Jeep ball joints
This complete 4 piece upper and lower ball joint kit fits 99-04 Jeep Wrangler JL, JK, TJ and Grand Cherokee WJ.
These HD ball joint kits have been designed with a low profile (greased) zerk fitting, a feature not found in factory replacements. The internal insert is replaced by a high-strength steel grip, effectively replacing the stock plastic/nylon insert.
This steel insert increases the strength of the ball joint. This is a must-have feature for lift trucks with larger-than-stock tyres. The ball and socket use a unique threaded preload system that extends the life of the joint. The ball joint is made of SAE 4150 Chromoly steel.
