In the past, new updates have been put in as rolling changes to the current part #..

The eight 2.0 has evolved over time to include many of the new style parts, such as ball cups and brake pads.

If they do something similar for the shock tower on the truck, it will most likely not be introduced as a new kit, so you would be rolling the dice on how long it would take for hobby shops /distributors to filter through the old stock.

I'd say, just buy a kit and upgrade it when you can/ if you feel neccessary.
