MAHLE Original American Motors Ambassador 74-67 Rear Main Seal Set

If you're rebuilding the engine in your American Motors or Jeep vehicle, a rear main seal is a critical component to get right. This rear main seal set from Victor Reinz is designed to replace the original seal, helping to prevent oil leaks from the back of the crankshaft where it meets the transmission. A properly sealing rear main keeps oil where it belongs, protecting your engine and transmission from contamination and ensuring your engine runs smoothly.

Victor Reinz is known for making well-built engine gaskets, and this rear main seal set is no exception. It's made to meet the original specifications for fit and function, so you can be confident it will install correctly and perform as expected. This seal is a key part of keeping your engine's oil contained, especially in classic American Motors models like the Ambassador or Javelin, and Jeep vehicles like the CJ or Wagoneer.

When you're tackling an engine rebuild or repair, using the right parts makes all the difference. This rear main seal set is a solid option for many American Motors and Jeep applications from the 1960s through the early 1990s.
