        Stock replacement

        Replaced my stock ball joints on my 2014 JKU when it hit 66K miles, had a bad death wobble. Parts were as promised in add and the how video was a great help. Only difference in the video is some nut sizes on other parts that Ive replaced on the frontend vs whats in the video. Far as buying from Extreme Terrain, I wont shop anywhere else, every product Ive purchased is exactly what it says they are. Thank again for quality products.

        Great product

        This are very strong, you can easily tell the difference in these vs OEM. They work great for daily and off-roading. Can handle lifted with 35s.

        Far superior to stock

        This is clearly far superior to stock and feel very confident that it will last for many years. Just be cautious about the orientation of the lower grease points, if you point them the wrong way upon installation, you will not be able to service them

        Very sturdy

        I can definitely tell a difference in how tight the steering feels now.

        Ball Joints

        Wrapped up good. All parts were there. Went in without a hitch. Had them on or about a month and no problems at all

        1 2007 Rubicon - SCWBIGWHEELER


        When installing, the lower ball joints did not fit. With my Jeep up on the lift, I had to purchase new lowers from O'Rielly's. The "Lead-In" portion of the ball joints were .015 larger than the mounting hole. When contacting Alloy USA, they stated they checked stock and see no problem. I am stuck with a set of lower ball joints that are useless. Alloy USA does not believe there could be a problem even after I took a picture showing the oversize measurement. I will never purchase an Alloy USA product. BEWARE

        Nice ball joints

        Upper axels could be longer but the torque might be off. Waiting to see if they settle. Had to safety wire the nuts. Couldn’t get the whole cotter pin in.
