GPM ES021 ENDURO SENDERO Trail Truck Front Knuckle Arm 6061 T6 Aluminum  [ES021]

Trail-focused aluminum knuckle arm

This aluminium front knuckle arm is an RC-scale upgrade aimed at stabilising the CVD and sharpening steering feel on ENDURO SENDERO style trail trucks. Fabricated from 6061 T6 aluminum, it aims to keep weight down while offering resistance to deformation under hobby loads. A fitted Delrin collar reduces joint play to give a more positive steering touch without altering factory geometry.

The component installs as a direct replacement using original mounting points and included hardware. Fasteners and lock nuts come with the part for a straight swap-in, so no extra machining is needed. It is intended to boost steering feedback and component longevity for trail use rather than to change suspension kinematics.

When setting up, treat these knuckles as a precision durability upgrade that helps maintain axle alignment under load and reduces subtle play that can hide setup changes. Re-check fastener torque and CVD clearance after installation and follow normal maintenance routines for bearings and threadlocked joints.

A practical hop-up to tighten steering response and protect steering components on ENDURO SENDERO style trail rigs while keeping stock fitment and adjustability.
