Each set comes complete with all retainers for your engine.
Skunk2 Racing Pro Series titanium retainers are the best retainers offered from Skunk2. The Pro Series retainers are CNC-machined from the strongest aerospace quality titanium and are designed to significantly reduce overall valvetrain mass. Reducing weight improves power, helps limit valve "float" and promotes valvetrain stability during high RPM conditions. Approximately 42 percent lighter than Steel OEM retainers, these titanium retainers are the perfect compliment to Pro Series Valve Springs and Pro Series Camshaft Upgrades. Skunk2 Racing retainers are machined to extremely close tolerances and inspected using strict quality control standards to ensure superior quality and maximum performance gains. All Skunk2 titanium retainers are manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to ensure that each is optimized for strength as well as for reduced weight.
