Dr KDSS Front Billet Link for Toyota 4Runner (2010–2024), Lexus GX460 & Prado 150

Unlock the full potential of your KDSS suspension with the Dr KDSS Front Billet Link, a performance upgrade designed to eliminate the binding caused by the factory rubber bushing. CNC-machined from aircraft-grade billet aluminum and field-tested in real off-road environments, this upgraded front KDSS link allows smoother suspension movement, improved articulation, and more consistent sway bar operation when it matters most.
