This GPM LU4022 rear knuckle arm is designed for the Losi Lasernut Tenacity U4 to boost rear support and reduce flex. Constructed from 6061 T6 aluminium, it helps keep the drive train tracking true under load.
Using high tensile 6061 T6 aluminium ensures a durable replacement part. Delrin collars are provided to achieve close tolerances and cut down on slop for smoother power transfer.
The component is CNC machined into a refined 3D streamline profile that complements the vehicle while prioritising functional clearance and alignment.
