Quick Answer: Jeep JK lug nuts torque to roughly 100 ft-lbs (130 N·m). The 2007–2018 factory service manual lists an acceptable range of about 92–132 ft-lbs, so 100 ft-lbs is a safe practical target. Always use a torque wrench in a star pattern and re-torque after 50–100 miles.

This reference is educational and covers common 2007–2018 Jeep Wrangler JK configurations. Exact torque values, capacities, fluid requirements, fasteners and service sequences can vary with model year, engine, axle, factory options and prior repair. Verify the exact vehicle and use the applicable factory service information before tightening a fastener or filling a component. The 2018 JK Owner’s Manual and Mopar’s maintenance schedule are starting points for 2018 operating and maintenance information; use matching documentation for other model years.

Jeep JK Lug Nut Torque & Size
- Lug nut torque: ~100 ft-lbs (130 N·m). FSM range ~92–132 ft-lbs.
- Thread size: M14 x 1.5 (2007–2018 Wrangler JK).
- Spare-tire carrier nuts: much lower — about 40 ft-lbs. Over-tightening can crack the carrier.
- Note: 130 is the Newton-metre figure, not ft-lbs — do not torque to 130 ft-lbs.
How to Torque JK Lug Nuts
- Make sure threads are clean and dry (do not oil the studs).
- Hand-thread each nut, then snug them in a star/criss-cross pattern.
- Final-torque to ~100 ft-lbs in the same star pattern.
- Re-torque after 50–100 miles — especially after installing new wheels or wheel spacers.
Aftermarket wheels or spacers may specify a different value; follow the manufacturer’s figure when provided, and confirm against your FSM.
