Wonder what the laws say regarding child seats ?? That's my big concern.
Im not sure. But I don't have any of those so its not a concern yet.
When I do, I have a portaban and a welder

Lol what are you gonna cut the kids arms off or something and weld them back on! Lol
Since you have supported seats and a seriously worst case of a 60mph + 60mph head on collision, I think you are good to go.
If you looked at how those seats are built and what they're built out of you would change your thinking on the shoulder belt mounting height.
All the info is in this thread now but I don't trust the seats themselves personally
So you would be willing to hit something at 120 mph with this current design despite the recommendations of the regulating authorities?

Dude chill out. You've done nothing but come in here and complain and make negative comments.
The blazer doesnt do 120 Mph. Hell with 4.56s and 33s i probably wont even ever go over 65 on the expressway. Let alone in the sand.
Im building a weekend wheeler, not a race car. Im not going to be hucking this thing 30 feet in the air.......

4 things:
1.) I believe he was talking about head-on highway collisions (60+60=120MPH). Prolly not a high concern for this rig (I'd venture a guess that your setup is going to do much nicer than my stock seat belts), but always something to think about.
2.) Are you getting any welding spatter on that rear seat?
3.) I'm getting a copyright error trying to watch your film clip.

4.) This truck is awesome!![]()


1. I dont think it works that way, I watched mythbusters one time.



Wait...you don't think that you'll feel a 120MPH impact if you are driving 60MPH and you hit someone traveling 60MPH in the opposite direction? I gotta have an explanation for that...
And "I watched mythbusters one time" does NOT cut it...![]()
It was kind of a joke. Im not sure. But what if I hit a car doing 60 while in the stock seat belts that didnt lock???
I think ill be 99% safer than what it was....

) has a nice set of 1998ish seat belts. They actually lock up when they're supposed to, and they DON'T lock up when they aren't supposed to. Really nice. It may be worth upgrading my other trucks someday.

Definitely. (I believe I did say that, no?)
As for what would happen with stock belts...Yikes. I do not like them, Sam-I-Am. They have a mind of their own.

Its weird when your brain turns real life into slow motion in a moment like that![]()
Might as well derail to the max! You know, now that i think of it, if there was a 60+60 head on, all things being equal, you would both stop as if you hit a brick wall. No? You would both come to the same stand still maybe? Either way, I dont think you have anything at all to worry about, but i seem to remember one thing from when i worked in a sand rail shop. It went something alon the lines of, in a wreck the pressure of you flying forward could cause the belts to rip downward through the seat, then, the weight of you flying forward would be exerted downward on your spine. I just dont think thats something for you to worry about, as long as those seats actually do have some type of substantial bracing in there. Does that make sense?
It is! Its an indescribable feeling!
