Ferrea Single Spring Pro CNC 7 Deg Tool Steel Retainer - Set of 16

If you're rebuilding the top end of your engine, especially for performance applications, you'll need strong retainers to keep your valve springs in place under high stress. These Ferrea Single Spring Pro CNC retainers are made from tool steel, a well-built material known for its hardness and durability, which is crucial for handling the forces involved in engine operation. The 7-degree angle is a common specification that ensures proper seating with many valve guides and seals.

Ferrea machines these retainers using CNC processes, which means they are made with tight tolerances for a consistent fit and reliable performance. This set includes 16 retainers, enough for a typical 8-cylinder engine. Using high-strength retainers like these helps ensure your valve train operates smoothly and prevents potential damage that can occur if components fail under load.
