Route high-voltage spark from the coil to each plug wire with the Standard Ignition Distributor Cap DR-439. It installs as a direct-fit replacement for the listed applications, including the 1962-1966 Buick Special, 1964-1966 Buick Skylark, 1964 Buick Sportwagon, 1964-1965 Oldsmobile F85, plus numerous Jeep models such as the CJ5, CJ6, DJ5, FC150, FC170, Commando, and Universal — see the Buyer's Guide tab for the full vehicle list and exact years.
- Glass/mineral reinforced polyester resin: high dielectric strength for less carbon tracking and greater resistance to electrical breakdown.
- RFI resistors where specified: on applications that call for them, they help suppress radio static and voltage spikes.
- Solid brass terminals where available: where fitted, they make solid connections with greater resistance to electrical pitting and corrosion.
- OE ignition build: from a global manufacturer of original-equipment ignition products, with quality control maintained through the manufacturing process.
The cap covers the distributor and carries the spark from the rotor out to each cylinder's plug wire. If a cracked, carbon-tracked, or corroded cap is the cause of misfires, rough idle, or hard starting, this replaces it. Diagnose the underlying cause before replacing.
