    Chevrolet Suburban 3500 Questions

    In October a 3500 LT popped up, but sold almost instantly. I've been waiting to see if the owner of it would show up here...

    What tires, and do you have stock shocks on it? Bilsteins made a world of difference on my 2500, as did going from the OE Bridgestone Duravis to Michelin Defender LTXs. When those where done I went to the newer LTX2 and they are even better.

    On a road trip in my '08 2500 from Philadelphia area to Seattle, WA (then back). Caught a pair of armored 3500's in the wild. Just off I90 in Blue Earth, MN. My white 2500 with the photobomb on the left...

    Ah, thought you had just gotten it. Saw it’s a LT. Nice find.

    Curious where yours came from. I’ve been watching what is available around the country and didn’t see that one, unless the wheels and other stuff went on after you got it.

    The GM software only allows you to program a module for a vehicle that it available on, and you need a VIN to do it. For example, my 2500 originally came with tow mirrors and a prior owner had swapped on non-tow, power fold mirrors mirrors but didn't change the door switch module to one with the...

    Assuming that the issue is a no-comm (which jives with the report above), the message is being triggered one of two ways. The first is that the cluster itself is monitoring the presence of the steering module, and reporting the fault when it doesn't see it. The other is that some other module is...

    Are you sure it even has one? If your cluster came from a 1500, it could be a no-comm error because it's not seeing a module it expects to see. Check for codes in the cluster itself to see if there is a no-comm code.

    Chevrolet Suburban 3500 Questions

    I'm quite familiar with how the ratings are done, and this is simply not true. The testing is done on a dyno with a test cycle that includes simulated hills and varying speeds. While there are certainly lots of variables and "your mileage may vary", it is very possible to exceed the highway...

    Chevrolet Suburban 3500 Questions

    I was curious because I've seen lots of different numbers out there for them and they seemed higher than I'd expect, like 16/23 which can't be right. Since it's a 3500 and the EPA doesn't require fuel economy testing on the 3500s you can't look it up on fueleconomy.gov. I wouldn't expect it to...

    Chevrolet Suburban 3500 Questions

    Off on a tangent... curious from those of you who have gone from a 08-13 2500 (6 Speed) to a 3500, is your towing mileage any different? The 3500 has 4.10s vs 3.73s on the 2500, but with the 2500 towing close to 10K it doesn't spend much time in 6th except going down hills.

    All of that information is in the upfitter manual that I linked to above. Did you look at it? For example, X300 is that big connector. Here is an example.

    Just spend $22 for a 3 day subscription to GM TDS, and download everything you need. It will be money well spent for the time it saves you.

    Chevrolet Suburban 3500 Questions

    I can't find a 2016 order guide, but I did find a 2018, and in 2018 the heated seats were LT only... but I have seen a 2016 LS with a console and heated cloth seats. Does anyone know if the wiring is there for heated seats? If I could swap in heated seats and a console to a LS that would be nice.
