Supertech Toyota 3SGTE Dual Valve Spring Kit (Flatten Valve Guide Boss for Inner Spring to 0160in)

This is the Supertech Dual Valve Spring Kit, specifically designed for the Toyota 3SGTE engine. If you're working on a performance build or rebuilding the top end of your 3SGTE, a strong valve spring setup is crucial for keeping everything in sync at higher RPMs. This kit addresses a specific detail for the inner spring, featuring a flattened valve guide boss to accommodate it up to 0.0160 inches. This attention to detail helps ensure proper seating and function, which is vital when you're pushing the engine's limits.

Supertech is known for making well-built valvetrain components, and this dual spring kit is no exception. Using a dual spring design helps manage harmonics and provides the necessary seat and open pressures to control the valves reliably, even under aggressive camshaft profiles and high engine speeds. The kit is designed to work with the specific geometry of the 3SGTE head, aiming for a direct fit where possible. Proper valve control prevents valve float, which can lead to serious engine damage, especially in turbocharged applications like the 3SGTE.

When installing this kit, it's important to follow the manufacturer's instructions carefully, paying close attention to the specific requirements for the inner spring and the flattened valve guide boss. Ensuring correct installation is key to realizing the full benefit of this performance valvetrain upgrade. This kit is a solid option for anyone serious about building a reliable and high-revving 3SGTE engine.
