The Samix Traxxas TRX-4 Brass Steering Knuckle, C-Hub, Portal Cover & Scale Brake Rotor Set combines the Samix TRX-4 Knuckle (SAMTRX4-4412), C-Hub (SAMTRX4-4014) and the Portal Cover/Rotor Set (SAMTRX4-4413C2), and saves you money compared to buying the items separately! Plus, the kit adds 249 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.
