Well machined aluminium V2 cylinder head with an easily removeable 4mm padded rubber bottom pad. Colours may vary.
Product may need some modification in order to fit. I've found that the round retention holes on either side are a little too small for a very few gearboxes. This is easily fixed with a small file or dremel. The size of the retaining holes on the cylinder head are 4mm so please check your cylinder head notches on your gearbox, anything under 4mm diameter should work fine.
