    SUV vs. Truck 6.0

    The difference might be flex fuel vs not. The L96 is supposed to be a flex fuel engine but the one in my 2018 Suburban 3500 is not.

    VVT cam gear question.

    I've had good luck by calling either Summit or JEGS when I've had a question like that. Their techs usually know what's up.

    Gear Ratio Change: Looking for Your Results, Comments

    That's going to make a great towing setup! Being able to run regular or even mid-grade is huge. Filling the tank with premium every 250-275 miles stings the wallet a bit more than I'd like. I had Blackbear tune my Suburban 3500, and Justin had some helpful comments about how to run it. I had...

    Will a DOD delete fix a lifter tick?

    The perfect vehicle for the mission!

    I agree with you. And, 2500 is a really nice, comfortable towing RPM. If I need to wind it out to 4000 or 4500 to get up a big hill and keep up with traffic, I have no problem with that, but I like it nice and calm and quiet when I’m just cruising along.

    Gear Ratio Change: Looking for Your Results, Comments

    One more perspective that hit me this afternoon. The difference between 3.42 and 3.73 is a little over 200 RPMs at 2500 RPMs. But the difference between 3.42 and 4.10 is just over 400 RPMs. At that RPM range, lots of things are happening. For one, you gain 35-40 HP (about 25% more) when you go...

    It runs in 5th, 95% of the time when I'm towing. Occasionally I'll let it upshift to 6th when conditions are suitable. I rarely need 4th around here - especially towing the considerably slipperier (and lighter) Airstream.

    Thanks for remembering, @swathdiver. Towing a heavier camper as @Foggy does, I would be inclined to go with 4.10 gears over the 3.73's. I have the 4.10's in my 2018 Suburban 3500, and it's just enough to keep it in 5th most of the time on the highway when towing either of our campers, but I...

    2004 6.0 NV4500 Tahoe

    I forgot to add that it kept throwing the old tensioner belt after I installed the new compressor. I put a camera in there to watch when it would happen, and it was always when I had to step on the gas to accelerate quickly, like merging into traffic. Speculation on the interwebz at the time was...

    2004 6.0 NV4500 Tahoe

    Keep an eye on it. I thought the problem was my tensioner on my 2007 a couple of years ago because the A/C compressor kept throwing its belt. Turns out it was the compressor on its way out. I took off the A/C idler pulley and installed a new compressor and a stretch belt (I used a 2012 Yukon XL...

    Billet torque converter, best value?

    I have this one from Summit in my 2012. It's a reman OEM but with a flanged hub, billet cover, and stronger lockup clutch. https://www.summitracing.com/parts/ccv-tqbu60fhd?rrec=true

    New luk torcon converter

    On an ‘08 Denali, clunking on a downshift is most likely to be (in order of probability): 1/ Driver’s side motor mount 2/ Front differential mount bracket bushings 3/ Transfer case chain slop This has been the case for other folks here, and it was the case on my ‘07. I addressed 1&2 a few...

    2020 Suburban with awful roaring noise

    I've had a wheel bearing sound like that when it failed. Any leakage around the right rear brake backing plate?

    Chevrolet Suburban 3500 Questions

    Wow...hope it proves to be a legit good part. Something else for me to keep an eye on. I'll also keep an eye out on the junkyard network for a wrecked one I can grab the box from and rebuild it on the bench. Thanks for clueing me in to the issue.

    Chevrolet Suburban 3500 Questions

    Yeah, the HP axis doesn't line up with the lines, so it's a bit of a visual guess. I gave it another pass and hopefully got them a bit closer.

    Chevrolet Suburban 3500 Questions

    The question of 6.0L LS vs 6.2L LT performance was rattling around in my head so I did a little google-fu and came up with the following. Note that the different ranges on the charts distort the picture. Anyway, figure 2500 as a nice, relaxed rpm for towing and you can see the difference between...

    Man, you guys are packing it in! Last time I was at Devils Tower was in about ‘96, driving my old ‘82 Celica and the temperature was -20°F that evening.

    Denali XL 6.2 salvage build, plates paint wrap SEMA

    Glad the show was a success for you. Bummer about the project but it doesn’t seem to have stopped you from lining up partners. Bueno. The virtual test-fit platform looks intriguing. Clear messaging on the booth. A lot of companies get that part wrong - companies who should know better. Nice.

    Yeti's Very Long and Slow NC Home Build

    Did you leave the heat on in the house, set to at least 58ºF? That should be enough to keep anything from freezing, including any plumbing in the exterior walls. There shouldn't be any, but I've seen some dumb shit since moving to Richmond that I never would've seen in Colorado. They don't heat...

    Project Polar Bear: 2005 Suburban 2500

    Oh man... back in 2017, I rebuilt the ZF 5HP24 transmission in a '98 740iL on my workbench, and did a whole bunch of other fixes while I was at it. Valve cover gaskets, timing chain guides, heater core, radiator, all belts & hoses, front suspension, dashboard LCDs, alternator, cup holder, pretty...

    Was wondering what happened with that trip. Glad the Yukon performed flawlessly. How was SEMA for you?
