Key Features:

Manley Dodge SRT-4 valve springs are crafted with performance and durability in mind. Key features include:

• High-quality spring steel construction for excellent fatigue resistance and longevity.
• Precisely wound coils to provide consistent spring pressure and valve control at elevated RPMs.
• Designed to support aggressive camshaft profiles and increased valve lift typical of modified SRT-4 engines.
• Heat-treated and shot-peened for enhanced strength and durability under high-stress conditions.
• Compatible with stock valve retainers and locks for straightforward installation.
• Set includes 16 pieces, covering all valves for a complete upgrade.
• Manufactured to exacting tolerances to ensure balanced spring rates and engine reliability.

Construction & Design:

Manley valve springs are manufactured from premium spring steel and undergo rigorous heat treatment processes to optimize strength and resilience. The springs are shot-peened to reduce surface imperfections and improve fatigue life, ensuring they withstand the repeated stress of high-RPM operation.

The design focuses on maintaining stable valve control during rapid valve movements, preventing valve float and ensuring precise timing. This is critical for turbocharged engines like the Dodge SRT-4, where valve spring failure can lead to catastrophic engine damage.
