The ARRMA NERO 6S BLX Monster Truck Aluminum Front Knuckle Arm by GPM MAN021 is produced from 6061 T6 aluminium to provide a noticeable improvement in steering precision and durability compared with stock plastic knuckles. These arms are designed to limit unwanted movement so steering feels tighter and more predictable. The included delrin collars help maintain smooth articulation while reducing stress on the arm mounting points.
