Speedmaster 8400 Series Distributors contain the same features as the 8000 Series with the major difference being a mechanical advance system. The 8400 Series Distributors are designed with the advance adjustment located in the top of the distributor. This location is ideal for making mechanical advance changes without having to take the distributor apart.

Features:

• Distributor housing machined from billet 6061-T6 aluminum
• Polished 1/2" steel shaft with Tuftride coating
• Spark plug-type terminals for secure wire attachment
• Extremely accurate magnetic pickup that never requires adjustment
• Adjustable mechanical advance to accurately modify the advance curve

Note: Speedmaster Billet Distributors must be used with a Speedmaster or MSD 6A/6AL Ignition Control & Coil.
