TRX-4 Black Steel Portal Knuckles

Our TRX-4 Black Steel Portal Knuckles help you add weight down low for a better overall COG.
Most drivers will tell you that adding some weight down low is one of the best ways to improve performance in your truck.

These knuckles fit within the stock footprint and are sturdy as hell.
The steel construction and black oxide finish also make them highly realistic.

These covers are compatible with stock Traxxas and Locked Up RC TRX-4 portal covers.
