will front stock shocks from an 07 450er fit on an 04 400ex
450 shocks on my buddies 400 made the ride height much higher.The 450r, and the 400ex are much the same. If anything the ride height will be lower with the 450r shock. There is a lot of info on the 400ex section on atv riders (not to move people there or anything).
The guy I got my 400ex off of put front and rear 450r shocks on it. The rear resivoir fits facing the motor but you'll have to delete the airbox snorkel. That's how they did it.from what i know which could very easily be wrong. The front 450r shocks are longer then the 400ex shocks, They can be used, but are not a bolt in upgrade in stock form. They need to be reworked (re-sprung and valved) For the 400. And the rear shock won't work because of the Rezzy.
Give nick a call at Jet suspension,
