Distributor Rotor for Classic GM and Chrysler Applications

Standard Ignition DR-142 is a distributor rotor built for older ignition systems that need stable spark transfer and dependable fitment. It is listed for select Pontiac Catalina, Buick Roadmaster, Oldsmobile 88, Oldsmobile 98, Cadillac Commercial Chassis, and Chrysler Imperial applications.

Key Features

  • High-dielectric alkyd material helps resist dirt buildup and reduces carbon tracking
  • Solid brass segments improve conductivity for stronger voltage transfer to the spark plugs
  • Shaft retention clips are used where required for secure fit and proper rotor location
  • Built for distributor and magneto ignition systems in classic vehicles
  • Standard Ignition DR-142 is engineered for consistent rotor performance in vintage applications

Detailed Description

This distributor rotor is designed to transfer ignition voltage through the distributor cap with minimal loss, helping maintain reliable spark delivery in older engines. The brass segment design supports better electrical conductivity, while the alkyd construction helps limit contamination that can contribute to carbon tracking. Standard Ignition DR-142 is a direct-fit replacement for select 1937-1938 Chrysler Imperial, 1946-1949 Cadillac Commercial Chassis, 1950 Oldsmobile 88 and 98, 1950-1952 Buick Roadmaster, and 1950-1954 Pontiac Catalina applications. This part cross-references FEL-PRO 1487 for the same application.

What It Helps Address

  • Weak or inconsistent spark transfer through the distributor
  • Carbon tracking inside the distributor cap
  • Misfire concerns caused by worn rotor contacts
  • Electrical resistance from deteriorated rotor materials
  • Fitment issues on original-style ignition service work

Installation Notes and Tips

Verify distributor cap style and rotor indexing before installation. Inspect the cap, terminals, and shaft for wear or contamination, since a new rotor performs best with clean mating components. Confirm the application by year, make, and model before service; Standard Ignition DR-142 is listed for 1950-1954 Pontiac Catalina, 1950-1952 Buick Roadmaster, 1950 Oldsmobile 88, 1950 Oldsmobile 98, 1946-1949 Cadillac Commercial Chassis, and 1937-1938 Chrysler Imperial.

Quality Assurance

Standard Ignition uses materials and construction methods developed from long-term ignition system research and development. The rotor is built to deliver dependable conductivity and service life in classic distributor applications.
