NOTE:

• We recommend Ball Joints w/out Knurls (# 3442002 or # 3440000) as they will not score the inner knuckle & open up the bore.

• We also offer Ball Joint w/ Knurls (# 3442022 or # 3440020) for ball joints that have a loose press fit in the inner knuckle due to repeated ball joint replacement or if knurled ball joints have been installed in the past.

These ball joints are awesome! I've replaced my ball joints twice over just 3 years of wheeling and daily driving. I finally purchased the Teraflex balljoints and could not be happier. I have 37 inch bead locked wheels, and it's been just about a year, and they are still nice and tight, and perform just like day one. I like that they are greasable and rebuild able. Another awesome product by Teraflex. Thanks!!

I installedthe Teraflex ball joints on my JKU! They have been holding up great with my 35's. I love the fact that I can rebuild them which will save me $$ in the long run!

Set has performed well for 20K miles. Took a leap of faith and self installed using T-Flex video instructions and all went well. Save $$ and borrow a ball press from a local auto supply store. Love that they can be rebuilt. Very happy with this purchase.
