Sold as a set of four in two sizes that can be used in various combinations, these bolt-on weights add weight in one of the most ideal locations. These brass knuckle weights come in at 9.2g and 5.2g (each set includes two of each weight). The machined weights lower your rig’s center of gravity while also placing weight far out from the center of the chassis. This increases side hill capabilities while increasing the overall stability of your rig. Fit AX24 and SCX24. These work with the optional brass knuckles. AXI302003 required for installation.
