The GPM TRX4H100F front C-hub, knuckles and steering link set is engineered to reinforce the Traxxas TRX-4 front suspension. Machined 6061 T6 aluminium components increase structural rigidity and provide adjustable mounting positions to refine steering geometry and damper clearance for technical trail use.

The bottom profile of the C-hub is reduced to increase clearance beneath the body, while reworked knuckles change internal gear pitch and raise the axle line by 1.2mm. These geometry changes improve obstacle clearance and allow for finer adjustment of damper position to tune roll control and axle articulation.
Components are CNC friendly in concept and utilitarian in function, utilising 6061 T6 aluminium for strength and weight control. Delrin collars are employed in the locating holes to reduce friction and wear between mating metal components, which supports longer service intervals and consistent steering feel.
