Zero Domain CNC cylinder head aluminum 6063

👉 High-quality machined cylinder head with two sealing O-rings for better sealing and centering of the head in the cylinder.

👉 The enlarged nose diameter of 5.4mm (similar to the EPES Extra Fit cylinder head) reduces nozzle movement and thus helps eliminate mid-cap syndrome, for example.

👉 Thicker piston impact rubber for quieter operation, while (in most cases) eliminating the need to use AOE pads.

👉 The rubber cushioning insert between the piston and the gearbox face absorbs shocks and reduces the risk of gearbox rupture. During installation, check that it does not block the movement of the nozzle arm; if necessary, the cushioning insert can be removed and shortened. The inserts can also be removed completely.
