GM HEI Internal-Coil Cap and Rotor Kit (6-Cyl./V8 Options) by Davis Unified Ignition®

Brass cap terminals, an insulating cap body and a matching rotor service the selected HEI version.

This Davis Unified Ignition® kit supplies a replacement cap and rotor for the selected internal-coil HEI distributor. Brass terminals resist corrosion and conduct the ignition output, while the cap's insulating resin helps resist electrical burn-through. Nylon rotor screws avoid adding conductive metal fasteners in the rotor mounting area. The six-cylinder and V8 kits use different cap configurations; select the version that matches the installed distributor. The ignition coil and module are not part of the cap-and-rotor kit.

• Selected GM HEI/DUI internal-coil distributors (See full fitment list below) • Options: six-cylinder internal-coil or V8 internal-coil/L-clamp • Brass distributor-cap terminals • Insulating resin cap body and matching rotor • Nylon rotor mounting screws • Cap and rotor supplied; coil and module not included
