      Racers, lock and load for Operation Full Throttle with Tool Room RAD racing valve springs from Isky. Utilizing failsafe endurance processing, every part and every batch is tested every time to give you the ability to push your engine to the limit! The RAD-9000 processing of Tool Room valve springs employs radial densification (RAD), Isky's trade secret, to optimize the physical properties and endurance of your engine's high-rpm torture as you battle for the checkered flag. These precision-designed, "super-clean," high-alloy steel racing valve springs are put through an all-out, no-holds-barred endurance test. The elite survive this pass-or-fail benchmark, ensuring that only the strongest go into your race car. Ordinary valve springs can succumb to resonant vibration, putting you out of the race.
