Skunk2 Ultra Series Valve Springs for All Imports

Each set comes complete with all valve springs for your engine.

Skunk2 Ultra Series Valve Springs have been developed as a result of many years of experience in drag and touring car racing. The Ultra Series springs are made from super clean, Japanese milled chrome silicone wire, shot peen stress relieved, and heat treated to provide consistent and reliable performance. All Skunk2 valve springs are race tested and proven and can be used with both forced induction and naturally aspirated engines. Skunk2 Recommends these Ultra Series Springs for use with most high-end cams, including the Skunk2 Ultra Series Camshafts. You simply won't find better valve springs than these!

The Skunk2 Ultra Series valve spring kits are best suited to be used with the Ultra Series camshafts. In some cases, these are required for proper operation. Providing a high tensile strength, these valve springs ensure valve float is not an issue with even the most aggressive camshafts.

Spring Base Kit Notes: For some applications (when needed), a Skunk2 Spring Base Kit is included for long-term reliability of your camshafts and valve springs.
