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 chro-moly 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 steel shaft that spins the advance and reluctor receives a friction reducing coating plus is guided by a sealed ball bearing and long sintered bushing. This combination provides stable timing signals and spark delivery at any rpm. Reluctoring chores are handled by MSD's race proven, maintenance-free magnetic pick-up.;
