What size socket is a Ram Lug Nut?
For most Ram pickups (Ram 1500, 2500, 3500) with stock wheels, the lug nuts typically use a 13/16-inch hex socket. However, sizes can vary by model year, wheel type, and aftermarket hardware, so you should verify the exact size on your vehicle. As of 2024–25, 13/16-inch is the common default, but exceptions exist.
How Ram lug nuts vary by model and wheel
Ram's lineup includes multiple wheel patterns and lug-nut designs across models and wheel options, so there isn’t a single universal size. The socket size you need depends on the hex across flats of the lug nut and can range from the common 13/16-inch to larger or metric sizes in some setups.
Common sizes you may encounter include the following. Start with the most common size and adjust if it doesn’t engage properly:
- 13/16-inch (20 mm) hex: The most frequently encountered size on many Ram 1500s and many 2500/3500 setups with stock wheels.
- 3/4-inch (19 mm) or 7/8-inch (22 mm) hex: Occasionally seen on certain heavy-duty or aftermarket wheel configurations.
- 21 mm or 22 mm metric hex: Some aftermarket lug nuts and wheels use metric sizing.
To avoid damage, never force a socket onto a lug nut. If a socket doesn’t fit, try the next size, and verify with sources such as the owner's manual, wheel specification, or the wheel manufacturer.
How to confirm the exact size for your Ram
Because exact sizes vary by year, trim, and aftermarket parts, follow these steps to confirm the correct lug-nut socket size for your Ram:
- Inspect the lug nut head for any size markings. Some nuts are stamped with the hex size.
- Measure across flats: Use a caliper or a ruler to measure the distance between opposite flat surfaces on the lug nut to determine the hex size.
- Check official documentation: Refer to your owner's manual or the wheel manufacturer’s specifications for lug-nut size and thread pitch.
- Ask a professional: If in doubt, a dealership or tire shop can confirm the correct size for your specific vehicle configuration.
Once you identify the correct socket, ensure you use a torque wrench and follow the recommended torque specs for your Ram to maintain safety and wheel integrity.
Additional considerations
Some newer Ram models with heavy-duty wheels or aftermarket rims may use different lug-nut hardware, including different seat shapes or thread sizes. If you replace lug nuts or wheels, verify compatibility with your hubs and studs to avoid misfit or stripping.
Summary
The standard socket size for Ram lug nuts is commonly 13/16-inch, but there are exceptions based on model year, trim, wheel options, and aftermarket components. To ensure accuracy, check the lug nut itself, refer to official documentation, or consult a dealership or tire shop. Always use the correct socket size and torque specification when installing or removing lug nuts.
