    B&M Adjustable Vacuum Modulators let you adjust your shift points within a 2-4 mph range. With a gold iridited finish and an O-ring seal to stop leaks, they will look as good as they work. Comes supplied with pre-adjusted, normal shift points.

    Features:
  • Fully Adjustable
  • Allows You To Tailor Shift Points
  • Comes Supplied With Pre-Adjusted Shift Points
  • Note: If your engine does not make adequate vacuum you will not be able to make the stock or B&M modulator work properly; usually resulting in late, hard shifts.
