Améliorez vos ressorts de soupape avec ces ressorts performants conçus et fabriqués à partir de fils de la plus haute qualité, ce qui entraîne une endurance exceptionnelle aux charges élevées produites par les cames de course. Nos ressorts de soupape sont traités thermiquement et soulagés des contraintes pour augmenter les performances du ressort, la longévité et fournir la stabilité nécessaire aux charges et aux régimes élevés. Traité avec un processus de nitruration supplémentaire qui offre des avantages supplémentaires d'une dureté de surface accrue, d'une durée de vie en fatigue augmentée de 32 % et d'une augmentation de 45 % de la résistance au fluage.
Les moteurs diesel modernes fonctionnent avec des tolérances plus strictes, des régimes plus élevés, des turbocompresseurs VGT créant une contre-pression ainsi qu'une plus grande poussée qui peut mettre à rude épreuve les ressorts de soupape d'usine. Le réglage du marché secondaire qui peut permettre plus de puissance, plus de régime, plus de pression peut également être attribué au flotteur de soupape, provoquant des problèmes de contact entre le piston et la soupape. La dernière chose dont on a besoin est un échec dans ce scénario, alors protégez votre investissement avec un ensemble de ressorts destinés à résister aux abus.
