This GPM LU4022 rear knuckle arm is machined from 6061 T6 aluminium to deliver consistent geometry and enhanced hub stiffness on the Losi Lasernut Tenacity U4. The design focuses on precision tolerances for dependable drivetrain behaviour.
Constructed from high tensile 6061 T6 aluminium, the component is chosen for strength-to-weight balance and long service life. Supplied Delrin collars provide controlled bearing and shaft clearance, reducing side-to-side play and aiding repeatable alignment.
Manufactured with CNC milling, the knuckle arm achieves a consistent 3D streamline profile that maintains functional clearances while presenting a clean metallic appearance suitable for performance-oriented builds.
