Warning!! Do you have the factory Chrysler upper control arms on your Jeep Grand Cherokee? I want to notify my customers and owners of the WK/XK Jeeps (Grand Cherokee & Commander) If your Jeep is lifted and has over size tires, You may be at risk of losing a front tire!! In less than 2 weeks I got these disturbing picture emailed to me or sent to me on Facebook!! In both failures the ball joint separated from the factory Chrysler upper a-arm. Please check your ball joints!! Or up grade your factory Chrysler a-arms to my JBA upper a-arms for the lifted WK/XK!! http://jbaoffroad.com/jba-upper-a-arms-for-lifted-wk-xk-883.html I do not want your Jeep, to be the next one I see with the front tire under the Jeep. For peace of mind, Invest in a set of JBA a-arms!! http://jbaoffroad.com/jba-upper-a-arms-for-lifted-wk-xk-883.html Replace the factory Chrysler a-arms before it is too late!! If you already Invested in my JBA upper arms you made a wise choice!!
