Standard Ignition JR-166 Distributor Rotor

Distributor Rotor for Chrysler and Dodge

The Standard Ignition JR-166 distributor rotor is built for direct replacement service on select Chrysler and Dodge applications. It uses a high-dielectric alkyd body to help resist dirt buildup and reduce carbon tracking, while solid brass segments support strong conductivity and consistent spark delivery to the plugs.

• Distributor rotor for ignition distributor service
• High-dielectric alkyd construction helps resist dirt adhesion
• Solid brass segments support better conductivity
• Designed to promote higher voltage spark transfer
• Shaft retention clips used where required for fit and performance
• Compatible With 1995-1997 Chrysler Cirrus, N/A, rotor marked T231
• Compatible With 1996-1997 Chrysler Sebring, N/A, rotor marked T231
• Compatible With 1995-1997 Dodge Avenger, N/A, rotor marked T231
• Compatible With 1995-1997 Dodge Stratus, N/A, rotor marked T231
• Compatible With 1995 Chrysler Sebring, N/A, ID No. T231

Fitment and Application Details

Standard Ignition JR-166 is a distributor rotor for vehicles using the T231 distributor identification or rotor marking shown in the fitment data. It cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. This part is used in ignition distributor systems on Chrysler Cirrus, Chrysler Sebring, Dodge Avenger, and Dodge Stratus models from the listed years, including 1995-1997 Chrysler Cirrus and 1995-1997 Dodge Stratus.

What This Part Helps Address

• Weak or inconsistent spark transfer through the distributor
• Carbon tracking caused by contamination on the rotor surface
• Misfire conditions related to worn rotor contacts
• Ignition performance loss from deteriorated rotor conductivity
• Fitment issues on T231-marked distributor applications

Installation Notes

Verify the distributor marking before installation and match the rotor to the T231 identification noted in the fitment data. Inspect the distributor cap, rotor contact surfaces, and related ignition components for wear or contamination during service. Confirm proper seating of the rotor and any required shaft retention clip engagement where applicable.

Quality Assurance

Standard Ignition designs this rotor with materials and construction aimed at stable electrical performance and extended service life in distributor ignition systems. The JR-166 reflects the brand's long-running focus on ignition component engineering and application-specific fitment.
