What size are the lug nuts on a 2004 Dodge Ram?
Most 2004 Dodge Ram pickups use lug nuts sized 9/16-18.
There are variations depending on model (1500 vs heavy‑duty 2500/3500) and wheel type. The following sections explain typical configurations and how to verify the correct size for your truck.
Common lug nut configurations
Use these as typical guidelines, but confirm on your specific vehicle. Lug nut size can vary with wheel type and aftermarket parts.
- Ram 1500 (5-lug, 5x127 mm bolt pattern): lug nuts are typically 9/16-18 with a 60-degree conical seating.
- Ram 2500/3500 (8-lug, 8x165.1 mm bolt pattern): lug nuts are typically 9/16-18 with a 60-degree conical seating; some wheels may require a different seat type—verify if you have aftermarket or specialty wheels.
When replacing wheels or hardware, ensure the seat type and thread pitch match your wheel studs and lug nuts. Using the wrong size can damage threads or be unsafe.
How to verify the lug nut size on your 2004 Ram
Follow these steps to confirm the exact size for your vehicle, especially if you’ve upgraded wheels or are buying replacements.
- Check the owner's manual or the tire information label on the door jamb for recommended lug nut size and wheel specs.
- Inspect the lug nuts on your wheels: read any stamping on the nut itself or measure the thread diameter after removing one nut.
- Confirm the bolt pattern and seat type: 5x127 mm or 8x165 mm and a 60-degree conical seat are common, but aftermarket wheels may differ.
- When in doubt, bring a sample lug nut to a parts store or contact the dealer with your VIN to confirm exact requirements.
Getting this right is essential for safety and wheel integrity. If your wheels are aftermarket or you’re unsure, professional verification is advised.
Seat types and compatibility
60-degree conical (acorn) seat
The most common lug nut style for 2004 Ram stock wheels. It provides a wide seating surface and good alignment with most factory and aftermarket wheels designed for 60-degree conical seats.
Other seat styles and considerations
Some aftermarket wheels use different seat designs, such as mag or narrow/semi-conical seats. If your wheels specify a different seat, you’ll need lug nuts to match the seat type and thread size exactly to avoid improper seating and potential failure.
Summary
In short, for a 2004 Dodge Ram, lug nuts are typically 9/16-18 across the common 5- and 8-lug configurations, with a 60-degree conical seat being the norm. Always verify against your specific model, wheel type, and seat design, and consult the manual or a parts professional if you’re unsure. Matching bolt pattern, seat type, and thread pitch is essential for safety and proper wheel function.
