This valve collet secures the intake and exhaust valve in the cylinder head of a Citroën 2CV engine. The part keeps the valve stem in a fixed position in relation to the valve spring and spring retainer. The valve collet distributes forces during opening and closing of the valves. This supports stable gas exchange in the combustion chamber. The dimensions correspond to the layout of the original engine components. The material is designed for long service under changing temperature and load conditions in engine operation. Correct installation supports the function and service life of the valve train system.
