Placing the cylinder jug side by side with the OEM I can't tell a difference. I wouldn't be shocked to learn these are just remanufactured OEM parts.The machining in the cylinder walls and on the piston is great and the gaskets all seem to be high quality.Time will tell what the longevity is but initial impressions - there aren't any apparent quality issues to suggest there will be issues.
