ENDURO SENDERO TRAIL TRUCK Front Knuckle Arm 6061 T6 Aluminum ES021 by GPM  [ES021]

Front knuckle arm upgrade for trail performance

This aluminum front knuckle arm is an RC-scale hop-up made to stabilize the CVD and improve steering control on ENDURO SENDERO style trail trucks. Made from 6061 T6 aluminum, the design balances low mass with tensile strength to resist bending under routine trail use. A pressed Delrin collar is fitted to reduce play at the joint, keeping a firmer steering feel while retaining stock geometry.

The part fits as a direct replacement using the original mounting points and hardware. It ships with the screws and lock nuts required for a straightforward swap-in, so no additional machining is necessary. The focus is on better steering feedback and longer service life for the steering linkages during trail crawling rather than changing suspension travel or steering throw.

Tune these knuckles as a precision durability upgrade: they help hold axle-to-wheel alignment under load and cut down on slop that can mask subtle setup changes. After installation check fastener torque and CVD clearance, and use standard hobby practice for threadlocker and bearing inspection.

Use this knuckle arm to reduce steering play and extend component life on ENDURO SENDERO trail trucks while keeping OEM fit and adjustment options.
