What are tube chassis made of?

Is a longer wheelbase better for rock crawling?
As for rock crawling, try splitting the difference between a full-size truck and a Jeep with a short wheelbase by going with a Jeep with a longer wheelbase. This gives you the best of both worlds.
Is short wheelbase better for offroad?
There is no definitive number for the best off-roading wheelbase. This being said, a short wheelbase, combined with a suspension lift and big tires, will help you get over more obstacles on the trail. To put it simply, the shorter the wheelbase, the better.
How much horsepower does a rock crawler have?
Many Rock Bouncers are powered by GM crate motors coupled to custom transmissions and transfer cases. Typical power output for these beasts varies between 500 to 750 horsepower (although many now push 1000 hp), and the torque exceeds anything seen on street vehicles.
How can I make my tubes stronger?
Thicker wall and bigger diameter put you in the right direction. The most popular suggestion here is filling the tube with concrete. This no doubt will get you a stronger member that is capable in flexing more and take more load without bucking the top or compression side of the tube.
What is the perfect wheelbase for rock crawling?
Wheelbase 108-117 (Inches): This wheelbase is probably the most common, as far as off-road cars go. Think of things like the 4 door Jeep Wrangler, and even some pickup trucks. While this wheelbase isn’t so big that it makes off-roading hard, it’s just big enough to give you good stability and handling on the trail.
What is the ideal wheelbase for a rock crawler?
If you have the ability to keep the rig low, a 40-inch tall tire is not out of the question, but for the average 4×4, that’s a big investment, both from a financial and build standpoint. A more common, and somewhat happy medium, for this wheelbase is going to stay between 35 to 37 inches.
