Dual Spring Kit – Made in the USA, Includes Retainers & 10° Locks
When higher RPM, greater valve lift, stiffer spring pressures, and larger valve sizes exceed a single spring’s capabilities, it’s time to upgrade to a dual spring setup. Our American-made Dual Valve Springs provide the extra control you need, maintaining precise valvetrain motion and safeguarding against valve float.

DIY Valve Seal Upgrade:

- Modify your head to use Comp Cams 519-16 seals by employing a Howards Cams Cutter (part #92035)and 5/16″ arbor (#92085).
- The modification is quick and easy—usually under five minutes with a cordless drill.
