Teraflex JK HD Dana 44/30 Upper & Lower Ball Joint Set of 4 w/o 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.
These ball joints fit 2007-2018* JK Wrangler Dana 30 and Dana 44 axles.
