What will the United States Secret Service start using? I kind of thought general motors kept the 3500 HD sub alive for government use. It sounds like from your report they were purchasing most of them (if only 88 were made). I’m curious what you think.

Yea you would think that the 1500 SUV Diesel would be a no-brainier but we will have to wait and see. When the 2016 3500 Sub cam out there was a LML option for it on the order options but never came about, these days the 1500 with its 9.5" rear diff and 400+ ftlb motor options is so stout it can do most anything the general public needs.

The fact that the 3500 Suburban was targeted towards fleet sales probably goes a long way towards explaining why it never saw much sales.


I would still attribute the fact that out of the factory - it had an abysmally low tow rating was probably what nailed the coffin shut though. If it wasn't for that I bet more people would have actively sought the thing out so they could get their hands on one for tow duty (similar to the old 2500 Suburban/Yukon XLs)

Ever watch the news reports from the White House? Look in the background - the government appears to still be using quite a few of the last generation 2500 SUVs.



Maybe one of the reasons for poor sales was that the Govt. just didn't have that many vehicles that needed replacing.


Seems like GM has demonstrated that the frame under the 2500/3500 SUVs is good for either hauling a very load in the truck - or pulling a very heavy load behind the truck (the old 8.1L SUVs had a 12,000 pound tow rating if I remember correctly).


If GM wanted to sell more HD SUV's maybe they should offer up some different options, so you can get one built for it's intended purpose.

I haven't been able to wear out my 2005 2500 Suburban yet, so that is one reason why Arlington didn't get an order from me for the 3500HD.

I would love to know how to adapt those larger brakes from the Suburban 3500 into my 2010 Yukon XL 2500. I like the look of some of the new wheels for the 8x180 bolt pattern too - so having a set on there would make for a nice look .


I suspect that putting the larger brakes and going to the 8x180 wheels is a pretty simple factory parts swap - since the 3500 uses the same CCSB frame as the older trucks - but as of yet I haven't been able to figure out what exactly it would entail.

I have seen the background and that is why I asked! You know they have a replacement plan in place for the presidential motorcade so I wonder what their future plans are? Just a thought!

We are going to switch over to the 3500 CCSB and mode the frame for the Suburban

Yes you can switch over to the 8X180 the ABS systems are the same but to keep the wheel speed sensors happy you will need a 10.5 HD rear diff from a 2011 or newer gas PU. you will also need to change the front spindles to bring over the bigger hubs

Can you just order a new replacement 2500/3500 SUV frame and build that up using the CCSB parts?

They were only fleet orders. Any way, I couldnít order one unless I found someone to order for me.
