Hub Dynamic Capacities
NOTE:
Hub dynamic capacity is based on the weight-bearing capacity of the wheel bearings. Non-standard wheel offsets or special
applications may affect the weight-bearing capacity of a hub.
Please consult with KIC customer service and wheel supplier when using non-standard wheel offsets or with off-highway ap-
plications to determine total weight-bearing capacity of a hub.
