Alloy knuckle arm built for Summit performance

This front/rear alloy knuckle arm is an aftermarket replacement tailored to the TRAXXAS SUMMIT chassis, supplied as 1pr and machined to fit standard steering assemblies. It acts as a direct swap to restore steering link geometry and keep suspension behaviour consistent on off-road machines.

The alloy material offers greater rigidity and improved wear resistance compared with many stock composite pieces, helping to limit deflection under load and retain alignment during demanding runs. During installation, verify pivot clearance and confirm existing hardware alignment; the part mates with conventional bearings and suspension links.

Will these knuckles fit a modified Summit with aftermarket hubs?

They fit stock Summit hubs; if your vehicle uses aftermarket hubs, compare bolt patterns and spindle diameters before fitting to ensure proper match.

What are the main benefits of alloy over plastic knuckles?

Alloy provides reduced flex and better long term wear resistance, which helps keep steering geometry stable during heavy loads, though it may add a little weight.

Should I retorque fasteners after first runs?

Yes, retorque and recheck hardware after initial break-in runs to ensure nothing has loosened and pivot clearances remain correct.

Are these suitable for scaled trail rigs as-is?

They are suitable for scaled trail use when installed correctly; confirm fitment and check for any interference with tyres or shocks on heavily modified rigs.
