Team Associated ENDURO SENDERO TRAIL TRUCK Aluminum Front Knuckle Arm by GPM ES021  [ES021]

Aluminum front knuckle arm for trail trucks

This aluminum front knuckle arm is an RC-scale upgrade designed to stabilize the CVD and assist steering on ENDURO SENDERO style trail trucks. Constructed from 6061 T6 aluminum, the part balances low weight with tensile strength to resist deformation under typical hobby loads. A hand-inserted Delrin collar is included to reduce play at the joint, maintaining a firmer steering feel without changing your stock geometry.

The component is intended as a direct replacement hop-up that uses the original mounting points and hardware. It is provided with the fasteners and lock nuts needed for straightforward swap-in; no additional machining is required. This part is focused on improving steering feedback and longevity of the steering linkage under trail usage rather than altering suspension or steering throw.

When tuning, treat these knuckles as a durability and precision upgrade: they help keep axle-to-wheel alignment stable under load and reduce slop that can mask small setup changes. Check fastener torque and CVD clearances after installation, and use established hobby practices for threadlocker and bearing inspection.

Use this part to reduce steering play and improve component longevity on ENDURO SENDERO trail trucks, while retaining stock fitment and adjustability for further setup work.
