I have found 2 different sizes. 30mm and 32mm. How to I tell which one I need? 01 2500 4x4 CTD auto.

Also, what are the best ones to get? I'm looking at Energy Suspension right now.

 

I'm in the same boat, anyone got some info?

Thanks!

 

Mine is 32mm.. Measured with a vernier caliper. It does matter that you get the right size even though it may not seem like it. BTW, get the black bushings, not the red (unless you really like the color). Black has natural lubricating properties.

 

What do I need to measure? The sway bar diameter?

 

Yea that's what I did. Took measurements from several different spots.
