The RAM 1500 uses lug nuts with M14x1.5 threads, a 60-degree conical seat, and a 22mm socket size for installation and removal.


Overview of stock lug nut specifications


The RAM 1500’s factory lug nuts are designed to fit the vehicle’s 5x139.7 mm bolt pattern and standard wheels. The key details you’ll need for replacement or maintenance are the thread size, seat type, and the correct socket size to use with your wrench or impact gun.


Before diving into the specifics, here is a concise rundown of the essential factory specs you’re likely to encounter when servicing RAM 1500 wheels.

When replacing lug nuts or wheels, sticking to the OEM specifications helps ensure proper seating, torque, and clearance with the wheels and brake components.


Why some variations appear


While these specifications cover most RAM 1500 models from recent years, variations can occur with special editions, regional specifications, or aftermarket wheels. Some aftermarket setups may use different seat types, thread sizes, or socket requirements. Always verify the exact specs for your vehicle by checking the owner’s manual, the OEM parts catalog, or the packaging of the lug nuts and wheels you plan to use.


How to verify for your specific vehicle


To confirm the lug nut size for your exact RAM 1500, you can:



  • Consult the owner's manual or RAM’s official parts catalog for your VIN.

  • Consult the wheel manufacturer’s documentation if you’re using aftermarket rims.


If you’re unsure, bring a sample lug nut to a reputable parts store or mechanic to ensure you get the correct replacement.
