Speedmaster K1045 steel enclosed elastic dampers are tested to 12,500 RPM for explosion proof racing application. The "S" shape gap between inner and outer ring is press inserted with sulfated elastic rubber to ensure the damper will not disintegrate under any circumstance. All dampers are tested to withstand 15 tons press force without separation or deterioration. This damper is externally balanced; the term external balanced damper refers the built in weight or offset in the casting. When identifying your existing damper, (balancer) you must look on the backside. This is not visible if the damper is mounted on the engine. If your damper has no offset in the casting or weight, then you have an internal, (neutral) style damper. If you do see the offset in the casting or a weight, you have what is classified as an external damper.
