TRAXXAS 1/10 Craniac Monster Truck Aluminium Front Knuckle Arm by GPM CRA021  [CRA021]

Front knuckle arm for Craniac

This aluminium front knuckle arm is an aftermarket 1/10 scale RC component supplied as 1pr, intended for use on TRAXXAS Craniac Monster Truck models. It is presented as a direct mechanical replacement for the front knuckle assembly where the knuckle links the steering linkage to the suspension upright, and is intended to provide a stable mounting point for wheel hubs and steering linkages.

The part focuses on compatibility with the TRAXXAS 1/10 Craniac Monster Truck platform and on its role in steering geometry and suspension tuning. Installation involves removing the original knuckle arms from the upright and attaching the aluminium unit using the existing mounting points and hardware, verifying steering throw and suspension travel after fitment. No additional tools or modifications are assumed beyond standard hobby tools.

For tuning, this knuckle arm serves as a rigid connection point that can affect steering response and caster behavior when combined with other setup changes such as roll center adjustments, tie-rod length, and wheel offset. Use it with standard 1/10 steering linkages, uprights, and associated hardware that match the Craniac mounting pattern.

Use this aluminium knuckle arm when you need a durable RC-scale replacement for the Craniac front steering assembly, and verify alignment and travel after installation to keep steering and suspension behavior consistent.
