The Samix Traxxas TRX-4 Brass Steering Knuckle, Portal Cover & Scale Brake Rotor Set combines the Samix TRX-4 Knuckle (SAMTRX4-4412) and the Portal Cover/Rotor Set (SAMTRX4-4413C2), and saves you money compared to buying the items separately! Plus, the kit adds 167 grams of unsprung weight to the front of your TRX-4, for improved forward weight bias and performance. Unlike other brass parts, these feature a stealthy black finish, with chamfered edges that give the parts an unmatched look that offers a touch of bling to your scaler.
When combined with the Samix brass c-hubs (SAMTRX4-4014 - not included) you have the ultimate brass upgrade package that will dramatically improve the performance of your TRX-4
- Brass knuckle adds 51g per side (102g per pair)
- Brass portal knuckle cover adds 55g a pair
- Better center or gravity and forward weight bias for climbing
- Improved durability and rigidity over the factory parts
- Made of high quality brass and etched with L and R for ease of installation
- Compatible with Traxxas parts
- Black coating to help prevent corrosion
NOTE: The brake rotor is suitable for the standard TRX-4 wheel, and will clear any wheel with greater than 36mm inner diameter but may require wider hubs.
