• Heat treated 4140 chromoly ball/stud & 1045 carbon steel housing
• Factory style serrated flange nut & grease fitting

LOWER BALL JOINT FEATURES:
• 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 & 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 w/ near effortless wear adjustment (kit includes Preload Adjustment Tool)
• Low-profile single lip dust seal eliminates torn conventional dust boot concerns
• Adjustable ball stud retaining ring for accurate initial & future preload adjustments that can be done w/out any axle disassembly
• Adjustable preload can be performed w/ simple hand tools
• Adjustable end cap w/ (2) zerk fittings (“Frog Eye”) allow greasing access from either side w/out axle shaft removal
• 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
• These ball joints w/ knurls (# 1355300) are for ball joints w/ 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.
• We recommend ball joints w/out knurls (# 1355100) as they will not score the inner knuckle and open up the bore.
INSTALL TIME: 4 Hours
