6x120 Bolt Pattern
A bolt pattern, or lug pattern, is a parameter that defines the number of lug holes in the wheel and the diameter of the circle (PCD, Pitch Circle Diameter) that the lug holes form. 6x120 bolt pattern, or 6x4.72 when converted to inches, indicates the wheel has 6 lug holes spaced evenly on a circle with a diameter of 120 millimeters or 4.72 inches. The 6x120 bolt pattern is common to Chevrolet, Buick, GMC, Saab and Cadillac models.
The 6x120 bolt pattern is a specific layout used in the wheel mounting mechanism of some vehicles, indicating that a wheel has six lug holes evenly spaced in a 120mm diameter circle. This bolt pattern is crucial for ensuring that the wheel is properly aligned and securely attached to the vehicle's hub. Primarily found in certain models of SUVs, trucks, and larger vehicles, particularly those by General Motors, such as select Chevrolet Colorado and GMC Canyon models, the 6x120 configuration supports the needs for stability and payload capacity in these vehicles. When selecting aftermarket wheels, it's essential to match the bolt pattern to ensure compatibility, as a mismatch can lead to unsafe conditions and potential damage to the vehicle. Additionally, the precise spacing and number of bolts in this pattern help to distribute the weight of the vehicle evenly across the wheel, supporting better handling, and optimizing performance.

6-Lug Pattern Torque Sequence
The lug bolt pattern torque sequence is a critical procedure designed to ensure that the wheel is mounted securely and uniformly on the vehicle's hub, preventing potential issues such as wheel vibration or hub damage. This sequence varies slightly depending on the number of lug bolts but always follows a pattern that promotes even distribution of force. When tightening lug nuts or bolts on a wheel with a 6-lug pattern, follow the torque sequence shown below to ensure even and secure tightening. The process usually involves multiple passes: initially tightening bolts to a lower torque setting to seat the wheel properly, followed by final tightening to the manufacturer's recommended torque specification using a calibrated torque wrench. Adhering to this sequence and using the correct torque ensures the wheel is balanced and securely attached, reducing the risk of brake rotor warping and ensuring the safety of the vehicle.
