he Samix Traxxas TRX-4 "Heavy" Brass Portal Cover & Scale Brake Rotor Set is a precision machined portal cover that adds 182 grams of unsprung weight to the front or rear of your TRX-4! This is a great option to increase forward weight bias for improved performance, and adds weight down low to help keep your truck planted on steep climbs.
