Single Ring Piston Kit Kawasaki JS440 '77-92

Great customer service

Ordered Piston kit for older stand up jet ski. There is not a lot of outfits that supply pistons but Wossner did. Received parts and they look great although I ended up finding original cast piston in the over sized piston that I needed. Their customer service was great, took return back with no issues. When it comes time to rebore to next size I will be ordering through Wossner. Thanks, Mark Brazee

They look great

Always liked the single ring on slightly modified engines. They are very well made and high quality product.

Wossner or Bust!

Beautiful piston, perfect fitment and good quality rings and pins.. digggg it!
