Ben,
They look shiney, but its doubtful they'll help improve your car's performance, handling or top speed at all. if your stock plastic shocks aren't leaking there's not need to worry about them; if they are just replace the o-ring gaskets and be done with it.
About the only "mod" the factory plastic shocks could use are replacing the brass pistons with the plastic OEM buggy ones; and even that's debatable since Jlock has been whipping people's butts with those stock brass pistons for years. Lol
Want to really increase the high speed performance & handling of your Kyosho?
Get yourself a Warrior GT body and give it a try.
Good luck, hope it helps.
