Anyone tried crosslinking the rear suspension? Then when you're offroading you could install a solenoid valve that would activate in low-range that would allow air between the sides to flow freely. I'm told if you do this you need to keep the swaybars though to keep things upright. I'm curious about the pros and cons of swaybar removal vs crosslinking. Anyone tried?

 

Do you no longer like your truck? Seem to be going through a lot of issues and potential changes on it. As for your question, I wouldn't even try what you are suggesting. The SLS is processing angles and loads in millaseconds keeping your truck level.
With all the wheeling I have done with my 99 which has the SLS and ACE, I wouldn't change a thing to try and improve it other then to find some longer shocks.

 

Thinking about things doesn't mean they're a good idea or that they're likely. Sometimes it's just an exercise to see if an idea has any merit at all. It's not always 'support' sometimes it's just fun discussion... I hope.
