Understood about actual crash testing being the best, thanks for making the point about the variables.One thing to keep in mind regarding crash bars, a stronger design may not mean a better design. You want the materials to absorb as much of the energy from a crash as possible. If your super strong crash bar snaps off the bracketry that's holding it, that is not a better design.
There's no substitute for actual crash testing.
The other unknown is one would think a wider tire would do less intrusion into the cab than a stock narrow tire.
Again, no substitute for actual crash testing.
All that being said above, is there a consensus about installing aftermarket crash bars being more risky than other modifications? Lifting a truck 6” and moving it’s center of gravity higher certainly increases risk, seems like all suspension modifications carry some risk. So where do aftermarket crash bars sit on the risk scale?
