they go in where the dog bones do. right in the end of the outdrive to keep pressure on them so they stay in as you drive and jump and stuff. make sure you have shock limiters inside your front shocks so they don't extend the full way, cause they can extand far enough during a race and there is enough chassis flex that the dogbones will come out. you don't need a bunch in there, go to losi's site and look in there set-ups and see what drivers set-up you want to try and that will tell how much limiter you need.
