Ground Clearance

I am guessing the part that is hanging you up is the swingarm skidplate. Nothing you can really do except run tall tires, or straddle the ruts
 
dont go straight through the ruts, sometimes you cant really straddle them either. Take them at an angle. My local place is 4x4 heaven and i ride a blaster through there, which is fun as hell except theres lots of mud and ruts. Also i run 22's
 
We had to make out trails in the woods so they are like mud holes everywhere but most of the trail are much wider than the blasty so going at an angel isnt really a choice they are just random spots in the path
