MSD Advance Kit for Billet and Pro-Billet Distributors with Springs and Bushings 8464

If you're running an MSD Billet or Pro-Billet distributor, the mechanical advance curve directly impacts your engine's ignition timing across the RPM range. This advance kit gives you the tuning flexibility to dial in the exact curve your engine needs—whether you're chasing peak horsepower on the dyno or optimizing street drivability. Without the right advance curve, you're leaving performance on the table and risking detonation at critical RPM points.

The MSD 8464 Advance Kit supplies a complete assortment of springs and advance limit bushings, allowing precise adjustment of mechanical advance characteristics. This is essential for engines with modified cam profiles, different fuel octane ratings, or specific boost levels where factory advance curves fall short.
