yep and from the current setup, i went to the Kinwald setup.
From my first Durango (2009) the ball cup are more heavy duty but i had some issues 2 or 3times with the new one.
The CVD pin still unscrewing, so now my CVD have all 2 screw to retain the pin and secure.
I m very happy with this setup, i prefere the plastic side on dirt and alu side on carpet.
Next evo is the carbon fiber chassis and go down 1500gr
and cut the rear brace to add small shocks.
