Big Scott I appreciate your concern, and am truly saying this with the utmost respect, but I want to ask if you know what the tensile strength of A-36 steel is? its around 30k PSI.
Do you know what the tensile strength of a weld is? It varies, but typically you can assume around 70K PSI, mainly due to different strengths of electrodes, but there are many other factors to consider , mostly, the quality of guy welding it,which I don't want to elaborate on right now.
Do you know what the tensile strength of JUST 1 grade 8 bolt is? 150k PSI.
I will have this cage done this week. this will not "punch through the floor"... from any of the interior 2'' "down tubes" there is a 3.5''x3.5'' x.1875'',interior plate with 4, .5 '' holes, directly beneath that is the sheetmetal of the cab, beneath that is a 4.5''x4.5''x.1875'' plate (this reduces the chance of shear, and is the proper way of putting 2 bolted plates together, IMO), and this obviously has 4, .5'' holes in it as well. From there, is another 2'' tube with a bend in it that extends to the frame which finally ends in a .1875'' plate with 4, .5'' holes in it that will fasten through the frame. this will happen in 6 places on the frame. BTW, I am designing this cage as if it was a full weld-in, only making the parts bolt, that allow it to get shoved into te truck!
I will reiterate
"Just because you have this cage, or any cage (WELDED OR NOT!!!!!!!), in a somewhat stock Raptor, doesn't mean you have a TROPHY TRUCK! You have to drive within your limits and the vehicles, and if your doing that, but you have an "oh shit" moment, this cage will protect you. If the day you get your 2013 and install this cage, then head straight to the desert for the first time ever and do 120, bad things are bound to happen."
Finally, everyone should get there engines welded onto the frame, there are literally only 2 bolts holding that damn thing in there, what the hell Ford!!! same with the whole suspension, and the cab only has 4 bolts holding it onto the frame!!! RPG, quit bolting on bump stops, start welding them! same with those Fox 3.0's weld those ******* in... come on what are you guys thinking!
I am quite certain, most people (including people in the know) will agree this cage is exremely well built, and is a good option for someone looking for a little added security, as well the abilty to run 4 or 5 point harnesses.

Uhhh, you forgot to mention welded wheel studs. Those sons of ******* are holding the wheels on...
Trust me when I say we know the controversy of bolt vs. welded. The one point that often gets lost in translation, and I think you hit on it rather well is the integrity of the welder doing the work. Corey has a good buddy that was severly injured from a weld breaking in a bad roll over a while back. Bottom line, just cause it welded, doesn't always make it better. It wasn't long ago the vast majority of Class 7 trucks had bolt in cages.
A few months ago legendary Ford Rough Rider Dave Ashley was at the shop for a few hours and this very topic came up. Dave has better knowledge than almost anyone in this subject because he still volunteers himself to be a roll over dummy for Ford. One thing he couldn't stress enough is how strong the new A-Pillars are on these trucks. This isn't to say re-inforcement is a bad idea, but rather to make the point Ford has given us a very strong cab to build around.
I always cringe when I hear people on the internet speaking in absolutes when they have no clue of the design concept or have 100% of the design details. Personally, from what Jimmy has released, it appears to be a very well thought out product and I'm glad he pointed out the strength of grade 8 bolts. If a very bad rollover happened, you would be more likely to break the weld from the plate than break off 4 grade 8 bolts on each mounting plate.
Either way, I know this debate isn't going away anytime soon and I told the wife I would actually take a day off from the Raptor world for 1 day now that I'm home from SEMA.
Good job Jimmy,
