PROX Valve Stem Seal - Manufacturer's ref: 35.VS024
An essential wear part for maintaining the sealing of the upper engine on quads and roadsters, this PROX valve stem seal is sold individually. Designed to prevent oil from rising along the valve stem, it helps limit exhaust smoke and deposits in the combustion chamber when in good condition.
