guys will this make the kids 300 front any better 4 racing? and will it bolt on easy?

 

You will need to buy a shock relocation mount if you are going to use the 400ex shocks. Diamond J customs on ebay has them for sale, and I do believe there is another place out there that makes them but i dont know their name off hand. Everything else works fine.

 

does it make the 300 front end wider and stronger

 

check your pm i sent you message about it.

 

to make it wider you need to run the 400ex a arms which are stronger than the 300
