Detailed Description

DR-319 is a replacement distributor rotor used in the ignition system to transfer spark from the distributor cap to the correct terminal as the engine runs. This part number covers many classic GM platforms, including Chevrolet Chevette, Camaro, Nova, El Camino, and Pontiac Firebird, along with light-duty truck and van applications such as Chevrolet C10, K10, G10, and GMC G15. If you are servicing a 1975-1977 Chevrolet C10 or a 1976-1987 Pontiac Acadian, DR-319 provides the correct rotor listing for those applications.

This part cross-references with Standard Ignition DR-319 for the same application.

What It Helps Address

• Engine misfire caused by worn rotor contact surfaces
• Hard starting related to weak or inconsistent spark routing
• Rough idle from ignition timing transfer issues inside the distributor
• Intermittent spark delivery in older GM distributor systems
• Service replacement needs on Chevrolet, GMC, Pontiac, and Oldsmobile ignition systems

Installation Notes and Tips

Verify distributor style and rotor fitment before installation, especially on applications with notes such as the 1976 GMC Jimmy with push-on rotor. Inspect the distributor cap, shaft, and ignition components at the same time so the new rotor is installed into a clean, serviceable ignition assembly. Confirm the vehicle application against the listed year, make, and model before ordering.

Standard Ignition DR-319 is cataloged as Blue Streak Premium Quality for the listed applications and is backed by Standard Ignition’s product coverage for the specified fitments.
