Ultracore 2 Axis Spring Arm

$750.00 $399.00

Ultra Core is a two axis spring arm that attaches at the end of an EasyRig, Flowline, Float 3, or Ultra Core Support System. It stabilizes vibrations and motion errors on the vertical axis that comes from walking or running with the rig. It also stabilizes side to side errors in the same scenarios by counter pivoting around it’s center axis.

Ultra Core Spring Arm can take rigs between 1-10 kg, and you can easily fine tune the spring tension without a tool. It works really well for 3 axis gimbals like the Freefly Mövi, MOZA, B-steady or most other gimbal rigs and cages.


How does Ultra Core Spring Arm mount?
Ultra Core Spring Arm mounts at the very end of the Easyrig, or Flowline arm, and the string is routed upwards and through Ultra Core Spring Arm instead of the normal way straight down from the tip of the UltraCore Support System, Float 3, Easyrig or Flowline.

High Quality Materials
The UltraCore Spring Arm is made from CNC machined aircraft grade aluminum for long lasting use.  It’s also beautifully anodized in a matte black finish.  Every part of this unit is precisely engineered with high grade bearings for ultra smooth feedback.
