Supertech Valve Spring Kits for Vauxhall LEH-X20XEV

Each Supertech valve spring kit pairs springs, retainers and seats that are designed to work together, removing the guesswork from a valvetrain upgrade.

Springs are made from premium Superclean Chrome Silicon Vanadium steel alloy with computer-designed wire stress and controlled harmonics, helping prevent valve float with aggressive cam profiles. For the Vauxhall LEH-X20XEV, Supertech offers 2 part numbers, including Performance Dual Valve Spring Kit with Titanium Retainers.

• Premium Superclean Chrome Silicon Vanadium steel springs
