Does anyone have any tips on maintenance for a suspension lift kit? I browsed around and couldn't find any threads on it, so I figured I'd ask. Any help would be great

 

Assuming its a 5 or 6 inch lift your talking about then you need to periodically re torque all bolts in the lift as well as keeping plenty of grease in all your joints. Check to make sure that the lift hasnt shifted towards the diff and make sure the drive line still has the acceptable clearance
