What is the primary function of these valve springs?

These valve springs are designed to control the movement of your engine's valves, ensuring they close quickly and reliably after being opened by the camshaft. This is crucial for maintaining proper engine timing and preventing valve float at higher engine speeds.

What material are the Supertech valve springs made from?

The springs are made from high-tensile chrome silicon wire. This material is chosen for its strength, durability, and ability to maintain consistent pressure over a wide range of operating temperatures and cycles.

Are retainers and valve locks included with this kit?

This kit includes single valve springs. It is designed to work with your vehicle's factory retainers and valve locks, simplifying the installation process.

Product Details

This Supertech single valve spring kit is built for Nissan Skyline models with the RB25 DOHC 24V engine that uses hydraulic lifters. If you're rebuilding the top end of your RB25 or looking to handle increased camshaft lift and duration, a strong valve spring setup is essential for keeping everything in sync at higher RPMs. These springs are designed to provide the necessary seat pressure and open pressure to control the valves reliably, even under demanding conditions.

Supertech uses high-tensile chrome silicon wire for these springs, which is known for its durability and consistent performance over time. Each spring is precision wound and ground to ensure it sits perfectly in the cylinder head. This kit includes single springs, which are a popular choice for many performance builds where extreme RPMs aren't the primary focus, but improved valve control over stock is desired. They are designed to work with the factory retainers and valve locks, simplifying installation for a mechanic. Make sure to check your camshaft specifications to ensure they are compatible with the spring pressures offered in this kit.

When installing these springs, it's important to follow the manufacturer's guidelines for seat pressure and maximum lift to avoid over-stressing the components. This kit is a solid option for enthusiasts looking to get more out of their RB25 engine while maintaining reliability. Always ensure you have the correct tools for valve spring installation, as improper installation can lead to engine damage.
