Isky Racing Cams Tool Room Dual Valve Springs with Damper

Isky Racing Cams Tool Room dual valve springs with damper are race-proven performance valve springs for serious competition engines. Each spring uses a dual-spring design with a built-in damper. This helps control valve motion, reduce spring surge and keep the valvetrain stable at high RPM. Often called racing valve springs, dual valve springs or valve spring kits, they suit solid and roller cam setups, depending on the part number you choose.

Key Features:

• Dual spring with damper: Nested outer and inner springs plus a damper improve stability and valve control under hard use.
• Premium alloy wire: Made from chrome silicon wire with specialized endurance processing for durability under racing loads.
• Tool Room quality: Built to Isky's racing standards and tested for consistency. These are the well-known "Gold Stripe" Tool Room springs.
• Racing-focused design: Developed for high-performance and endurance racing, including oval track and drag applications.
• Made in the USA: Produced by Isky Racing Cams, a long-established name in racing camshafts and valvetrain components.
• Multiple configurations: The line covers a range of spring pressures, rates and lift capabilities to match different cam profiles and engine builds.

Match the spring's seat pressure, open pressure and maximum lift to your camshaft and valvetrain. Larger-diameter springs may need valve seat machining. Choose the specific part number that fits your build. Isky Tool Room valve springs are a durable, high-performance choice for racers who want dependable valvetrain control.
