Install these precision aluminium rear knuckle arms on an ARRMA Kraton 4X4 4S BLX to strengthen the rear suspension. Machined from high strength 6061 T6 aluminium, they deliver robust support and long lasting durability. Integrated Delrin collars reduce play for a tighter fit and smoother drivetrain action. The CNC machined 3D streamline profile gives a clean metallic look while keeping weight down.
