APM Advance Assembly
This Comp Master brand advance assembly from American Prime has a 304 stainless steel base, center post and pivot pins.
The weights are coated with a specially formulated polymer that protects from heat saturation, reduces friction, and, in most cases, strengthens the component to make it more efficient. The special CNC-coiled springs hold precision tolerances controlling spring rates to within 5% of specification to provide the maximum advance and retard applicable to the model.
They are manufactured with precision-drawn wire, then zinc plated for corrosion protection with post baking for relieving any potential of hydrogen embrittlement. The kit includes the center bolt, is made in the U.S.A. and assembled at the APM facility in Santa Fe Springs, California. Rebuild and spring replacement kits are also available.
