Product Details: The Stemco 2 5/8-12" Thread Pro-Torque Spindle Nut is designed to minimize premature seal failure and improve seal and brake lining programs. This nut eliminates the potential for overtightening the jam nut and pushing the outer bearing cone out of position. With only one nut, you save time and effort trying to reposition multiple-nut assemblies. It is easy to install and provides a secure fit for your wheel end components. It is the perfect solution for any wheel end application. FleetPride is your First Click in Heavy Duty®.
