ok so all kinds of parts for the two are innerchangeable. so question is , will a 300ex axle fit on a 400ex? befor you ask me wtf would i do that. g-force makes a axle +2 +4. well it's on back order till the 4th of next month, and that's if it comes in! then the hole 3day ship. as for the 300ex it's instock +2 +4 beein how the 300 is only 2inches smaller in width. if i got them to ship me a 300 axle put it on the 400. then did the +4, given me +2inches wich is all i wanted anyways. write back pleaze big 4wheeling event comen up and i need the dang thing ready!

 

won't fit

 

thanks
