Seeking to know from all the new products out there, if there is currently any manufacturer making a winch mount system or winch bumper for the front of the new Honda Ridgeline truck.  Also, is there axle mods offered for this truck such as HD differentials, etc.?  

Never seen anything. Since Ridgelines don't have low range they really don't go anywhere that these items are needed, thus the automotive aftermarket hasn't really embraced them at all. And I really can't blame them. Sorry.  

HMMM...MMMMM..UUUHHH...kidding, if your handy with a welder ide tie the subframes ta gedda, then find another irs,hyundai,has some aftermarket support,jaguar has a 44 center,vette,viper,mustang,hmm,tongue is out now, explorer has an irs,let me see, some of the little mitsis had an awd version back in the day,and they drag race the wee out of them, the 300gt,also, doge and chrisler both had versions of the hp car.
