XFE NNBS Front Suspension Rebuild

    Yes. That’s why I didn’t go that route. I figured if I wasn’t going to use the aluminum knuckles, there was no point. The knuckles are the only part that is 100% unsprung weight, I don’t know the math but since the control arms are attached to the frame and the shock, the weight reduction of the...

    Aluminum / XFE NNBS Front Suspension Rebuild

    The knuckles are different for the different size ball joints. For some reason, they want a lot more money for the knuckle for the larger joints for the aluminum/stamped steel arms.
