In order of importance for protecting your sheet metal? or your expensive bits?
If sheet metal is your concern.
Rocker Skids #1 most damaged sheet metal.
If mechanical protection is your aim.
Front Skid (aftermarket 4x4.. Sean Devinney.. the best I have yet seen for sale, yes I have one)
Transfer Skid (calmini's is OK)
Trans Skid
Rear punkin protection... maybe truss like Calmini, but I hate the loss of clearance (No, I don't have one)
I have been wheeling this little guy for months with stock bumpers.. don't really see any need for aftermarket, except for recovery points.. I mean, I haven't hit anything with them.. but if you tend to hit trees a lot, then yeah, I guess you need heavy, expensive aftermarket or manufactured bumpers.. yeah they look great, and they are on my list... but never have been top of list, and I haven't needed anything more than stock so far... (fingers crossed) I think I will just get the Trail Tough bumpers.. about $300 each.. much cheaper than the competition, and they look better too.. (MUCH better than that abomination ARB sells.. that thing is UGLY)
Cage is near the top of the list too.
