Features & Product Details

Valve springs are one of the most stressed components within the engine. The springs can cycle thousands of times per hour. When high performance camshafts, with their longer duration and higher lift, are installed the stress can be increased even further. Cosworth valve springs are designed to control the valve under these demanding conditions and are wound from high quality steel with chamfered ends to reduce wear on valve train components. Designed to be used with original retainers with no machining required. These are the perfect complement to their range of high performance camshafts with increased seat pressure ensuring maximum performance and durability.

QUESTIONS & ANSWERS

  • Q: RPM LIMIT ??  Caliman2 years ago

    What's the rpm limit of this kit? ??

      A:  These don't have an official RPM limit rating, unless your running a dry sump oiling system you'll spin your bearings before you exceed the limit of these titanium retainers.
