What material are these spring seats made from?

These spring seats are made from hardened steel. This material is chosen for its ability to withstand the high spring pressures and RPMs found in performance and race engines.

Do these spring seats require cylinder head machining?

No, these ID spring locators are designed to avoid extensive cylinder head machining. They feature an internal locating shoulder, making installation simpler compared to older external cup designs.

What is the purpose of the shoulder on these spring seats?

The shoulder on the inside of the seat serves to center the locator and securely hold the valve spring in its proper position. This prevents the spring from shifting, which is crucial for consistent valve train operation.

Product Details

These COMP Cams ID Spring Seats are made from hardened steel, a solid choice for engines that see high RPMs and extreme spring pressures. Traditional shims can struggle under these conditions, but these locators offer a better solution. They feature a shoulder on the inside that centers the seat and securely holds the valve spring in place, preventing unwanted movement.

The design of these seats is particularly helpful because it avoids the need for extensive machining in the cylinder head. Unlike older designs that required the head to be machined to accept an outer cup, COMP Cams' ID locators have the locating shoulder on the inside. This means they fit right in and do their job protecting the head and the shim underneath, while keeping the spring perfectly positioned.

This set includes 16 locators, each with a 1.550-inch outer diameter and a 0.570-inch inner diameter. They are designed to work well with a variety of COMP Cams valve springs, including popular part numbers like the 950, 954, and 26955 series.
