COMP Cams ID Spring Seats 1.350 X 515 X

COMP Cams is a well-known name in performance valvetrain components, and these ID Spring Seats are a solid option for anyone building a racing engine today. When you're dealing with extreme spring pressures and high RPMs, standard shims just won't cut it. These seats are designed to protect your cylinder head and the shim itself, while also keeping the spring properly located and held in place.

What's neat about this design is the inboard locating shoulder. Unlike older styles that required significant machining to fit an outer cup, these seats center themselves from the inside. This means a more straightforward installation and a secure hold. They're made from hardened steel, which is important for durability under those demanding conditions. This particular set, the 4869, has a 1.350-inch outer diameter and a .515-inch inner diameter, with a thickness of .130 inches.
