Features: -Plus 4' wider (2' on each side) -Made from 4130 chromoly steel. Unfortunately, when those things freeze in there, its tough getting them out, especially without damaging more stuff, this is why periodic maintenance includes greasing the swingarm bolt and linkages, just so you don't have issues like this, but unfortunately, most people skip this and this is the outcome, every winter the swingarm should come off and everything cleaned and greased with a waterproof grease (I use Maxima Blue Waterproof Grease), it really sucks, but basically, blunt force, lubrication, and heat are about the only possible ways to get it out, if it will not come out with those methods, then cutting is your only alternative. Fitment: These fit all years Honda TRX400EX. I am guessing that it is frozen where it goes into the engine case, just had a issue like this with a buddys 02 CR250, and we tried beating it, spray penatrents, and heat, and ended up having to cut it off carefully where the swingarm attaches, we used a wheel grinder with a very thin wheel so it would do minimal damage, you will need to remove the subframe to get it out of your way, removing the shock will be a must as well, you have to be patient if your going to do this, but once you get the swingarm off, then you can get the remnants out easier, most of it will fall out, it is possible you may have to beat it out of the case, then replace the collar that the bolt sits in in the engine case once you get everything separated, you will need a new swingarm bolt, and most likely a new collar
