Wallowed out an OEM rear knuckle after a hard landing in the desert. Put these billet units on and the rear end feels completely transformed — tight and confidence-inspiring. Direct bolt-in made the install straightforward. — John D., Arizona
The sealed bearing carrier is the feature that sold me. My OEM bearings were constantly contaminated from mud riding. Two seasons on these knuckles and the bearings are still clean and tight. — Sarah K., Utah
