please see the 1974-1978 seal kit that on our website.

We have the other style oil seal kit too in our store if your engine # is lower than #141331.

Some early production 1978 1979 KZ400 engine's used a different style seal kit, which we do have in a different listing on our website. If your engine number is #141331 and HIGHER then this is the correct seal kit for your engine. Often you can just replace the ones that are giving you problems and then do them all if you need a full rebuild down the road. Hard to find item! This is a great item if you just want to replace a few leaking seals, or if you are doing a full rebuild. This is an amazing and complete 10pc engine Oil Seal Kit. The item that we have here is a great and an essential item if you are restoring, riding or racing your now vintage Kawasaki KZ400 Motorcycles.
