4runner Bumper - Design

I was looking for high-clearance bumpers for my 2004 4Runner, and found really cool, really expensive options. They look fantastic, but it’s a lot for a bit of metal. So I wanted to see just how hard it is to design my own.

It’s hard.

I took the bumper off the car, did my best at measurement, made a cardboard template, then re-built the bumper in cad. If it actually fits, I’ll be pretty happy. I wanted to test if this thing could actually handle the winch loads that I’d be asking out of it. The 4Runner is about 4,000 lbs, and it started to deform at over 8,000lbs. I’d like to have more than a double safety factor, but for now, I’ll take what I can get.
