Features, Description, Q&A
Tighten Up. Think about the relationship between the steering knuckle and the control arms. The knuckle needs to pivot as the wheels turn and the steering articulates. When you consider just how complicated that task is, it becomes apparent that the ball joints take on a lot of responsibility. Why let sloppy, tired, popping ball joints plague your Wrangler to kill comfort and performance?
Adjustable to Your Liking. It's all about the correct wheel alignment. Whether you're blasting trails, taking turns, or just cruising down the narrows, you want to make sure you're wheels are sitting at the right angle. There's only so much tweaking you can do with stock components. These adjustable ball joints change everything, though. They allow you to fine-tune your Wrangler's caster and camber for maximum performance at all angles.
Limited Lifetime Warranty. No, you're not going insane. These are trick aftermarket ball joints that are backed by a limited lifetime warranty. While you certainly want to make sure they're installed correctly and all greased up, you don't have to worry about defects standing in your way. For the lifetime of your Wrangler, you can count on Synergy standing behind its product.
Fitment. Fits 2007-2018 Jeep Wrangler JK models.
