Lifts and warranty

Question. If I install a front lift, diff drop,carrier bearing drop and rear lift myself does that in any way affect my warranty/extended warranty? Or does work have to be done by a shop?

 

Warranty work will not be covered if they can prove your lift or install broke something.

 

Doesn't matter who does it. Touched parts are out of warranty.

Affiliated items can be argued by the dealer. Like differentials, etc. The change may or may not have caused a specific problem and the dealer may or may not push back on it.

Unaffiliated items like AC systems etc should be fine.
