1955-1956 Studebaker E15 Ignition Contact Set Guide
Keep your classic Studebaker truck running strong with the right set of ignition points.
- The ignition contact set (points) is a critical wear item that requires periodic replacement and adjustment.
- Always replace the condenser when you replace the points to protect the new set from premature failure.
- Setting the correct point gap with a feeler gauge is essential for proper engine performance.
- Before replacing, check for a worn distributor bushing, which can cause similar symptoms.
Symptoms of a Failing Ignition Contact Set
When the ignition points in your Studebaker E15 start to wear out, they can cause several noticeable problems. The contacts can become pitted or burned from the electrical arc that occurs when they open, and the small rubbing block that rides on the distributor cam can wear down. This wear changes the gap and timing, leading to poor engine performance.
- Engine Misfires: The engine may sputter or hesitate, especially when accelerating or under load, like climbing a hill.
- Rough Idle: The truck may idle unevenly or stall when stopped.
- Difficulty Starting: A worn or improperly gapped set of points can make it hard to start the engine, or prevent it from starting at all.
- Loss of Power: You might feel that your truck is less powerful than usual because the spark timing is incorrect.
Choosing the Right Aftermarket Ignition Points
For a vintage vehicle like the 1955-1956 Studebaker E15, finding original factory parts is nearly impossible. Aftermarket parts are the standard for these trucks. The good news is that ignition points are a simple, proven technology, and reputable aftermarket brands produce reliable sets.
Standard Ignition is a well-known brand that has been making quality ignition components for decades. For your Studebaker, their products are a dependable choice. The key is not necessarily the brand, but ensuring the points are installed and adjusted correctly.
Pro Tip: Check the Distributor Shaft
Before installing new points, check the distributor shaft for side-to-side play. A worn bushing in the distributor can cause the point gap to change as the engine runs, leading to a persistent misfire even with new parts. If there's significant wobble, the distributor may need to be rebuilt or replaced.

Frequently Asked Questions (FAQ)
Should I replace the condenser at the same time?
Yes, it is highly recommended. The condenser is a capacitor that absorbs the electrical surge when the points open, preventing them from arcing and burning out prematurely. Many owners of classic cars report that new condensers can sometimes be faulty, so it's wise to buy a quality one and even keep the old one as a spare if it was working.
What tools do I need to replace the ignition points?
You will need basic hand tools like a screwdriver and wrenches to remove the distributor cap. The most important special tool is a feeler gauge. This is used to set the correct gap between the point contacts when they are fully open. An incorrect gap is a common cause of poor performance.
What is the correct point gap for my Studebaker E15?
While specific E15 specs are scarce, Studebaker V8 engines of this era typically require a point gap between .016" and .020". Always check a service manual for your specific engine if possible. Setting the correct dwell angle with a dwell meter is the most accurate method, but a feeler gauge will get you very close.
Is an electronic ignition conversion a better option?
Many owners choose to convert to an electronic ignition system. These systems replace the points and condenser with a solid-state module, eliminating the need for regular adjustment. While they can offer improved reliability and a more consistent spark, a properly maintained points-based system is simple, cheap, and very effective for a classic truck that isn't driven daily.
