Product Description
MAHLE SS45411A valve stem oil seal set restores OE-level oil control on 1989–1998 5.9L Cummins 12-valve heads. These “old-style” push-on seals fit both intake and exhaust positions and use heat-resistant fluoroelastomer for stable sealing under towing, work-truck and daily-driver heat cycles.

FAQ
Do these fit both intake and exhaust on the 12V?
Yes—SS45411A is a push-on set for both intake and exhaust positions on most 1989–1998 12V heads.
How many seals are included?
Set of six (6) seals—one per valve on a 12-valve head.
What’s the material and why does it matter?
Fluoroelastomer resists heat/oil breakdown for stable sealing and reduced consumption.
How do I know if I need top-hat style instead?
Check your removed seals or head; if your engine used top-hat style, use SS45953.
