SOLD OUT Teraflex - JK HD Ball Joints No Knurl

TeraFlex JK Heavy-Duty Ball Joints are engineered to handle the increased load caused by oversized tires and offset wheels. Fits all JK Wrangler models with Dana 30 or Dana 44 axles 


  • Extremely hard sintered wear bushings to handle extreme side load demands without failure 
  • Magnesium Phosphate coating to inhibit corrosion throughout 
  • Heat treated 4140 chromoly ball/stud and 1045 carbon steel housing 
  • Factory style serrated flange nut and grease fitting 


  • Hard alloy tool steel slotted wear plate for ball/stud to socket wear protection 
  • Wear plate features grease channels for increased flow through entire joint ensuring longevity and predictable operation 
  • Magnesium Phosphate coating to inhibit corrosion & friction throughout 
  • Heat treated 4140 chromoly ball/stud 
  • Huge 30mm (1.18”) ball 
  • Factory style serrated flanged castle nut 
  • Ball joint pre-load adjustability provides the end user with near effortless wear adjustment 
  • Low-profile single lip dust seal eliminates torn conventional dust boot concerns 
  • Adjustable ball stud retaining ring for accurate initial and future preload adjustments that can be done without any axle disassembly 
  • Adjustable preload can be performed with simple hand tools 
  • Adjustable end cap with two zerk fittings allow greasing access from either side w/out axle shaft removal even with larger RCV shafts 
  • Dual helical grease grooves machined in the retaining ring allow spent grease to exit through the low-profile seal 
  • Low-profile seal prevents contaminants, while allowing spent grease to evacuate from the ball joint 


  • 2 Upper Ball Joints
  • 2 Lower Ball joints


  • 2007-2018 JK Wrangler (2-door) 
  • 2007-2018 JKU Wrangler Unlimited (4-door)


  • 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.
