MSD Distributor Cap and Rotor Kit P/N:8442

Keep spark jumping cleanly to every cylinder with the MSD Distributor Cap and Rotor Kit 8442, a direct-replacement cap-and-rotor set for MSD and GM V8 distributors. It uses a GM points-style socket cap, and MSD supplies these kits because the cap and rotor of any ignition system are wear items that should be considered routine maintenance. It's a fit for a wide range of classic GM cars and trucks, including the 1955-1975 Chevrolet Bel Air, 1967-1975 Chevrolet Camaro, 1964-1975 Chevrolet Chevelle, 1955-1975 Chevrolet Corvette, 1959-1975 Chevrolet Impala, 1969-1975 Chevrolet Nova, 1967-1974 GMC C15/C1500 Pickup, and the 1971-1972 Pontiac Ventura — see the Buyer's Guide tab for the full list of 61 applications.

• GM points-style socket cap: replaces the original cap on MSD/GM V8 distributors.
• Complete cap-and-rotor kit: renews two ignition wear items in one package.
• Maintenance-ready: MSD offers these replacement kits to make routine cap and rotor service easy.
• Applications: fits MSD/GM V8 distributors on the listed vehicles.

The cap distributes voltage from the coil to each plug wire tower, while the rotor passes it from the center terminal to each cap terminal in turn. Worn, cracked, or carbon-tracked caps and rotors are common signs these parts may need replacing.
