Roll cage design question

[jt512]

I'm trying to plan out my the in cab portion of my cage for the K30. It will go through the cab and tie into the main hoop of the tube bed.

My question is in regards to the A pillar design, I will be going down through the dash and tying into the slider and frame. I've seen some cages where the A pillar tube then follows the roof and ties into the B pillar hoop, some cages use an A pillar hoop connected to the B pillar with short tube sections, and lastly some use short tubes on the A pillar and a "C" shaped section that attaches to the B pillar (like a 3/4 halo).

So what way is best / worst and why? This is my first real from scratch cage build so any input is appreciated

the 3/4 halo would be the easiest to do i would think...

of course I chose what I feel is the most difficult to do, the A pillar going all the way back to the b-hoop... those where 2 difficult tubes to say the least, about 6 hrs a piece...

There is no best way.

It really depends on the headroom you need.

Making your A pillar your side bars too creates the most headroom for the longest distance.

But a full halo done right can have just as much headroom, I just think its a touch harder to do.

Of course I have done cages where I have bent the A pillar as one piece, don't do that, I had like 8 different bends, in 3 different planes. Looked great but took forever.

When I do the cage in my Jimmy it will probably be the A pillar downbars feeding back to the B pillar.

Ya, in a std cab truck like mine, I'm leaning toward the 3/4 halo, especially because I have to go through the cab, unless someone sways me away from it.

I went with an A hoop and B hoop tied with smaller tubes front to rear. Windshield out is the only way to do it. I lowered my seat location, so head room was never an issue.

Whatever you do, by Bend Tech Pro software. Will save 3 times it's cost in metal.
