On the 2018 Ram 1500, there isn’t one universal torque value. The most commonly referenced number is the wheel lug nut torque, typically 140 ft-lbs (190 Nm) for five-lug wheels. The exact torque for other fasteners depends on the component, engine, and transmission, so consult the factory service manual for specifics.
Common torque spec you’re most likely to encounter
The wheel lug nut torque is what most vehicle owners will need during tire service and basic maintenance. It’s important to use the correct star or crisscross pattern and recheck after installing a wheel.
- Wheel lug nuts: 140 ft-lbs (190 Nm). Follow a star-pattern torque sequence and recheck after wheel installation and after driving 50–100 miles (80–160 km).
That covers the most frequently referenced spec for a 2018 Ram 1500. For other fasteners and components, exact values vary by engine and model, so refer to the official documentation for precision.
Where to find the exact torque specs for your 2018 Ram 1500
Because this model year offers multiple engines and configurations, many torque specs are component-specific. Use official, engine- and component-level documentation to verify numbers for your truck.
- Ram Factory Service Manual (FSM) for your engine and trim level.
- Mopar Repair Information Portal (official service information for current specs).
- Authorized dealer service departments or reputable repair guides (Chilton/Haynes) as supplementary references.
In practice, always check the source that matches your exact configuration (engine type, transmission, axle, and options) before tightening fasteners beyond generic guidance.
Practical torque guidelines and best practices
Torque pattern and verification
Always use a calibrated torque wrench, tighten fasteners in the correct sequence (for example, lug nuts in a star pattern), and re-torque after initial drive or specified break-in miles if the service manual calls for it. For aluminum components and critical joints, cleaner threads and per-spec lubricants can affect the final torque value, so follow the manual’s guidance.
- Use the proper torque wrench and set to the specified value.
- Apply the correct tightening sequence and torque in stages if required by the manual.
- Recheck torque after initial driving or per the service instructions.
These practices help prevent loosening, reduce the risk of damage, and ensure safety during operation.
Summary
The 2018 Ram 1500 does not have a single torque specification; the most common is wheel lug nut torque at 140 ft-lbs. For other fasteners, torque values vary by engine and component, so rely on the factory service manual or Mopar repair information portal for exact numbers. Always follow the proper tightening sequence and verify with a torque wrench.
