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 an 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 Chromoly steel. Combined with steel insert ensures that these ball joints are an industry leader in durability and strength.
These are a great upgrade from stock. I would definitely recommend these
These are knurled, which is a great thing considering I discovered that one of my knuckles is slightly ovaled from the old joints being broken. Get yourself the press kit, and lots of grease, when the other knuckles are not ovaled it takes effort to get these in. My front end feels nice and solid again, and I like that these are greasable.
I bought these for offroading because my other stock ones had broken, installing them was easy. I believe they are great product!
