    No Matter Your Vehicle, MSD Has the Best Distributor for It

    Billet and Pro-Billet share the same features except the base. Billet models have Dupont Rynite glass-reinforced bases; MSD Ignition Pro-Billet models have aluminum bases.

    Billet Aluminum Housings made in CNC mills form flawless flex-free components that are accurate to within .001" without weak spots or porosity.

    Maintenance-Free Magnetic Pickups trigger MSD ignitions (except crank trigger models). Mounted to the distributor base, the pickup plugs directly into an MSD ignition control & a trigger signal is produced as the shaft-mounted zinc-plated reluctor passes by.

    Shaft & Ball Bearing Guides: MSD polished steel distributor shafts receive a QPQ coating that reduces friction and resists corrosion. Each shaft is guided accurately by a sealed ball bearing located at the top of the housing. At the bottom, an extra long sintered bushing controls the shaft. This combination spins smoothly and delivers consistent sparks even in a 10,000 RPM racing environment.

    Adjustable Mechanical Advance: MSD's adjustable mechanical advance assembly allows accurate modification of the advance curve to match a specific application. The advance plate is stamped and machined from chrome moly, weight pins are staked then TIG welded, and both receive a corrosion-resistant QPQ coating. Nylon bushings are installed to ensure smooth weight movement as centrifugal force advances the timing. The advance assembly is mounted on top of the distributor for easy-to-access adjustment. Three sets of advance springs and four stop bushings are included to set up 24 curves.

    Pro-Billet Ready-to-Run Distributors are ideal upgrades for outdated and/or bulky systems, and they couldn't be simpler: drop one in, connect three wires, and fire up the engine. They come equipped with a gray tach output wire which will trigger a tach or an aftermarket EFI system. Also included is an adjustable Rev Limiter. Their ignition module creates a powerful inductive spark that improves fuel mixture combustion for quick starts, smooth idle, and great performance.

    Compatibility: Except Ready-to-Run and OE models, MSD distributors require an MSD ignition control.

    JEGS Easy Kits are designed by JEGS professionals so you get all the parts you need. Featuring MSD components, Ready-to-Run Ignition Kits include: Pro-Billet Ready-to-Run Distributor, Blaster 2 Coil, Super Conductor 8.5mm Spark Plug Wires, Coil Wire & Spark Plug Wire Separators.
