When your engine demands the absolute best in valve control, turn to the Iskenderian RAD-9000 Valve Springs. These are not your average street springs; they are professional-grade components designed for extreme racing conditions. Featuring a dual-spring configuration with an integrated damper, these springs provide a massive 550 lb/in spring rate to keep your valves firmly seated, even when running aggressive camshaft profiles at high RPMs.
The RAD-9000 series is engineered to minimize harmonic resonance, a common cause of valve spring failure in high-output engines. The inclusion of a high-quality damper ensures that the springs remain stable, preventing the dreaded valve float that kills power and damages engine internals. With a 1.570-inch OD, these springs are robust enough to handle the high lift and high pressure required in competitive drag racing and circuit applications. If you are pushing your engine to its limits, you need the peace of mind that comes with Iskenderian's legendary engineering. These springs are the ultimate choice for builders who refuse to compromise on quality or performance. Get your professional-grade racing parts at GGCRACING.
