Tamiya Lunchbox Axle Brace. Also fits Midnight Pumpkin, or any CW01 chassis x 2. You will receive 2 anti slap axle braces for CW-01 Chassis tamiya vehicles. This brace prevents the gearbox from slapping during acceleration while still giving it full articulation. This is much better than a 5th shock mod and much easier to install! This will require drilling 2 holes in the lower batter tray. You can use the mount as a template to get the holes in the correct position.
