Piston Kits & Rings
SBT offers the first jet ski piston to be sold with a LIFETIME WARRANTY against defect. Our pistonsare cast using a high-silicone-content aluminum. Our "standard" pistons are comparable to others' "premium" pistons - anodized on the top surface for better heat resistance and surface strength, graphite coated on the sides to reduce friction between the piston and cylinder and enable efficient break in. SBT's rings are made of chromium-plated ductile iron and are included along with all new wrist-pins and c-clips. The piston and ring sets are available in an assortment of oversizes to accommodate your needs. SBT carries jet ski pistons for a wide variety of manufacturers. Piston design has developed over the last 140 years. Modern engines run hotter, leaner, and more efficiently than ever before. This has required advances in all piston designs, including jet ski pistons. Newer pistons have gone to high tech materials, such as including silicon for temperature stability and strength and coatings on top and sides of pistons to enhance useful life and reduced friction. SBT Jet Ski Pistons incorporate all the most recent design changes:
Piston Ring design has also evolved with the improvements in piston design and engine efficiency:
