Building a heavy duty beam for the baja have seen some beams that got different diameter tube on the bottom thicker wall. If Im looking at this right i need to make bottom tube 2 1/2" .25 wall top tube 2" .125 wall is this right or any better ideas?
Kar Tek also makes a prefabbed beam (1.75") in custom lengths for pretty cheap and then you can just weld it into your chasis. Saves you a lot of work. This is the direction I am going on my Class-5 Unlimited Baja Bug race car. I am also selling my old 1.5" beam foddrill arms, 4" x 4" over-size, 5/8" Link-pins if you are looking for something for a prerunner rather than a race setup. Same with the old Chromoly 10" over beam.
