Did you decide against building your own cross member? I'd go with the poly clam shells over those fluid filled ones IMO. You could do 2 per side but if you're going to do that, why not use a t bushing and DOM and build your own?

Hi Ryan, glad you dropped in. Haven't given up on building my own xmember. I really just need to position it where I want it to clear trans tunnel and rear rocker cover to firewall and see where things sit. I just don't want to lift it more than Airlift system can do. Are you aware of any Tbushings that are fluid filled? Just hoping to get the advantage of hydraulic damping to take some vibration out.
