The configuration of lug holes on a wheel hub, essential for secure wheel mounting, is a crucial specification when replacing or upgrading wheels on vehicles manufactured by Arctic Cat. This measurement, typically expressed in millimeters, indicates the diameter of the circle formed by the centers of the lug holes and the number of lug holes present. For example, a “4×115” designation signifies a four-lug configuration with a circle diameter of 115mm.
Understanding this dimensional specification is paramount for ensuring compatibility between the wheel and the vehicle. Incorrect dimensions can lead to improper wheel fitment, resulting in compromised safety and potential damage to the vehicle’s suspension and drivetrain. Historically, variations in this specification have existed across different Arctic Cat models and model years, necessitating careful verification prior to any wheel modification or replacement. The correct specification ensures proper torque distribution and secure wheel attachment, contributing to vehicle stability and reliable performance under diverse operating conditions.
