I am thinking about putting a leveling kit on my 2011 fx4. Will this void any type of factory warranty and which kit would be the best to go with.

 

I have never had an issue with a level kit and warranty. I havent heard of anyone else having the problem either. A lot of guys on here use the autospring kit from ebay. I used to use the daystar 2" kit. My brother and a few friends have used the Tuff Country 2" in the past. I just installed a 2" Tuff Country on my brother-in-laws truck 2 weeks ago.

 

I've got the 1" Daystar on mine, just wanted to beef up the looks a little, and installed Airlift bags as well to keep the factory rake and to help with rearend sag when loaded. No problems at all with the Daystar. Make sure whatever spacer you use, to get a front end alignment after. Everything on mine stayed spec, except for the toein being slightly out.

 

Thanks for the input I will check on a Daystar
