These are an upgrade for the Axial SCX10ii 2 piece axle housing that benefit the rig in several ways. They add weight down low to help the center of gravity of your rig, enabling you to run less rotating weight in the tires. They also "Beef" up the axle housing itself to help keep from snapping the housing in half. This version also has splined ends which will help eliminate the common issue of the C hub spinning on the stock housing. They will work as both the front and rear axles. You will receive one new axle housing with the Beef Tubes pre-installed..
Team KNK Hardware is included! Tube weight = 1.75 o.z. (50 grams) per set
*Due to the machining required on the axle housing to allow the fitment of the Beef Tubes, we will only offer these pre installed in a new axle housing.
