I have an 03 FX4. Is there anything I can do to improve the handling w/o compromising the truck's suspension, off road capabilities, etc? I have heard of throwing on the Lightning antisway bar, would this make a difference, and what would the installation entail?

 

I'm not sure, but better shocks will help.

 

I have a rear sway bar on mine, got it from summit. It made my truck feel 100% better. Tight and much more responsive

 

Sway-bar, traction bars, "street-oriented"/performance shocks...
