This Delrin outer join is specified for TA05-series chassis and carries part number TA05-IF19. It replaces the outer coupling on a solid axle assembly, using Delrin for a low friction, dimensionally stable contact surface suited to tight axle tolerances.
Fitting requires removal of the wheel hub and outer axle cap to access the original join, sliding the Delrin unit onto the axle end and securing with the chassis original fasteners. No specialised tools are needed beyond standard hex drivers, but careful trial fitting and clearance checks are recommended prior to competitive running.
From a setup perspective this component is chosen to refine rotational smoothness at the wheel interface and to offer a harder, more wear resistant mating surface than softer injection-moulded plastics. Regular inspection for scoring, play or seating issues will ensure consistent handling and drivetrain feedback on race day.
