Need some help

[neece]

The stock plastic CVD's on my Nitro Rustler suck.......the axle for my rear tire shreds completly out after a few days of running. These are extended arm conversions from Fast Lane...I cant find CVD that are long enough, a friend recommended that Revo or Jato MIP CVD's would be long enough, but i'm doubtful. If some of you guys could do some measuring of any CVD's you may have, and see if measurements are anywhere close to the Image below...3 1/8 inches
