What is the diameter of the front sway bar on an 07 F150 4x4? I couldn't find this info from searching.

Thanks

 

Take at a look Summit Racing's site. I didn't find anything for a 2007, but I did find ones for a 2005. The problem is that they have both a 25mm and a 28.5mm listed. I going to guess and say that a 4X4 has a 28.5.
