These kits are made exclusively by Supertech for the Sea-Doo 4-Tec engines.

Includes 6 OE rocker arm shaft bolts that MUST be replaced during installation.

Supertech Dual Valve Spring Kits are an excellent upgrade for Sea-Doo owners who have increased their maximum RPM and want to reduce stress on the engine while improving reliability. All Supertech valve springs are manufactured from premium Superclean Chrome Silicon Vanadium steel alloy, offering exceptional strength, durability, and structural memory at high RPM. Each spring is computer-designed to ensure wire stress remains within safe fatigue limits, while advanced software is used to control harmonics so the springs operate smoothly under extreme conditions. This combination of precise engineering and high-quality materials delivers outstanding durability and performance in demanding racing environments.

The dual-spring design is especially beneficial for performance engines with heavy valve trains. The two springs rub against each other and act as a natural damper, reducing vibration and extending valve-train life. The secondary spring also serves as an important safety feature, helping prevent catastrophic engine damage by catching a broken spring before it can drop a valve. Together, these features give Supertech Dual Valve Springs a serious advantage in both performance and long-term engine protection.
