Hub Rings

Used to assist alignment when mounting the wheel and eliminate damage to the stud holes when sliding a large, heavy wheel over studs or, assist alignment of the wheel to the threaded holes when fitting studs. The neat fit provided by the hub CBLs may assist with balancing of larger diameter, wide alloy wheels. CBLs are generally made of plastic as they do not carry load - this is the task of the wheel studs/nuts. If CBLs supplied with a set of wheels are not appropriate for an application, they should be discarded. However, greater care will be required to ensure the studs/nuts are correctly aligned and seated when fitting the wheel without a CBL, to eliminate damage and assist balancing.
