Mercedes-Benz 300S Piston Sets - Select Year

Quality: OEM
6 Piston Set 87.00mm - 1st Repair Size There is some confusion on this part # due to design change by Mahle. The previous iteration of this design utilized a 4 ring arrangement. The new version uses a 3 ring design. The confusion is caused by the fact that al- though the new version uses 3 rings, there are still 4 grooves that appear to be for rings. THIS IS NOT THE CASE!! The 4th is a compensation groove. Per Mahle this an OEM design, supersedes the original and is an improvement in design . DO NOT RETURN AS A MANUFACTURERS ERROR!!! - 6 Piston Set 87.00mm 1st Repair Size There is some confusion on this part # due to design change by Mahle.
