all you have to do is go to AM generals website...they have all the upgrades listed for the model truck.
you can also just google it....but FYI, these aren't H1's, so using an H1 model year change chart won't do much good for a HMMWV.
Just saw this. I understand they are different. And a lot of things I'm seeing will be assumptions.
But for example, in 1994 the H1 changed to beefier half-shafts, new fuel tank design, new propeller shafts, new radiator. 1995 saw new ball joints (which were improved continuously after that), upgrades to pitman arm, idler arm, new control arms, etc.
Going all the way to 2001, there are things like another design change to a heavier duty pitman arm and idler arm. New design for seals on geared hubs.
And so on. Now... I don't know that all of these were on the HMMWV. Several modifications like ABS, or undercoatings to reduce noise, or increased strength of a door hinge and things like that, I would not expect those on the HMMWV. But the purely mechanical improvements could certainly be.
I looked at the Humvee purchase like I had one of two basic options:
1) Buy a complete truck that had generation 1 everything. 6.2, TH400, steering and suspension components, etc.
2) Buy a truck with what I call generation 3 everything. 6.5 Optimizer, 4L80E, 242 T-Case, upgraded steering and suspension components, etc.
Since I'm in Virginia, it appeared what I'd have to do for a title was going to be impossible with Option 1 unless I spent the same $$ as Option 2 and got the truck from another state. While option 2 came with an incomplete truck, I saw that as an opportunity to make it exactly what I wanted it to be. Looking around at steering and suspension components if I wanted to upgrade an option 1 truck... the prices were pretty staggering. So option 2 seemed like the easy choice for me. This thread made me concerned I actually had an option 1.5 or generation 2, if you will.
I plan on putting this truck to work with a matching M1102 on my property.
Lots of steep hills and rocks. And I only have 8 acres!
I can't wait! I've been bitten by bug pretty badly...
