You're almost there. The end of a tough race is fast approaching, but to win, you'll need to push your engine to the limit. The tach will read close to 9000 RPM. Such sustained red-line abuse is like sudden death overtime for your valve train. Ordinary roller valve springs will quickly succumb to resonant vibration, putting you out of the race. Only one valve spring can go there and come back alive, every time! Introducing Isky's new RAD-9000™ process option for Tool Room™ valve springs. Under trade secret Radial Densification™ (RAD), the physical properties of Tool Room™ springs are optimized for even greater surface to core uniformity. To insure they'll withstand the tortures of sustained high rpm operation, we subject each batch to the most rigorous real world test standard ever created, SPINTRON-TEST II. It's a no holds barred run as high as 9000 RPM where for over 1,000 miles, race ending competitive abuse is continuously revisited. This pass or fail benchmark is the only test of its kind in the performance industry and every set of Tool Room™ springs conforms to its high standard. So why take a chance on anything else? Run the only racing valve springs with sustained red-line protection. RAD-9000 ™ process Tool Room™ valve springs from Isky. Absolutely the world's finest, and the new standard of excellence in endurance racing today!
