Teraflex HD Wear Adjustable Upper Ball Joints (21-26 Bronco)Find parts that fit my vehicle

When your Bronco takes the hard line, these joints take the hit. TeraFlex HD Adjustable Upper Ball Joints are built for drivers who expect more than stock durability - combining precise engineering with trail-tested grit for unmatched performance on and off the road.

The large 30 mm metal-on-metal joint rides on a heat-treated chromoly stud and 1045 carbon-steel housing that shrugs off punishment. Dual helical grease grooves purge out grit with every pump, while the low-profile seal locks out contaminants for long, quiet service life.

Adjustable for wear and fully greaseable on-vehicle - no teardown required - these joints deliver smoother steering feel, improved alignment control, and articulation up to 94° for lifted or flex-heavy builds. Zinc-iron coating resists corrosion from mud, salt, and seasons of abuse.

Whether you’re crawling rock, carving dunes, or driving daily, TeraFlex HD Ball Joints keep your Bronco precise, predictable, and ready for whatever the trail throws next. Engineered to endure with trail-proven precision.
