CNC-friendly alloy knuckle for Summit chassis

This aftermarket alloy front/rear knuckle arm is engineered for the TRAXXAS SUMMIT chassis, supplied as 1pr and finished to match stock steering assemblies. It functions as a direct replacement to re-establish intended steering link geometry and suspension characteristics on scale off-road vehicles.

Manufactured to provide a balance of rigidity and wear resistance relative to polymer originals, the alloy design reduces flex under operating loads and helps maintain alignment during dynamic driving. Installation requires inspection of pivot clearances and confirmation of hardware orientation; the component is compatible with standard bearings and suspension linkages.

What precision checks should I do before fitting?

Measure pivot bore diameters and hub bolt pattern to confirm tolerance match with your Summit assemblies; verify that bearing seat dimensions align with your existing bearings.

Are these knuckles heat treated or surface coated?

Material finishing improves wear resistance and appearance; inspect part notes for specific surface treatment and follow recommended maintenance to retain fitment accuracy.

How should I verify alignment after installation?

Perform static steering sweep checks, confirm free rotation through full suspension travel, and measure track width and toe to ensure geometry remains within expected bounds.

Is any reworking required for high clearance tyres?

High clearance setups should be trial fitted; where necessary, adjust link angles or tyre choice rather than machining the knuckles to preserve structural integrity.
