COMP Spring Seats - .120 X .780 X .878 X 1.253 Hardened Steel Race Performance

Serious engine builders and performance enthusiasts, these COMP spring seats are exactly what you need when you're building for high-RPM performance! The dimensions are precision-made at .120 x .780 x .878 x 1.253, ensuring perfect fit and function in demanding applications. What makes these seats special is the hardened steel alloy construction - they're built to handle extreme spring pressures and the crazy high RPMs found in today's street and racing engines. Older style standard shims just can't compete with the durability and stability these provide. I've used these in several performance builds, and the difference in spring stability at high RPM is noticeable immediately. The quality is typical COMP Cams - professional grade and reliable. Whether you're building a drag race engine, circle track motor, or just want the security of knowing your valve train can handle whatever you throw at it, these spring seats deliver the performance and peace of mind you need. The installation is straightforward if you're familiar with engine building, and they fit precisely as specified. In a world where every component matters at 7,000+ RPM, having spring seats that won't fail under pressure is absolutely crucial. If you're tired of worrying about valve train stability or building an engine that sees serious use, these COMP spring seats are definitely worth the upgrade. They're one of those components that might seem small but make a huge difference in reliability and performance when the tach needle is climbing!
