SKU: 4020

Hub nut locking is an important performance and safety concern for every desert racer.  In a time before the "wide ring", racers have experienced loosening of their hub and the assosiated spindle damage that comes along with this matter.  We have experienced this issue, first hand, with a variety of available products and due to the magnitude of this situation we set out to develop a more reliable positive locking system for performance race hubs.


Our hub nut locking arrangement comes with heavy duty grand national spindle nuts (1 right hand thread and 1 left hand thread) that is drilled and tapped to securely fix the 4130 wide ring with socket head screws.



Nut application - grand national

Wide ring thickness - .188"

Wide ring material - 4130 chromoly steel

Total unit thickness (bearing face to outside of screw head) - .930"


*sold as axle set

**please make sure that there is room for the total thickness as some hubs will not allow this dimension
