A Guide to the Ignition Contact Set for 1949-1953 Studebaker 2R5 Trucks
Keep your classic Studebaker's engine firing on all cylinders by understanding its ignition points.
- The ignition contact set (points) is a normal wear-and-tear part that requires periodic replacement on your Studebaker 2R5.
- Symptoms of failure include engine misfires, hard starting, or a complete no-start condition.
- The correct point gap for the Champion engine is .020 inches, and setting it accurately with a feeler gauge is crucial for proper performance.
- Quality aftermarket brands like Standard Ignition are a reliable and common choice for these classic trucks, as new OEM parts are unavailable.
Signs of a Failing Ignition Contact Set
Ignition points are a wear item, meaning they need to be replaced as part of regular maintenance. The constant opening and closing, along with the electrical arc, causes the contact surfaces to pit and burn over time. When your 2R5's ignition points start to fail, you'll notice some clear symptoms:
- Engine Misfires: Worn or dirty points can cause an inconsistent spark, leading to the engine running rough or stumbling.
- Hard Starting: If the points are not making good contact or the gap is incorrect, the engine may be difficult to start.
- Engine Will Not Start: If the points are completely burned out or the rubbing block that opens them is worn down, they will not trigger the coil to create a spark, and the engine will not start at all.
- Poor High-Speed Performance: A weak breaker arm spring or incorrect point gap can cause the points to "chatter" or "float" at higher RPMs, leading to a loss of power.
A Note on Condensers
The ignition condenser is a small capacitor that works with the points. Its job is to prevent a large arc from forming when the points open, which protects them from burning out too quickly. It is highly recommended to replace the condenser every time you replace the ignition contact set. Many tune-up kits include both parts.
Choosing the Right Aftermarket Ignition Points
For a classic truck like the 1949-1953 Studebaker 2R5, new original equipment manufacturer (OEM) parts are no longer produced. The good news is that the aftermarket has long supported these vehicles. High-quality aftermarket parts are the standard for keeping these trucks on the road.
Standard Ignition (Standard Motor Products):
Standard Ignition is a well-known and long-standing brand in the aftermarket industry. They produce ignition components that are designed to meet or exceed original specifications. For vehicles like the Studebaker 2R5, brands like Standard Ignition are a reliable and trusted choice for owners and mechanics. Their T-Series points are specifically noted for their quality and reliability.

Pro Tip: Setting the Point Gap
The most critical step of installation is setting the correct gap when the points are fully open. For Studebaker Champion engines of this era, the point gap should be set to .020 inches. Use a feeler gauge to ensure accuracy. An incorrect gap will lead to poor engine performance and premature part failure.
Frequently Asked Questions (FAQ)
How often should I replace the ignition points on my Studebaker 2R5?
Ignition points are a regular maintenance item. While there's no strict interval, it's good practice to inspect them during every major tune-up or at least once a year. If you notice rough running or hard starting, the points are one of the first things to check. Some owners who drive their classic vehicles regularly may replace them every 10,000-12,000 miles as preventative maintenance.
Is replacing ignition points a difficult job?
No, for a mechanically inclined owner, this is a very straightforward job. It requires basic hand tools, a feeler gauge, and access to the distributor. The entire process usually takes less than an hour. It involves removing the distributor cap and rotor, unscrewing the old points and condenser, installing the new ones, and setting the correct gap.
Should I consider converting to electronic ignition?
Many owners of classic vehicles choose to convert from a points-based system to an electronic ignition. Electronic systems offer the benefit of being maintenance-free and can provide a more consistent spark. However, a properly maintained points system is extremely reliable and easy to troubleshoot and fix on the side of the road with simple tools. For a stock 2R5, a quality set of points will perform perfectly well. The choice often comes down to personal preference for originality versus modern convenience.
What is the correct point gap for my Studebaker 2R5?
The correct distributor point gap for the Studebaker Champion engine used in the 2R5 is .020 inches. This measurement is taken when the rubbing block on the points is on the highest point of a lobe on the distributor cam.
