Baja Kits Billet Upper Control Arms | Ford Bronco (2021-2025)

Baja Kits Billet Upper Control Arms

The Baja Kits Billet Upper Control Arms replace the factory ball-joint assembly with a high-angle uniball and strong CNC-machined billet structure. Added caster helps restore alignment and road manners after lifting, while the increased joint angle supports additional usable suspension travel.

Frequently Asked Questions

Why use uniballs instead of factory ball joints?
They provide increased angular range and strength for lifted, off-road suspension use, though they may transmit more noise or vibration.

Is an alignment required?
Yes. Any upper-control-arm replacement should be followed by a professional alignment.

Does this fit 2026?
Baja Kits’ current verified application ends at model year 2025.

Is the raw finish current?
Only the black-anodized configuration was verified; confirm raw-finish availability before ordering.
