Product Details
Starting with a .060 inch thickness and a 1.300 inch outer diameter, this spring seat from COMP Cams is made from a hardened steel alloy. This material choice is important because it means the seat won't deform or break down under the high spring pressures and extreme RPMs common in performance LS1 engines. Unlike older shims that could fail, this locator provides a solid base that protects both the cylinder head and the shim itself.
The design here is an inboard locator, meaning it has a shoulder on the inside that centers the spring seat and keeps the valve spring securely in place. This is a practical improvement over older designs that required significant machining of the cylinder head. This particular seat, with its 1.300 inch OD, is a good match for COMP Cams valve springs like the 26921 and 26926, ensuring a proper fit for your build.
