300ex front spindles, brakes and hubs on 400ex arms

[YZ400EX]

I am thinking of putting my old 400ex a-arms onto the 300ex, but want to know if the 300ex spindles n such will bolt up to the 400ex arms or will I need to use the complete 400ex front end?? anyone??

The spindles and all will bolt up. The brakelines will reach fine also. Swap out the a-arms. You'll want either custom made shocks, or 400ex shocks and a relocator bracket. The better setup would be +2 300ex a-arms, the 400 arms add a lot of bumpsteer.

yea I know about the whole bigger shock thing and will use the 400ex shocks too because I already have one of those brackets. I just wanted to make sure that everything from the 300ex would bolt up to the 400ex arms..Thanks for clearing that up..

if you can use the 400 spindles i would because they are aluminum, and the 300 are steel, it would save some weight on the front end

I dont care about weight..I already have 300 ex stuff so thats what I will need to use
