New 4-Stroke Cylinder Heads for Sea-Doo & Yamaha
SBT's Brand new Cylinder Head Program allows you to switch out your 4-stroke head at a reasonable cost.
Complete heads come with new SBT parts, proven parts that we have been selling individually for years.
Our new castings are the result of 2 years of development, both in the dyno and on the water for 100’s of hours. Together they allow you to purchase a brand new head that you can bolt onto your engine with no core required.Bare heads come with the seats and valve guides already in and cut.
You can rebuild to your head using the parts you have on hand or order the parts you need individually from SBT.
