Custom-Tuned Distributors for Maximum Power

Davis Unified Ignition (D.U.I.) Dodge Tri-Power Ignition Systems are designed for Dodge/Chrysler engines where standard D.U.I. distributors will not fit due to size. The Tri-Power ignition system is equipped with a Dyna-Module (HEI style) that is mounted externally to the distributor housing and also includes a high voltage Inferno coil. Each distributor features a super smooth advance curve to eliminate engine damaging detonation and provides quicker starting, smoother idle, and better performance up to 7,500 RPMs.
