Ball joints are massive compared to what I have now. I can tell they are built superior to any I’ve used before. Very easy to install

Great product even better customer service!! I was have an issue with one of my balljoints and emailed Keller performance at 9:30pm EST .. not only did Todd reply within minutes he knew exactly how to remedy my issue and added his personal phone number and said if I needed to call him that evening not to hesitate!! Now that’s customer service!!

Added these with my new Super ATV portal lifts and went straight to the mountains. No problems at all. Worth the extra coin!!
