Came right of the frame horns, replaced the rubber mounts with tubing, plated on top of the tubing, sandwhiched the cab with plate on the top, bolts at the corners of the plate and one right thru the center where the factory bolt was, there will also be a few other spots where it ties into the frame but still deciding where I want them. 1.5 120. wall to if anyone was wondering.

One safety concern I had was the 2 bars behind the bucket seats that are straight up and down could be VERY dangerous! If those bars break in a roll over they would likely go right through you!

I'd also be a little concerned about head clearance on those downtubes behind the driver/passenger.....especially with a helmet on. Otherwise, it looks good.

Yeah checked the head clearance with a helmet on and its 3-4 inches all the way around and I believe score wants 3 inches of clearance. On those down tubes, how about putting some 1.5 in the corners to help distribuet the load in event of roll over. something like this.

Now your getting a little out of control. That would be a lot of tunbing in one area. maybe move the tubes so they go from the top center of the hoop hoop to the bottom of the main hoop. But otherwise not bad.

You definitely DON'T want to put any bars pointing at your head like that! Again, if they shear off then they go straight for you! When you build the cage just think about what can happen with the tubes in a worst case scenario...where are the tubes going to go?

Myself I would take out the two bars and replace them with one bar in the center , meeting your center roof bar . Then off the bottom I would run an inverted "V" that meets the bottom of that tube and goes down to the frame . Otherwise those two tubes are useless in a rollover . They don't go to anything .Just my .02 cents .

Ok I think Dans idea wins then, the tubes as of now have tubes under them at 45's down to the plates in the floor which go to the frame. So something like this then. How it is now #1 Dans idea #2

Thanks guys for the input I've been going off how my friends trucks are done but I wanted some other opinions, would rather do it right once then find out the hard way.

Looking at the truck today, removing those bars helps eliminate (sp) another problem, there right in the way where the belts would hook up to the rear bar. So tomorrow out they go, man I wish I had A/C in the garage

What's in there now ? If it's 9.8 metric or better I wouldn't bother.


Look for places to tie the cage to the cab, and do it.

No its just a cheapy from Home depot to get the holes lined up, and yeah it will be tied into the frame at four more points in the cab.
