Aluminum knuckle arm for Summit

This alloy front/rear knuckle arm is an aftermarket replacement designed for TRAXXAS SUMMIT chassis, supplied as 1pr and finished to fit stock steering assemblies. It serves as a direct replacement part intended to restore or maintain steering link geometry and suspension behavior on scale off-road vehicles.

The component's alloy construction aims to offer a balance of rigidity and wear resistance compared with standard composite parts, helping to reduce flex under load and preserve alignment during aggressive driving or track use. Fitment requires checking pivot clearance and existing hardware alignment, and it works alongside standard bearings and suspension links.

Is this knuckle arm compatible with all TRX Summit models?

It is specified for TRAXXAS SUMMIT chassis; confirm your Summit variant and existing hub dimensions before fitting to ensure bolt pattern and pivot sizes match.

What does alloy construction change compared to plastic parts?

Alloy reduces component flex under load, which helps maintain steering geometry and can improve durability at the expense of slightly increased weight relative to composite parts.

Are any modifications required for installation?

Installation is typically direct, but check for interference with existing suspension links, confirm pivot clearances, and re-check wheel alignment after fitting.

How should I verify the new knuckle arm after fitting?

Verify smooth steering rotation, check for binding at full travel, and inspect mounting hardware torque; confirm suspension travel remains unobstructed.
