For Ford enthusiasts that are serious about performance! Just under the brass terminals of the MSD cap and rotor is an easy-to-adjust mechanical advance assembly. The assembly is fine blanked from Chromoly Steel, TIG-welded for strength plus receives a QPQ coating. The precision weights glide on nylon bushings for smooth advancement and different springs and stop bushings are supplied so a variety of advance curves can be tuned. The adjustable mechanical advance assembly allows you to accurately and easily modify the advance curve to match your specific application. The steel shaft that spins the advance and reluctor receives a friction-reducing coating and is guided by a sealed ball bearing and long sintered bushing. This combination provides stable timing signals and spark delivery at any rpm. Triggering chores are handled by MSD's race-proven, maintenance-free magnetic pick-up. MSD premium distributors come complete with a race rotor and alkyd cap. The 85827 Distributor comes with Bronze Gear 8583 already installed and is designed for camshafts requiring a bronze distributor gear: - Made of a bronze/aluminum/nickel alloy (AMPCO 45) - Softer material will not damage the camshaft - Used with billet steel cams - Should be changed more frequently than other gear materials Must be used with MSD ignition.
