Re: How are you getting over the 4" bump?

Our frame's extruded aluminum (30x30 hand cut and welded). We toyed with a mechanized skid plate, treads, etc. In the end, one of the mentors and a student came up with the idea of putting angled braces on wither side of the front wheels.

The first wheel goes up, the skid braces hit and get you up then the rest of the 8 wheel drive takes over. Makes for a bumpy ride but in the end, it works. However you attach it, make sure they've got good welds/attachments and something like teflon on them to make things easier.
