96-02 4RUNNER FRONT ALUMINUM SKIDPLATE - RA Motorsports
Canadian pricing (good for you Americans) and they are aluminum. They even have a gas tank skid. If you aren’t hardcore wheeling on a regular basis I 100 percent recommend aluminum over steel for the weight savings. If I lived in California or Utah, I would probably personally have steel skid plates, but weight is the true enemy for vehicle driving dynamics. You just need to be realistic about your use case and then decide from there.
Good luck!
