Ignition Contact Set Guide for 1955-1964 Studebaker Taxi
Keep your Studebaker's ignition firing reliably with the right contact set.
- The ignition contact set (points) is a normal wear item that requires periodic replacement, typically every 12,000-20,000 miles.
- Symptoms of failure include rough running, hard starting, stalling, and reduced power.
- Always replace the condenser along with the points to prevent premature failure.
- New aftermarket sets from a brand like Standard Ignition are a reliable and cost-effective choice compared to rare and expensive New Old Stock (NOS) parts.
Understanding the Ignition Contact Set in Your Studebaker
For a 1955-1964 Studebaker Taxi, the ignition contact set, or points, is a fundamental part of the ignition system. Unlike modern electronic ignitions, this system relies on a mechanical switch to time the spark. These points are a normal wear item, meaning they require periodic inspection and replacement to keep your engine running at its best. The rubbing block that rides on the distributor cam wears down, and the electrical contacts can become pitted or burned over time.
Symptoms of Failing Ignition Points
When your ignition points start to fail, the engine's performance will suffer. The signs are often gradual but will worsen over time. Look out for these common symptoms:
- No-Start or Hard Starting: Worn or misaligned points can't create the clean circuit break needed for a strong spark, making the engine difficult or impossible to start.
- Engine Misfires and Rough Idle: Pitted or dirty contact surfaces lead to an inconsistent spark, causing the engine to run unevenly, shake, or feel 'lumpy' at idle.
- Stalling: The engine may stall, especially at low RPMs or when coming to a stop, because the weak spark can't keep it running consistently.
- Reduced Power and Poor Acceleration: If the spark is weak or timed incorrectly due to worn points, your engine won't burn fuel efficiently, resulting in sluggish performance and hesitation when you press the gas pedal.
No Recalls or Technical Service Bulletins Found
A thorough search of the National Highway Traffic Safety Administration (NHTSA) database and other public records found no official recalls or technical service bulletins (TSBs) for ignition contact sets on 1955-1964 Studebaker models. This is normal for vehicles of this era, as the modern recall system was not yet in place. Failures are typically due to normal wear and tear.
Choosing the Right Aftermarket Part
Since Studebaker ceased production in the 1960s, 'new original' parts are not available. Your options are New Old Stock (NOS) or new aftermarket parts.
- New Old Stock (NOS): These are original parts that were never installed and have been in storage. While authentic, they can be very expensive and difficult to find. Additionally, related components like condensers can degrade over decades, even when unused.
- New Aftermarket: Modern aftermarket parts are the most practical and common choice. A reputable brand like Standard Ignition (a brand of Standard Motor Products) offers a reliable and affordable option. SMP has been a major manufacturer for American vehicles for decades and is a trusted name in the classic car community for ignition components. While some purists seek out older production parts, a new Standard set is a dependable choice for a daily driver or regular-use vehicle.
Pro Tip: When replacing your ignition points, it is highly recommended to also replace the condenser. A failing condenser is a primary cause of premature point burning and failure. Also, apply a small amount of distributor cam lubricant to the rubbing block on the new points to ensure a long service life.

Frequently Asked Questions
How often should I replace my ignition points?
For a vehicle that is driven regularly, a general rule of thumb is to inspect your points every year and expect to replace them every 12,000 to 20,000 miles. However, if you notice any of the failure symptoms, you should inspect them immediately.
Is replacing the ignition contact set a DIY job?
Yes, for someone with basic mechanical skills and tools, this is a very feasible DIY job. It involves removing the distributor cap and rotor, replacing the points and condenser, and setting the point gap with a feeler gauge. The difficulty is low, and it typically takes less than an hour.
What is 'setting the gap' and why is it important?
Setting the gap refers to adjusting the small space between the contact points when they are fully open. This gap is critical for proper ignition timing and 'dwell' (the amount of time the points remain closed). An incorrect gap will lead to poor engine performance. The correct specification for your Studebaker's distributor should be followed closely.
My Studebaker has a Delco distributor. Is it different?
Studebakers of this era could be equipped with either Prestolite or Delco-Remy distributors. The replacement procedure is similar for both. Some Delco models feature a small 'window' in the cap that allows you to adjust the dwell (point gap) with the engine running, which is a convenient feature. The parts themselves are specific to the distributor model, so ensure you order the correct set.
Technical Specifications
Varies by distributor model (Delco or Prestolite). Key specifications are the point gap and dwell angle. For example, a Champion engine's point gap is specified at .020 inches. Always refer to a shop manual for your specific engine and distributor combination.
