The 9-inch, bolt-in–style axles satisfy the C-clip eliminator/aftermarket axles rule, per NHRA rulebook section 2:11 for cars 10.99 and quicker, or any car equipped with a spool regardless of class or e.t., and come with the required 5⁄8-inch wheel-stud minimum. The caliper mounting backing is added; then the bearing is pressed on, followed by an additional pressed-on bushing for added insurance. Make sure the open end of the bearing faces as shown so gear lube can get to the bearings. We shed the ABS rings and all the ABS components, going with a complete Strange braking system with a manual brakes master cylinder. This allowed us to also oust the power-steering components since we no longer needed the hydraboost for the brakes, losing over 100 pounds!
