Kawasaki JS 440 550 550 SX Jet Ski Crankshaft Seal Kit

Brand new crank seal kit.

Fits all Kawasaki jet ski 440 550 models.

If you have an older motor / engine, it’s always a good idea to change the crank seals as part of preventative maintenance. Air leaks develop over time through the seals and can cause a lean condition or serious motor damage. Leaking crank seals can also create many symptoms of bogging and power loss, making you think there is something wrong with the carbs or ignition. In many cases it is the crank seals leaking. If you’re not sure of your motor’s history, we always recommend installing a fresh set of seals.

We also have the ThreeBond 1211 case sealant and complete gasket kits available.

International shipping is also available on most of our items. We normally use USPS airmail and rarely have problems; however, we cannot accept responsibility for lost packages, hold-ups at customs, or any other unforeseen circumstances that can happen with international shipping.
