Description
Precision ignition timing is non-negotiable when you’re building a high-performance engine, and the advance curve is where theory meets real-world horsepower. This spring kit for PTX Billet Distributors lets you dial in the exact advance characteristics your engine demands, whether you’re optimizing for a naturally aspirated build or managing boost pressure under forced induction. Control your timing curve, control your power delivery.
The Advance Spring Kit is a straightforward bolt-on solution that replaces the stock spring assembly in your Pertronix distributor, giving you the ability to fine-tune mechanical advance without expensive dyno tuning or guesswork. If you’re serious about extracting consistent performance from your engine, this is a fundamental upgrade.
