Ferrea Competition Plus Valves have built a reputation as the industry's most reliable extreme duty valve. To manufacture the valves we use special aerospace quality alloys, including the EV8-Z18, which provides high tensile strength. An exclusive two-step slow forging process ensures proper grain flow and virtually eliminates any damage to thematerial structure. The valves are then heat-treated and stress-relieved over a 48-hour period, which is the crucial base of our molecular integrity. These valves feature avionics-quality hard chrome along with a specially applied hard tip.

These high performance clutch plates from Sachs are a direct replacement for an OEM clutch plate and have a much more aggressive friction surface which allows them to handle up to 40% more torque. This makes them ideal for competition cars where a more aggressive clutch actuation is acceptable. For these clutch plates to operate at their maximum torque capacity they should be used with a Sachs high performance clutch cover.
