Never tried the Bilsteins, but I have heard good thongs about them. I have a lifetime warranty on the Rancho's. I have connections.

I did the TB crank so I could stuff a 35 on it. The only need for a lift is to fit bigger tires on it. I have as big as I would go without the lift, so I haven't even bothered. I wheel harder than people with lifts and I do just fine. It's more of a cosmetic thing...
