MSD's Pro-Billet distributors share the same CNC machining techniques as the rest of the MSD distributor line. They feature a housing that is machined from high-quality 6061-T6 aluminum for durability and show-quality looks. Their oversized shaft receives a QPQ coating for friction reduction and corrosion resistance, with the added strength of two sealed ball bearings that guide the 0.500 in. shaft accurately at well over 10,000 rpm. An extra-long sintered bushing replaces the ball bearing at the bottom of Chevrolet models. TIG welded on top of the polished steel shaft is MSD's accurate mechanical advance assembly. The weights are supported by nylon pads that allow the advance to operate smoothly throughout the rpm range. For all-out racing, the advance mechanism can also be easily locked-out. To accurately trigger the ignition, a high-output magnetic pickup is bolted to the base. This pickup produces a precise trigger signal that will never vary more than 1 degree at any rpm. A durable gear is installed for performance applications, and an MSD red cap with brass terminals and race rotor is supplied. They're available in standard and small diameter models for applications with limited clearance, and require the use of a separate ignition box such as an MSD 6, 7, 8, or 10 Series ignition.

These Pro-Billet Ready-to-Run distributors from MSD are the perfect upgrade for weak OE electronic distributors, outdated points distributors, and large HEIs or DuraSparks. All that is required is to install the distributor in the engine, and connect three wires and the coil! A maintenance-free magnetic pickup accurately triggers this ignition with increased output from the amplifier, easily outperforming stock ignitions. It will smooth out the engine's idle, improve starting, and perform at a much higher rpm. The housing is machined from billet 6061-T6 aluminum, using state-of-the-art CNC mills and lathes for a housing with no porosity or weak areas. For stability and endurance, an oversized steel shaft spins in a top-mounted sealed ball bearing, while an extra-long sintered bushing guides the shaft at the base of the housing. This shaft also receives a QPQ coating for low friction wear and resistance against corrosion from humidity and ozone buildup. They feature MSD's adjustable mechanical advance, which allows you to custom-tailor an ignition curve to match your engine's needs. Most models are also available with a vacuum advance canister to help improve economy.
These Pro-Billet Ready-to-Run EFI distributors from MSD are the perfect upgrade when you start making serious power with your EFI Ford or Chevy. They use a stock-style trigger pickup and come with plug-in connectors. Installation is simple by removing the stock distributor, then plugging in and bolting the new one in place! A maintenance-free magnetic pickup accurately triggers this ignition with increased output from the amplifier, easily outperforming stock ignitions. They will smooth out the engine's idle, improve starting, and perform at a much higher rpm. Their housings are machined from billet aluminum, using state-of-the-art CNC mills and lathes. For stability and endurance, an oversized steel shaft spins in a top-mounted sealed ball bearing for accuracy through the entire rpm range. Chevy models also feature an extra-long sintered bushing at the bottom and an extra oil tract machined into the bottom of the housing for improved lubrication. The tract delivers oil directly to the cam and distributor gears. All of the shafts receive a QPQ coating for low friction wear, and resistance against corrosion from humidity and ozone buildup. To finish things off, these distributors are 50-state legal as OEM replacements. The Chevrolet models have also been tested by the Underwriter's Laboratory, and are certified to meet or exceed safety standards for marine ignition systems as set by the U.S. Coast Guard
