The MAHLE JV1690 Rear Main Seal Set is a direct replacement rear main seal set for 2003-2018 Dodge Ram and Ram trucks with the 5.9L or 6.7L Cummins. It is made to stock specifications from OE quality materials, and it comes with RTV sealant, so the job is covered once the back of the engine is open.
Fitment
MAHLE lists the JV1690 for these Cummins engines:
- 2003-2007 5.9L Cummins common-rail
- 2007.5-2012 6.7L Cummins
- 2013-2018 6.7L Cummins
That covers Dodge Ram 2500 and 3500 pickups through 2009 and Ram 2500 and 3500 pickups from 2010 to 2018. The 6.7L also went in 3500, 4500 and 5500 chassis cabs, which use different frames and some different hard parts, so chassis-cab owners should verify fitment separately. On 2013-2018 trucks, High Output engines behind the Aisin automatic use some different gasket part numbers than 68RFE and G56 engines. Match by transmission and HO status, not just the year. Verify fitment by VIN or call us.
Why this part
One set covers three Cummins generations: the 5.9L common-rail and both generations of the 6.7L through 2018. MAHLE describes it as the replacement for the main bearing gasket on these engines, made to stock specifications as a direct replacement. It maintains factory performance and is built from OE quality materials.
The design is simple. The seal is a one-piece rubber seal, the gasket is paper, and RTV sealant is in the package. You are not hunting for sealant or a separate gasket once the rear of the engine is apart, and you are putting back the same style of seal the engine left the factory with.

About MAHLE
MAHLE began in 1920 as a small engine shop in Stuttgart, Germany, and pistons made its reputation. Its sealing line now runs from head gaskets and complete engine gasket sets to valve cover, oil pan and timing cover gaskets, next to the pistons, rings and bearings diesel shops have used for years.

Frequently asked questions
Do I need to buy sealant separately?
No. RTV sealant comes in the package with the paper gasket and the one-piece rubber seal.
Does it fit my 2013-2018 High Output 6.7L?
The JV1690 is listed for 2013-2018 6.7L Cummins trucks. High Output engines behind the Aisin automatic use some different gasket part numbers than 68RFE and G56 engines, so send us your VIN and we will confirm before you order.
Will it fit a 1998.5-2002 24-valve?
No. This set is listed from 2003 on. MAHLE lists the JV1622 set for 1989-2002 5.9L Cummins engines.
