The COMP Cams hardened steel spring locators are a set of 16 ID spring seats that secure valve springs using an inboard locating shoulder. Sized 1.285" OD, .805" ID and .135" thickness, they center the spring and hold it reliably in place during assembly. The 1.285" outer diameter is noted as a good match for COMP's 26918 beehive springs for compact valvetrain setups.
