What Owners Say
Owners and enthusiasts recognize these dual valve springs as serious high-performance components, with documented capability supporting over 800 horsepower and 10,500+ rpm operation across multiple applications. The primary benefit highlighted is preventing valve float at extreme engine speeds, making them essential for high-revving builds rather than mild street setups. Some installers note the stiffer dual-spring design requires proper compression tools—stock removal equipment may not provide adequate force for reinstallation. The reduced mass compared to older DSM springs when paired with lightweight titanium retainers is frequently mentioned as an advantage for controlling valvetrain dynamics. Supertech's proven track record in demanding motorsport applications has established these spring kits as a trusted choice for serious engine builders.
