Default Re: Nitto Mud Grapplers vs. KM2's

They're called "Rock Monsters" and they are manufactured by Hutchinson who has the military contract for all the beadlocks used on all vehicles currently deployed in Iraq. The Rock Monsters are the only DOT approved double beadlock wheel, and I've cruised out to Moab and back at 80mph on the interstate with no fear that these wheels would come apart. They have a 4.5" backspacing so you will gain a 2" wider track width compared to OEM wheels which have 5.5" back spacing.

They are very easy to assemble, took me less than an hour to mount my new BFG 37" KM/2's on each wheel. Check out the link below for installation docs and videos.

They are not cheap, about $460 per wheel and you can add $50 per wheel for UPS shipping direct from Hurchinson (located in New Jersey). They offer them in polished aluminum or powder coated black. The only reputable dealer IMO is Expert Offroad located in Kansas and Texas. I dealt with the Kansas location. I've posted a link below where you will find the phone numbers.

I've "lifted" the front end of my H2 about 2" by cranking up the torsion bars.
