Construction & Design:

Manley Performance valve springs and retainers are crafted with attention to detail and durability. The springs are wound from high-grade steel alloys that provide excellent fatigue resistance and maintain their tension over extended use. The retainers are precision-machined to ensure a secure fit and reliable retention of the springs during high-RPM operation.

The design focuses on maintaining valve train stability, reducing the risk of valve float or bounce, which can lead to engine damage or performance loss. This kit’s components are engineered to meet or exceed OEM specifications while offering enhanced performance capabilities for modified engines.

Installation & Fitment:

This valve spring and retainer kit is designed specifically for the Dodge SRT-4 engine with .500 inch valve stems. Installation requires standard valve spring compressor tools and mechanical knowledge of cylinder head disassembly and assembly.

These components are direct replacements for the factory valve springs and retainers, fitting the OEM valve train without modification. No cutting, drilling, or special tuning is required to install this kit, making it a straightforward upgrade for experienced mechanics and engine builders.

What's Included:

• 16 Valve springs sized for .500 inch valve stems
• 16 Matching valve retainers
• Complete hardware set necessary for installation (excluding valve locks)
