Ignition Contact Set Replacement for the 1949 Studebaker 2R17A Truck
Keep your classic Studebaker's engine firing reliably with the right ignition points.
- The ignition contact set (points) is a normal wear item on your 1949 Studebaker 2R17A that requires periodic replacement.
- Symptoms of failure include a no-start condition, hard starting, rough running, and stalling.
- Standard Ignition (Standard Motor Products) is the primary aftermarket brand for this part.
- Always replace the ignition condenser at the same time as the points to prevent premature failure.
Understanding the Ignition System in Your 2R17A
Your 1949 Studebaker 2R17A uses a simple and durable mechanical ignition system, with the ignition contact set at its heart. Unlike modern cars, your truck relies on these points to time the spark. Because the points have a small rubbing block that rides on the distributor cam, they are a normal wear item and were part of a regular tune-up back in the day. Over time, the contacts can pit and burn, and the rubbing block wears down, which changes the ignition timing and leads to poor engine performance.
Symptoms of a Failing Ignition Contact Set
When your ignition points start to fail, the signs are usually very clear because they directly affect the engine's spark. Watch for these common symptoms:
- Engine Will Not Start: This is the most severe symptom. If the points are completely burned out, pitted, or misaligned, they can't trigger the coil to create a spark. The engine will crank over but will not fire.
- Hard Starting: You may find the engine turns over for a long time before it finally starts. This can be caused by dirty or worn contacts that create a weak spark.
- Rough Running and Misfires: An engine that sputters, runs unevenly, or misfires is a classic sign of bad points. Worn or incorrectly gapped points cause an inconsistent spark, leading to a rough idle and hesitation when you accelerate.
- Engine Stalling: The engine may stall at a stoplight or even while driving. This can happen if the points are making poor contact, especially as engine components heat up.
Choosing the Right Aftermarket Part
Original Studebaker-branded ignition parts are no longer made, but high-quality aftermarket replacements are readily available. For a part like this, brand reputation and build quality are key.
Aftermarket Brand Assessment
| Brand | Quality Tier | Our Assessment |
|---|---|---|
| Standard Ignition (Standard Motor Products) | Trusted Aftermarket | Standard is a well-established American company that is the primary manufacturer of ignition components for classic vehicles like your Studebaker. Their parts are designed to meet or exceed original specifications and are a reliable choice. The "Blue Streak" line is considered their premium quality offering. |
OEM vs. Aftermarket Quality
For the 1949 2R17A, new original equipment (OEM) parts are not available. Your choice is between New Old Stock (NOS) parts and modern aftermarket parts. While NOS points might have high-quality contacts, the accompanying condensers can go bad from age, even when new in the box. For a critical wear item, a new, quality aftermarket set from a brand like Standard Ignition is a dependable and recommended option.
Estimated Replacement Costs

Pro Tip: Check for Distributor Shaft Wear
Before you install new points, grab the distributor shaft and try to move it from side to side. If there is noticeable wobble, the bushing inside the distributor is worn out. This can cause symptoms identical to bad points because the changing gap affects timing. If the shaft is loose, the distributor will need to be rebuilt for the new points to work correctly.
Frequently Asked Questions (FAQ)
Is replacing the ignition contact set a DIY job?
Yes, this is a very common and straightforward job for a classic vehicle owner. It requires basic hand tools, a screwdriver, and a feeler gauge. The entire process usually takes less than an hour.
Do I need to replace the condenser at the same time?
Yes, it is critical to replace the condenser whenever you replace the points. The condenser prevents the points from arcing and burning out. A bad condenser will destroy a new set of points very quickly.
What is "setting the gap" and why is it important?
Setting the gap is the most important step. It refers to adjusting the small space between the contacts when they are fully open. This is done with a feeler gauge. For many Studebaker 6-cylinder engines, a common gap is .020 inches. This gap controls your engine's ignition timing, and an incorrect setting will cause poor performance.
Should I convert to an electronic ignition?
This is a popular upgrade for classic cars. Electronic ignition kits replace the points and condenser, eliminating the need for regular adjustments. However, a stock points system that is properly maintained is very reliable and easy to fix on the side of the road with simple tools. The choice depends on whether you prefer modern convenience or original functionality.
