Heavy duty alloy knuckle for Summit platforms

This aftermarket alloy front/rear knuckle arm is produced for TRAXXAS SUMMIT chassis, supplied as 1pr and prepared to work with stock steering components. Its purpose is to replace worn or damaged hubs while maintaining steering geometry and suspension performance on scale trail and boulder rigs.

The alloy build aims to reduce flex compared with stock composite parts, improving repeatable alignment during demanding runs. Prior to fitment, confirm pivot clearance and that existing hardware lines up; the part is intended to use the same bearings and suspension links as the original fitment.

Will I need new bearings when fitting this knuckle?

It is designed to accept standard bearings used on the Summit; inspect bearings for wear and replace if rough, but fresh bearings are not always required.

Is wheel alignment affected after swapping to alloy knuckles?

Alignment can shift if pivot spacing differs slightly; check toe and camber after installation and make minor adjustments as needed.

Do these knuckles require different maintenance?

Maintain them like any alloy part: keep pivot areas free of grit, check mounting fasteners regularly, and inspect for wear at contact points.

Can I use these for competition crawling?

Yes, they are suitable for trail and light competition use where reduced flex and consistent geometry are beneficial, but always confirm class rules on aftermarket parts.
