Yukon Ball Joint Kit for Dana 30/44 & GM 8.25" Front Differentials, Both Sides

Upgrade your front-end durability with the Yukon YSPBJ-011HDK2 Ball Joint Kit. Designed for use with Dana 30, Dana 44, and GM 8.25″ front axle systems, this kit replaces both upper and lower ball joints on both sides. With forged steel housings, chromoly ball studs, greasable design, and full hardware included, it’s a heavy-duty solution for lifted trucks, rock rigs, or any vehicle needing robust steering joints.

What’s Inside the Kit

• 2 upper ball joints (left & right) 
• 2 lower ball joints (left & right) 
• Installation hardware — castle nuts, c-clips, cotter pins, and zerk grease fittings 

Key Features & Benefits

• Forged Steel Housings — Constructed from CNC machining of SAE 1045 carbon alloy steel for excellent strength and long life.
• Chromoly Ball Studs — Hot-forged, induction heat-treated 4140 chromoly ensures high durability under heavy loads and abuse. 
• Greaseable Design — Pre-threaded zerk housing allows regular lubrication, helping extend joint life.
• Dual-Boot Sealing — Synthetic neoprene outer boot plus an inner “pancake” seal protects internal components from contaminants. {index=7}
• Stronger Threads — Uses extrusion-rolled threads rather than cut, giving better fatigue resistance. 
• Lifetime Warranty — Covered against manufacturing defects. 

Applications & Fitment

• Compatible with Dana 30, Dana 44, and GM 8.25″ front differentials. 
• Both sides (left and right) — includes upper and lower units. 
• Often used in Jeep, GM, Ford, Dodge, IH Scout, and off-road rigs that use the above axle types. 

Important Notes & Install Tips

• Expect a break-in period (memory steer) for first 300–500 miles as new joints settle. 
• Ensure boots are seated properly before installing — improper sealing can lead to early failure.
• Regular greasing via the zerk fitting is recommended to extend life in dirty or wet use.
