Product Details
IMPORTANT NOTE: New sealing rings must be the same thickness or very slightly thicker than the ones currently in your cylinder head. Never install sealing rings that are thinner or the pre-chamber will be set to far into the combustion chamber. When you order new sealing rings it is preferred that you remove the prechambers and measure your old ones first to assure that you get the right size. We DO NOT take returns on pre-chamber sealing rings - so if you order a variety with the intention of hoping you get the right size keep in mind any extras are not returnable.
