Distributor Cap Guide for the 1960 Studebaker 5E12
Get your classic V8 running smoothly with the right distributor cap.
- The 1960 Studebaker 5E12 uses a 9-post distributor cap for its 259 V8 engine.
- Symptoms of failure include misfires, hard starting, and rough idle; visual inspection for cracks or corrosion is the best diagnostic.
- Quality aftermarket brands like Standard Ignition or Walker Products are the correct and only 'new' options available.
- Always replace the distributor rotor at the same time as the cap for a complete tune-up.
Signs of a Failing Distributor Cap on Your Studebaker
A distributor cap is a maintenance item that wears out from heat, vibration, and constant high voltage. When it starts to fail, the spark can become weak or inconsistent. Watch for these common symptoms in your truck:
- Engine Misfires: The truck may stumble, hesitate, or shudder when you accelerate. This is a classic sign that spark isn't reaching one or more cylinders correctly.
- Hard Starting: The engine cranks for a long time before it starts, or it might not start at all. This problem can be worse in damp weather, as moisture can get into tiny cracks in an old cap.
- Rough Idle: When stopped, the engine may shake or run unevenly. This can be caused by worn or corroded metal contacts inside the cap.
- Stalling: In severe cases, a badly cracked or corroded cap can cause the engine to stall unexpectedly.
Visual Inspection is Key
The best way to diagnose a bad distributor cap is to look at it. Remove the two clips holding it down and inspect the inside and outside. Look for cracks, moisture, white carbon tracks between the terminals, or any corrosion or pitting on the metal contacts. If you see any of these signs, it's time for a replacement.
Choosing the Right Aftermarket Cap
Original Studebaker parts are no longer in production, so any new distributor cap you purchase will be an aftermarket part. For a classic truck like the 5E12, aftermarket quality for ignition parts is generally reliable and is the standard choice for repairs and tune-ups. The 1960 5E12 uses the Studebaker 259 V8 engine, which requires a cap with 9 posts (one for the coil, eight for the cylinders).
Aftermarket Brand Tiers
For your Studebaker, brands like Standard Ignition and Walker Products are readily available. Here’s an honest breakdown:
- Standard Replacement (Good): Brands like Walker Products offer reliable, OE-quality replacement parts that are cost-effective. They are designed to meet the original specifications and are a solid choice for regular driving and maintenance.
- Premium Replacement (Better): Standard Ignition (SMP) is often considered a premium brand in the classic car community. Their caps may feature higher-quality materials like high-dielectric polyester and solid brass terminals, which resist corrosion and carbon tracking better than standard components. This is a great option for owners who want extra durability and peace of mind.
Always Inspect New Parts
Some classic car owners have noted that quality control on parts from all manufacturers can vary. Before installing any new cap, take a moment to inspect it. Look inside for any plastic shavings or debris from the manufacturing process. Ensure the metal contacts are smooth and properly formed. Returning a questionable part before installation is much easier than diagnosing a problem later.

Frequently Asked Questions (FAQ)
Should I replace the distributor rotor with the cap?
Yes, absolutely. The rotor is the part that spins inside the cap, and its tip wears down just like the cap's terminals. Since you already have the cap off, replacing the inexpensive rotor at the same time is critical for a complete and reliable ignition tune-up.
Can I replace the distributor cap myself?
Yes, this is a perfect job for a beginner. The cap is held on by two clips and is indexed to only fit one way. The most important step is to transfer the spark plug wires from the old cap to the new one, one at a time, to ensure the firing order remains correct. The entire job usually takes less than 30 minutes.
Are there any recalls for the 1960 Studebaker 5E12 distributor cap?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or factory defects for the ignition system on this vehicle. Any problems you encounter are due to the age and normal wear of the part.
What is the most common mistake when ordering this part?
For Studebakers, the most common error is ordering a cap for the wrong engine. The 5E12 uses a V8, which needs a 9-post cap. Ordering a 7-post cap for a 6-cylinder engine by mistake will not work. Always confirm you are buying the cap for the Studebaker V8.
