Hey fellas i got a 04 400 outlander 4x4 and am looking at what mods ya'll would do to the bike if it was yours. i haven't seen alot of aftermarket support so maybe ya'll can let me in on what ya'll have done to your own.

the only thing i've done to it is painted the wheels with bedliner and 27" kenda executioners

 

First thing I would do is put on some front and rear bumpers. The XT models OEM bumpers look terrific IMO.

A winch is also a necessity.

I put a couple of cheapo fog lights from eBay on our front bumper that I think look pretty nice.

Hand guards are nice on the trails, and look great as well.

Can't think of much else really....

Here's some pics of ours:

 

ATVMan, looks like you're trying to wake up the fish out there on that hard water! I have an 05 XT just like yours. I have a Kolpin gun rack on the back but I use it mostly to hoss my chainsaw around the compound.

 

Gotta do something during the winter!

 

i do agree with the bumpers. i really like the rear one and almost bought one but i'm just gonna fab one up.
what about some performance upgrades?

 

Not a whole lot to do with the big utes (short of custom work). I bet you could find a slip on pipe, and get it clutched.
