TA’s Stage 1 series valve springs are made from high quality chrome-silicone steel and are a direct replacement for stock valve springs. These springs work with stock retainers and keepers yet provide the additional spring pressure required for larger street cams and extra rpm.

•  Use stock or TA 1449 retainers
• Guides will have to be cut for smaller O.D. seals or dampener spring must be removed
• Use TA 1452.040 Locater on Aluminum heads
