Energy Suspension makes parts in 2 colors. Red and Black.
How are these two colors different?

The only difference between the red and black parts is that most Black Energy Suspension parts are Graphite Impregnated.
This serves to help self lubricate the bushings.
The Red parts do not have this characteristic.
Aside from the actual color and the lack of being Graphite Impregnated - the red parts are essentially the same as the black.
