Compatibility
Fits hubs using a Wide 5 bolt pattern with 5/8 inch wheel studs. This is a different bolt pattern and larger diameter than the 11.625 in / 5 x 5 fan family (ALL42174/ALL42175/ALL42170/ALL42171). This is universal hub-mount hardware and is not vehicle-specific; confirm bolt pattern and stud size match your hub before ordering. This is the passenger-side (RH) fan; the driver-side counterpart is sold separately as ALL42172.
