Teraflex JK HD Dana 44/30 Upper & Lower Ball Joint Kit w/ Knurl

TeraFlex HD ball joints are engineered to handle the increased load caused by oversized tires and offset wheels. The upper ball joint incorporates hard sintered wear bushings to handle extreme side load demands without failure. The lower ball joint features a threaded top cap for adjustable preload and allows grease servicing without axle shaft removal, even with larger RCV shafts. A machined grease passage in the lower joint housing assembly provides lubrication access without affecting the ball joint load surface. 

Upper ball joint features

Note: Fits JK Wrangler Dana 30 & Dana 44 axles. We recommend ball joints without knurls as they will not score the inner knuckle and open up the bore. We also offer ball joint with knurls for ball joints that have a loose press fit in the inner knuckle due to repeated ball joint replacement or if knurled ball joints have been installed in the past.
