Product Details

Bilstein B8 Pro upper control arms are designed for lifted Toyota 4Runner applications where factory geometry can lose caster and usable articulation. The tubular chromoly construction, sealed ball joints, and low-friction bushings work together to improve alignment range, steering stability, and suspension movement while keeping maintenance demands low.

These arms are a supporting geometry upgrade rather than a lift kit by themselves. An alignment is required after installation, and the benefit is greatest on vehicles whose ride height has been raised enough to push the factory upper control arm geometry outside its ideal range.
