Alan got most of it all right but just to clarify.
Ground clearance lost is 1/2".
Difference in weight from factory is is about 150 lbs.
I am not sure how you would go about repairing the rocks that will be damaged by the impact from the front skid.

Seriously the only additional difficulty is dealing with the additional weight. Other than that it is removed and put on very simlilar to the factory.
Yes the bolts will be upgraded and recommmended that small modifications are made to the H2 due to the weak mounting holes.
The additional weight is nothing to the H2. The H2 is equal to a 3/4 ton vehicle so it will not have any problem handling the additional weight of the Underbody Protection.
Warranty is not effected. There have been no mechanical changes made whatsoever. There are not even any additional holes that have to be drilled. The only mod that is suggested is drilling out and upsizing existing factory holes.
Still working on the final details of the pricing.
All the bolts are concealed or protected in some fashion. So damaged to a bolt is low in probability.
No worries about additional stress points, as stated by paragon round holes do not create them, and we are not adding any holes just making existing ones slightly larger.
