TopMax ERGAL CNC cylinder head (black PAD)

A specially designed CNC aluminium cylinder head from TopMax with anti-vibration properties. The use of a quad_ring gasket ensures an excellent seal, and an interchangeable rubber PAD (dumper) allows the head to be customised to suit the configuration.

The size and position of the holes in the head, together with the front rubber bumper, ensure a perfect fit to the walls of the gearbox frame. Additional milled holes in the top of the head reduce and mitigate vibrations created during piston impacts, and reduce the risk of cracking the skeleton face.

The head has a replaceable PAD (dumper), and the rubber from which it is made helps absorb shock and vibration created by piston impacts. Its thickness, on the other hand, has been designed to provide excellent AOE (Angle Of Engagement) of the piston on the piston wheel. The diameter of the PAD assists in sealing with the cylinder and the innovative shape provides optimum air flow to the nozzle. Depending on the colour, they are recommended for different configurations.

The kit comes with a PAD of colour CHERRY (Soft) -recommended for DMR-type replicas or those with an ROF of 10-20 k/s or M85-M95 springs.
