Boom Racing Brass Knuckle Weight System For BRX70/BRX90 PHAT Axle
Boom Racing releases modular brass weight performance upgrades for their BRX70 and BRX90 PHAT axles.
Add non-rotational weight mass onto the axle for better stability and traction control. Adding weights strategically on a crawler will increase performance drastically.

- Weight: 76 grams total
- Rear Knuckle Base Weights for BRX70 Axle #BRLC7090
- Weight: 88 grams total
- Rear Knuckle Base Weights for BRX90 Axle #BRD9024

- Weight: 23 grams each
- Small Weight Block (2) #BRLC7092

- Replacement Lock Ring (2) #BRD9024A
These new parts are made from high-grade brass and anodized in black color with machined edges. This is a complete modular weighted system which means they can be installed in multiple ways for different setups to suit your needs.
The name "Knuckle Base Weight" probably already reveals what it is, besides adding weight to the axles, they double as a base for extra brass Weight Blocks to be added.
These extra Weight Blocks can be installed separately as well as combined together as a whole for an extra weighted setup. For example, they can be added just on the bottom half which is close to the lowest point of the vehicle (for the lowest center of gravity).
- Most 1.55" wheels and up
Note: The Large Brass Weight Block will only fit 1.9" wheels and up.
