you need to compare apples to apples. meaning the same manufacturer shocks. typically manufacturers try to "recycle" as much of the parts as they can, this includes shocks. my HPI proceed shocks are the same shocks as the threaded shocks i upgraded on my super nitro; minus the shock cap, springs, and rod ends of course. Serpent used the same adjustable shocks for their vector, impact, and impulse cars for a while.
I think only the most recent 1/8th scale cars from Mugen and Serpent may use revised, high volume shocks and longer shock shafts. I dont own any Mugen or Serpent cars so i do not know first hand. Kyosho looks like they equip their evolva with the same shocks as their V One R cars.
