Calmini's Front Bumper Question

I have a 2002 Xterra and I was wondering if the added weight of the calmini bumper would affect the warrenty of my vehicle. I've heard the ARB one is so heavy it voids pretty much the entire front end warrenty. Any comments (nice preferbly) would be appreciated.

hattrik, the added weight of our bumper and a 8k-9k winch will be at least 175lbs. Unfortunately, we don't get to make the call when it comes to your warranty. Call your dealer and ask. -Steve.
