Tamiya 15515 Short Mass Damper Block (6x6x14mm/2pcs.)

Mass dampers are a common upgrade for Mini 4WD cars. They add stability by helping to absorb impacts after a jump. This set expands the line-up of mass dampers with smaller (14mm long) block weights than were previously available, giving you more setup options to take on tricky circuits. At 3.6 grams each, they are 4.7g lighter than 6x6x32mm blocks.
