This is an O.E.M. replacement part from Dana/Spicer.
Replaces rubber bushings with polyurethane and replaces the loose metal washers. Welded on metal washer is replaced with composite.
Using larger tires with soft O.E.M. rubber radius arm bushings causes the steering axis slant to change and premature failure of the control arm bushings occurs.
These help reduce common wheel "roll under" while braking and loss of steering control.
While braking they keep the front wheels and control arm assembly from literally rolling under the car!
A must use with larger tires.
