Adding in more tube in stratigic spots, gusseting, and adding more points of contact to the floor are all ways of increasing the Smittybuilt cages strength.
I run part of a Smittybuilt cage, the front down legs. It is an ok setup. The legs contour really well which I like. I added in 2 spreader bars in under the hardtop between the windshield bar and Bpillar bar. I also gusseted around the Bpillar downlegs to strengthen it. I am going to add in more tube very soon to do all the things I mentioned to make the cage stronger.
Right now my cage is 6 point, I want at least 10 pt. with good gusseting and triangulation. I have already flopped my truck once (very softly) and it landed on the cage. The cage was fine but now that I have used the cage once offroad I know it is going to happen again so I want a cage that is going to take a pretty violent rollover and survive.
One of the things I am most worried about is a high speed roll on the highway. I want to make sure that the cage will protect me very well for something like that should it happen. As my cage sits right now it does great for the type of rolls I see while offroading here in AZ, and is satisfactory for a highspeed roll. I want more though.
Anything is better then nothing though. So get something in there and then add to it later if you need too.
