In my opinion ratchet straps, ratchet straps and more ratchet straps. Broken arm? Strap it back on. radius rods? Strap it on. Broken axle? Depending how it breaks, might need to strap it out of the way to keep it from doing further damage while you limp home. Can be used in a pinch to aid for recovery and winching. Use em for rope. Everything.
Belt, belt change tools, tire plugs, air compressor, jumpers (or jump box if riding alone) and like 90 million ratchet straps and you good to go.
If you break axles, just limp home in 3wd and change it at home. The first time I swapped my rears, they were so stuck, the ole cup stuck in the diff happened… It would be nearly impossible to do trail side unless you had a 27mm socket, huge 1/2” breaker bar, 10lb slide hammer, 3vise grips, etc etc that’s just unrealistic.
