What is the purpose of a spring seat locator?

A spring seat locator, also known as a spring shim or seat, sits between the valve spring and the cylinder head or spring perch. Its main job is to provide a flat, stable surface for the valve spring to rest on, ensuring it's properly aligned and centered.

Why is the thickness of the spring seat locator important?

The thickness is critical for proper valve spring installed height. If the locators are too thick or too thin, it can affect the spring's preload and travel, potentially leading to valve float or coil bind. These are specifically designed to work with the SPR-TS1015 valve springs at 2.85mm.

What material are these spring seat locators made from?

These spring seat locators are made from steel, chosen for its strength and ability to withstand the high temperatures and pressures within an engine's valve train.

Product Details

At 2.85mm thick, these Supertech spring seat locators are precisely machined to fit with the SPR-TS1015 valve springs, ensuring proper alignment and support within your Subaru WRX's EJ20 or EJ25 engine. When you're rebuilding the top end, getting the valve train components seated correctly is critical for reliable performance and longevity. These locators help prevent the valve springs from shifting under load, which can lead to valve float or even catastrophic engine damage.

Crafted from durable steel, these locators are built to withstand the high temperatures and pressures found in performance engine builds. They are designed to work specifically with Supertech's SPR-TS1015 valve springs, creating a well-matched system for your engine. Installing these ensures that your valve springs sit perfectly flat and centered on the spring perch, which is essential for consistent spring travel and preventing undue stress on other valve train components.

This set includes 16 spring seat locators, enough for a complete engine build. Proper installation of these components is key to achieving the intended performance and reliability from your upgraded valve springs.
