COMP Cams Spring Seat Cups 1.740

COMP Cams is well-known for making performance valvetrain components. If you're building a high-performance engine that will see serious RPMs, you know that stock shims can struggle under extreme spring pressures. These valve spring locators from COMP Cams offer a simple but effective way to handle that stress.

These aren't just simple shims; they're made from a hardened steel alloy. This strong material protects both the cylinder head and the shim underneath, while also ensuring the valve spring stays properly located and seated. COMP Cams has updated their design to include an ID locator with the locating shoulder on the inside, making them easier to install without extensive cylinder head machining compared to older designs.

This set includes 16 locators, each with a 1.830-inch outer diameter and a 0.640-inch inner diameter. They are 0.060 inches thick, designed to work with a variety of COMP Cams valve springs and handle the demands of racing engines.
