Description

1989-1998 Cummins 5.9L Hamilton Cams 103LB Valve Springs w/ Retainers (07-s-002)

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.

Key Benefits

  • Enhanced Valve Control: Eliminate the risk of valve float in high-stress, high-lift applications.
  • All-Inclusive Kit: Comes complete with retainers and 10° locks, ensuring a secure fit and simplified installation.
  • High Lift Compatibility: Engineered for up to .700″ lift—be sure your machine shop sets the correct installed height.
  • DIY Valve Seal Upgrade:
  • You can run these springs without valve stem seals, or
  • 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.

Step up to our Dual Valve Spring Kit for confident, stable valvetrain control in any high-performance diesel build. Whether you’re pushing higher RPM, boosting valve lift, or running more aggressive cams, these springs keep your engine on track for maximum power and reliability.
