• This is a set of rear brass knuckle base weights for the BRX70 PHAT Axles. Made from high-grade brass and anodized in black color with machined edges.
  
  The knuckle weight also acts as a base for more brass weights to be added. There are two sets of additional weights available; including large brass weight blocks (2pcs) and small brass weight blocks (6pcs).
  
  Add non-rotational weight mass onto the axle for better stability and traction control. The lower the weight, the lower the center of gravity (CG). Adding additional weight to the lower portion of the vehicle helps lower CG.
  
  Adding this Knuckle Base Weight will not increase track width offset.
