My stock plastics are cracking up.What is the best replacement.

 

check e-by motors. There is some brand new factory plastic being auctioned off.

 

Stock plastic for the 400 is cheap. I think I saw it for about 140 for front and rear in dirtwheels. If you really want some nice stuff, go with the fullbore plastic. Although, I hope your pockets are saggin' because that stuff is ex$$$$pensive. You could also buy some cheesy maier. Your choice!!!!!

 

Is fullbore plastic a name brand,where can I get them,how much?

 

It's a brand name. Look through an issue of dirt wheels. You should find a couple people that carry it. I can recommend Legacy ATV, their number is 336-869-4900. They are great people to deal with. I am not sure on actual price. I know they are 100+ for each piece.
