Standard Ignition Distributor Cap P/N:DR-437
Help keep high-voltage spark reaching the right cylinder with the Standard Ignition Distributor Cap DR-428, a replacement cap that covers the distributor and carries coil voltage from the rotor to each spark plug wire terminal. It is listed for many models, among them the 1958-1962 Chevrolet Impala, 1960-1962 Chevrolet Suburban and 1959 GMC PM153. See the Buyer's Guide tab for the full list and engine details.

What does the Standard DR-428 distributor cap do?
It covers the distributor and routes high voltage from the rotor to the spark plug wire terminals, so each cylinder receives spark in firing order.
What is the DR-428 distributor cap made of?
Standard states it is made of high dielectric strength, glass/mineral reinforced polyester resin, designed for less carbon tracking and greater resistance to electrical breakdown.
What are signs a distributor cap may need replacing?
Misfires, hard starting, rough running, cracks, carbon tracks or corroded terminals. Worn wires or a worn rotor can cause similar symptoms, so diagnose the cause first.
Any tips for installing a new distributor cap?
Move the spark plug wires from the old cap to the new one one at a time so the firing order stays correct, and inspect the rotor while the cap is off.
