What is the measurement of the front and rear track shocks on both for an Edge chasis?

I am being told the pro-x shocks work on and edge chasis and I am told they are different sizes? Anyone Know?

I am going to upgrade, I just don't know which way to go.

Thanks for reading.

the fronts skid shocks are very close in length. The rear are total different. The edge rear is a couple inches longer. I would measure for you but it is pointless. It will not work.
