Lug Nuts Needed for This Wheel

Thread Pitch: 9/16"-18 | Lug Pattern: 8-Lug | Quantity: 8 per wheel (32 for a set of 4)

This is an aftermarket wheel, so it needs aftermarket-style lug nuts rather than factory OE lug nuts. Browse the full OBS Lug Nuts collection to find the right style and finish.

Running a dual-rear-wheel 3500 dually instead? See our OBS 8 Lug Dually Wheels collection for dually-specific offset and backspacing. Not sure this is your bolt pattern? Browse OBS Wheels to shop by your truck's actual fitment, and check our OBS C2500/C3500 Lowering Kits collection if you're planning a drop.
