The Alloy USA JK H/D ball joints have been designed with a low profile (grease) zerk fitting for regular maintenance, a feature not offered on factory replacement parts. Inner insert has been replaced with a high strength steel socket. (Replaces factory plastic nylon insert). This steel insert greatly increases ball joint strength and durability. This is a "Must" for lifted vehicles running any tire larger than stock applications. Ball and socket are assembled using an exclusive threaded preload system that insure precise tolerances for prolonged joint life and precise steering. Ball & shaft are constructed from industry leading SAE 4140 Chromolly steel. Combined with steel insert ensures that these ball joints are an industry leader in durability and strength.
From what I understand the comparable ball joints on the market do not have the same threaded preload feature and that is why you sometimes get steering that won't return to center like it should and has a break in period of X amount of miles. They use a different method of inserting and retaining the ball joint.
Upgrade your Ball Joints for your JK and or Jeep WJ!!

Id just like to say that I really had a bad experience with these ball joints. For my 97 ZJ (D30). For some reason, they would not torque down properly, difficult to press in, had slop in the joint right out of the box, and the boots were thin in my opinion. After having them in for about 1000 miles I got fed up and pressed them back out. I replaced them with a quality brand ball joint and I have not had a problem since.
If you have a 07-10 Jeep Wrangler JK and you notice a slight wobble while driving? Check your ball joints. When they are bad, contact us for your set of Alloy USA ball joints!! These are heavy duty, and come with a grease zerk fitting that you can't get on regular replacement parts. This is nice for maintainence.
