CloseThe Samix Traxxas TRX-4 Brass Portal Cover Set is a precision machined portal cover that adds 55 grams of unsprung weight to the front or rear 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.
Plus, when combined with the Samix scale brake rotors (SAMTRX4-6412 - not included) you have the ultimate scale upgrade package that will dramatically improve the look of your TRX-4.
