Chevy D.U.I. Distributors
The Chevy D.U.I. Distributor was the first, and still is the best performance H.E.I. Distributor. Inferior copy cats have come and gone, but the D.U.I. remains the most popular choice for hot rodders around the globe. A super smooth advance curve is machine calibrated, providing you with instant throttle response, while eliminating engine damaging detonation. The 50,000 Volt D.U.I. Coil teams up with our high dwell Dyna-Module, allowing you to run a massive .055” plug gap. 8, 6, & 4 cyl. applications are available.
