Isky 7 Deg. Steel Retainers 507ST

Valve spring retainers are critical to maintaining consistent spring pressure and preventing valve float at high RPM—especially when running dual springs for aggressive cam profiles. The Isky 507ST delivers the precision and durability needed for serious engine builds, with chromoly construction that handles the repeated stress of forced induction and high-lift applications without compromise.

This set of 16 retainers ensures you have a complete solution for four-cylinder engines or a full set plus spares for larger displacement builds. The 7-degree geometry is engineered to work with compatible spring seats and keepers, maintaining proper valve train geometry across the full lift cycle.
