Cam 5521
directly fits and replaces; 2004-2008 450/501/550, also 2003 650 model. Can be used to speed up the 2001-2003 FE400e (20034201), It is kinder than the 2001-2003 '53' cam 20034253 and less agressive and damaging. It can replace the 20034255 cam used on the 501/550 but must be re-timed by 5d.
Standard off road cam which causes less damage than the older 53 cam....but not by much!
