Product Details

The Edelbrock 12412 Vacuum Secondary Spring Kit provides precise tuning control for vacuum-operated secondary carburetors. This comprehensive kit includes seven different spring rates, allowing you to fine-tune secondary opening characteristics for optimal performance across various engine combinations and driving conditions.

Key Features:

  • Includes 7 springs with varying tension rates for precise tuning
  • Compatible with Holley 4150, 4150HP, and 4160 series carburetors
  • Also fits various Demon carburetor models with vacuum secondaries
  • Allows customization of secondary opening rate and vacuum requirement
  • Helps eliminate bog or hesitation during acceleration
  • Enables optimization for different engine sizes and camshaft profiles

Tuning your vacuum secondary spring ensures the secondaries open at the right time—too light and they open prematurely causing a lean condition, too heavy and they open late reducing performance. This kit gives you the range needed to dial in perfect throttle response.
