The Sea-Doo Rocker Arm Stretch Bolt Set from SBT is a high-quality replacement hardware kit designed for all Sea-Doo 4TEC engines manufactured between 2002 and 2022. Engine rebuilds and major maintenance procedures require reliable fastening components, and replacing used stretch bolts is an important step in ensuring long-term engine performance and durability.
This kit, SBT part number 75-112-02, replaces OEM part number 420641080 and includes six rocker arm stretch bolts (M8 x 72). These bolts are specifically designed to provide the correct clamping force required for proper rocker arm installation and valve train operation.
Stretch bolts are engineered to elongate during installation to achieve precise torque specifications. Once used, they can lose some of their original strength due to repeated engine heat cycles and operational stress. Measuring a used bolt does not accurately determine the amount of strength that has been lost over time.
Installing a new Sea-Doo Rocker Arm Stretch Bolt Set during engine rebuilding or cylinder head service helps maintain factory-specification performance and provides added confidence in the reliability of your repair.
