The Alloy USA 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 Chromolly steel. Combined with steel insert ensures that these ball joints are an industry leader in durability and strength.
You need to purchase a zerk needle type fitting so you can lube lower ball joints once installed,other than that these are some heavy duty ball joints,I'm happy with them
5.0Great quality and expect years of use
Very much improved over OEM ball joints, which started wearing out and causing front end to shimmy after only 25 thousand miles from new vehicle purchase. I expect these bushings will long outlast the OEM plastic bushings. Look forward to many years of useful service, especially since these also have zert fittings, which the OEM did not.
