The 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. 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 steering knuckles (SAMTRX4-4412 - not included) and c-hubs (SAMTRX4-4014 - not included) you have the ultimate brass upgrade package that will dramatically improve the performance of your TRX-4.

Features:

• Brass portal knuckle cover adds 182g a pair
• Improve climbing performance and stability with lower CG
• Machined from high quality brass material
• Black finish to help avoid oxidation
• Includes SAMIX 36mm scale brake rotor & caliper for improved scale looks
• More rigid and increased durability
• Direct fit on TRX-4 front & rear std knuckle and SAMIX alum. or brass option knuckle

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.
