KING OF CRUSHERS 2.0
Twin Vertical Plate Chassis
I designed the KOC 2.0 carbon-fiber chassis to hold the speed control and battery as close
as possible to the truck’s centerline to centralize weight and make the truck as responsive
as it can be. On many trucks, the battery is mounted along the center of the chassis and that
was the direction that I was going to go, but I found that, by doing this, about only a third of
the pack was as low as possible. By turning the battery and mounting it across the chassis, I
was able to get about half of the battery weight as low as possible. ;e battery plate is carbon
fiber and mounted to two square aluminum cross-members. Having 3D-printed stops at each
end allow me to adjust the width for any battery that I put in the chassis, and a Velcro strap
keeps it tight to the plate.
Carbon-fiber plates and 1/4-inch
cross-members make up the
chassis for my truck. All the
weight in it is as close to the
center as possible.
If you’re looking for the best
performance possible, you can’t
have a solid-axle monster truck
and not use a 4-link suspension.
;e Axial Yeti-based monster
truck that I built before this truck
had link-mounted shocks, and I
really liked the feel that they gave
it, so I used the same setup on
the KOC 2.0. I had the lower links
made out of aluminum, and they
use RPM rod ends with Traxxas
aluminum pivot balls. I designed
the links to use screws to attach
the rod ends to the links instead
of threaded rod. ;is way, if I bend
or break a screw, it can easily
be replaced, unlike a threaded
rod setup. I went with Traxxas
Revo turnbuckles for upper links
because they look cool, and it was
one less thing that I had to make. I
have three mounting holes in the
chassis for the upper links. ;e
front links stay in the upper holes
and are, therefore, parallel, while
the rear links can be moved down
to reduce rear traction if necessary.
U-shaped mounts are used to
attach the links to the axle housing.
My custom 4-link suspension consists of custom-made lower
links and Traxxas Revo turnbuckles for upper links.
