Crane Valve Springs

These valve spring and retainer kits from Crane offer you an easy, cost-saving method of ensuring that your cam is matched with the correct components. The springs will help strictly stock motors by releasing some of the horsepower that the stock components are holding back. They're heat-treated and can be installed in most cylinder heads with no machining.

Crane offers many different dual springs designed to suit a wide variety of applications. They are available in popular diameters for hydraulic, mechanical, and roller cams. Crane dual valve springs are magnaflux-inspected and checked for tension. Use your specific cam application for the exact valve spring.
