Send clean, high-voltage spark to the right cylinder every time with the ThunderSpark Distributor Rotor 926-1013. It drops in as a direct-fit replacement for the 1991-1995 Chevrolet Lumina APV, 1991-1994 Oldsmobile Silhouette, and 1991-1995 Pontiac Trans Sport — see the "Vehicles it fits" section for engine-level details. Mounted on the distributor shaft, the rotor transfers current from the ignition coil to the correct terminal on the distributor cap, keeping spark timing aligned for each engine cylinder.
- Accurate spark distribution: transfers high-voltage current from the coil to the correct cap terminal for proper timing across every cylinder.
- OE fit and function: engineered to meet OE fit, form, and function standards for correct alignment and spark delivery.
- Arc-resistant build: high-dielectric-strength materials resist arcing and heat degradation under demanding operating conditions.
- Corrosion-resistant contact: a corrosion-resistant contact surface supports consistent conductivity and output over time.
If a worn or arced rotor is the cause of hard starting, misfires, or hesitation, replacing it with the 926-1013 restores proper spark delivery. Always diagnose the ignition fault before replacing.

Frequently Asked Questions
What does the distributor rotor do?
It rides on the distributor shaft and transfers high-voltage current from the ignition coil to the correct terminal on the distributor cap, distributing spark to each engine cylinder in the proper firing order.
Which vehicles does the 926-1013 fit?
It's a direct-fit replacement for the 1991-1995 Chevrolet Lumina APV, 1991-1994 Oldsmobile Silhouette, and 1991-1995 Pontiac Trans Sport. Check the "Vehicles it fits" section to confirm your engine.
What are signs the rotor may need replacing?
Hard starting, misfires, or engine hesitation can be signs of a worn or arced rotor. Diagnose the ignition system first, since these symptoms can have other causes.
Is this rotor built to OE standards?
Yes. It's engineered to meet OE fit, form, and function standards, with high-dielectric-strength materials that resist arcing and heat degradation.
What interchange numbers does this rotor replace?
It cross-references 51-5569, RD-102, 6C1, 4R1055, D224, 3959, 01986109, 19110942, 1986109, 1212218, DR328, and DR931.
