I have a 2 inch lift and the 249. I like the 249, so I'm keeping it in there too. When/if it comes time to replace your VC, it's not that expensive of a part to replace and there are some excellent "how to"s on here for the repair. Not that the lift is going to speed the break down of your VC, but just saying.
