The TeraFlex Dana 30/44 Heavy Duty Ball Joint Set has been designed to handle the increased stress caused by either oversized tires, or offset wheels. This is achieved because the upper ball joint incorporates hard sintered wear bushings to handle heavy side load demands without failure.
The lower ball joint has been designed with a threaded top cap for adjustable pre-load, and it allows grease servicing without removing the axle shaft, even with larger RCV shafts. These ball joints also feature a machined grease passage in the lower joint housing in the lower joint housing assembly which provides further lubrication access without affecting the ball joint load surface.
Additional features include:
• 1045 carbon steel housing with magnesium phosphate coated assembly
• 4140 chromoly ball/stud with magnesium phosphate anti-corrosion coating
• Factory style serrated flanged castle nut
• CR black neoprene boot
These ball joints will fit all JK Dana 30 and Dana 44 axles.
DOES fit Dynatrac ProRock Housing
*SOME 2012 and ALL newer Jeep Wranglers come factory with larger front axle shafts (Dana 30 & 44) than previous years, and will require grinding on the stub shaft forging parting line for clearance.
