Front C-Hub Replacement and Tuning

This 28pcs brass front C-hub kit by GPM is an aftermarket replacement set designed for TRAXXAS TRX4 scale trail crawlers. It installs between the front gearbox and the knuckle arms to join the steering assembly, offering a stable platform to change damper height and tilt during setup tuning. The kit replaces the original linkage mounting points and includes hardware aimed at improving durability while enabling multiple damper positions.

Core components include solid brass C-hubs that act as structural elements and ballast, stainless steel king pins to replace the stock plastic pins for firmer pivot action, and a selection of collars and screw lengths to vary damper clearance and mount height. The kit supplies both round and flat head screws so you can build different collar stacks, tune damper angle, and adapt tie-rod installation without fabricating parts.

Installation notes: the assembly fits between the front gearbox and knuckle arms and requires replacing the factory pins and screws. For tie-rod routing the kit uses 3x18 round head screws (2 pcs) to fasten tie rods where the stock assembly tied into the damper; damper mounting screw choices depend on collar stacks - no collar uses 3x14, one collar uses 3x16, two collars use 3x18, three collars use 3x20 - letting you step damper height and angle. Each brass hub also provides about 49g of additional front-end weight per piece when fitted.

For TRX4 builders wanting a heavier, more robust front mount with selectable damper positions, this GPM brass C-hub kit supplies direct-replacement hardware and configurable collar and screw stacks to refine front-end geometry and handling.

What exactly comes in the 28pcs kit?

The box contains two brass C-hubs, four king pins, assorted stainless screws in the sizes shown, and six aluminum collars, totalling 28 pieces ready for installation.

How do I change damper height with the collars?

Stack collars and match the screw length: no collar uses 3x14, one collar uses 3x16, two collars use 3x18, and three collars use 3x20, which steps the damper mounting height and tilt.

Are the king pins stronger than stock?

Yes, the kit uses stainless steel king pins to replace the factory plastic pins, giving a firmer pivot point and longer service life under heavy use.

Will this change my front-end balance?

Each brass hub adds roughly 49g, so they act as ballast. Expect a noticeable change in front-end weight and steering feel when both hubs are fitted.
