1.536 Dual Valve Springs (16)

The 1.536 Dual Valve Springs from PAC Racing Springs are precision-engineered components designed for high-performance engine builds where valve control and reliability are non-negotiable. These dual valve springs are essential for builders and mechanics working on modified engines that demand superior valve seating force, stability across the RPM band, and resistance to valve float.

Built for everything from street performance applications to track-focused race engines, this 16-pack set provides the necessary components for a complete cylinder head refresh or multi-engine project inventory. PAC Racing Springs manufactures these dual-spring assemblies to maintain consistent valve closure pressure and prevent valve float even under aggressive cam profiles, high lift, and extended RPM ranges.

Serious engine builders, performance shops, and DIY enthusiasts rebuilding heads for forced induction, nitrous, or high-RPM naturally aspirated applications rely on PAC valve springs for their reliability and performance. The 1.536 diameter specification is a common fitment across numerous small-block and mid-block engines, making these springs a versatile choice for both OEM restoration and high-output modifications.
