- This is a set of front brass knuckle base weights for the BRX70/80/90 PHAT Axles. Will also work with AR44 PHAT Axle and stock AR44 plastic axle (must use with BRLC7002 or BRLC7002/CA knuckles which are compatible with the AR44).
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 on. There are two sets of additional weights available; including large brass weight blocks (2pcs) #BRLC7091 and small brass weight blocks (6pcs) #BRLC7092. There are multiple ways to add weight using this modular weight system.
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, especially when the weight is added to the front end.
Adding this Knuckle Base Weight will not increase track width offset.
Specification:
- Weight: 38g each
- Outer Diameter: 33mm
- Fits: BRX70/BRX80/BRX90 PHAT Axle (Front)
