Potential A Arm Mix Up - Please Help 05 - 07 Mixed - Camber issue

[Ex'rMike]

Can you please post upper a arm length from the frame to the center of the ball joint on various years? 05 - 07... I am really thinking I have a 400ex upper a arm on the left side. Everything is straight on this 07 450er.

Thanks
Michael

I have an 07' 400EX. The front mount to center of ball joint was 11.5". The rear mount to center of ball joint was 12.5". Maybe that'll help...

400ex arms wont fit a 450r, the width is different where it mounts. Could be you have an 04-05 upper arm or its bent.

Take a picture.

Nothing is bent. I measure my a arms to the front mount and it measures 13.75, my friends right side is 13.5 and left is 13.25. Camber is off on the left side.... My 07 has 05 arms and spindles. I am not sure what is on his....

Possibly bent spindle or frame then. My 400ex the spindle and arms were fine but the frame was tweaked causing the right a-arm to have the wheel pitched to the inside slightly.

You are positive everything you have is from an 04-05 450r right? Because I just measured my stock 04-05 upper arm and fromt he end of the arm by the ball joint to the middle of the arm (using a threaded rod to verify middle thru the mounting holes) I come up with 13.25.

Thanks. I am not sure what is year of a arms are on this quad. Nothing is bent, but the left a arm is shorter than the right. I just don't know whether to order an 05 or 07 a arm

Well, 04-05 arms are longer by about a 1/4 of an inch vs the 06 and later arms.
