STANDARD Axial SCX10 BEEF TUBES From Beef TubesThese are an upgrade for the Axial AX-10/SCX-10 axle housings that benefits the rig in several ways. They add weight down low to help the C.G. on 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. The main benefit is that they give you a solid metal mount for the c-hub screws, instead of the stock thin plastic that normally holds the c-hub screws and strips out easily.They will work in both the front and rear axles.You will receive two Standard Beef Tubes (one axle).Tube weight = 1.6 o.z. per set.These are the Original Standard Beef Tubes. Please DO NOT be fooled by the imitations out there!!!
