Loren Kispert is the shop foreman for Zumbrota Drivetrain in Zumbrota, Minnesota. He tells us that Mud-Evil is all about function.  Center and higher seating position for visibility out both sides.  The main goal of the build was to make the rig lightweight and weight balanced.  The weight is 51% front and 49% rear.  People often ask how I keep from breaking the axles after they see me beat on it, I tell them it is a combination of being light, having soft compliant suspension and large, soft sidewalls on the tires.  These all act as a shock absorber to protect the driveline.  Minnesota wheeling is mostly mud and snow with a few trails thrown in.  My favorite place to wheel is a local, privately owned swamp.  While Mud-Evil won’t win any beauty contests, it will go across a swamp with ease.  My favorite mod is my one-off billet aluminum transfer case that uses Profab quick change gears.
