Okay, big project this summer is the full cage. Me and a couple of friends with K5/Jimmys plan to build all ours together. We will tack them and have a seasoned professional complete the welds for safety. Now for my questions... I have 3 different theories for how to tie the cage in to the rig's structure, all with their pros and cons. 1. Build a cage that goes through the floor and attaches directly to the frame. PRO: strong and secure. CON: if the body were to break loose and the cage is still attached to the frame, there could be problems. Also introduces spots for leakage and rust where the cage passes through the body. As teh frame flexes (or tries to), will stress be applied to the cage welds weakening them over time? 2. Build a cage that attaches directly to the body, with no tie-in to the frame. PRO: The cage and the body become a secured capsule. In the event of a rollover where the body comes loose (I have a 3" BL), the capsule or cockpit with myself and my passengers is safe. CON: Would I really be safer if the cockpit/capsule were allowed to separate from the chassis? In the event that the body does nt break loose from the chassis, will the cage puncture straight through it on a rollover and basically break loose of the body? 3. Attach the cage as mentioned in #2 to the body, but then tie it in to the frame via some sort of sandwich plate beneath the cage-body mounts. PRO: Will prevent the cage from penetrating the body. Secures the body to the chassis more securely. Helps keep everything together. CON: What about frame flex? As with #1, won't this apply significant stress to the cage welds possibly weakening them over time? Or add stress to the frame since it won't be able to flex as well? With the body attached securely to the frame now, will ride be compromised as I am essentially bypassing the rubber body mounts? Could I add "body moutn rubber" in the "tie-in/body/cage sandwich" without compromising the strength and security of the cage? I know its a lot, but this isn't an area I want to compromise or do twice. What are your thoughts?
