The Vertical Links - Billet Aluminum 15-16 Mustang by STEEDA AUTOSPORTS are precision-engineered suspension control arms designed for S550 platform enthusiasts seeking improved handling geometry and durability. These vertical links replace the factory lateral links and address a critical weak point in modern Mustang chassis dynamics—compliance under load that compromises corner entry precision and mid-corner stability.
STEEDA's billet aluminum construction eliminates the flex inherent in OEM stamped steel links, creating a rigid connection between the subframe and control arm pivot points that maintains consistent suspension geometry regardless of lateral g-forces or brake application. The material is significantly lighter than factory equivalents, contributing to unsprung weight reduction, while the precision-machined geometry ensures proper camber curves through the suspension travel window.
These vertical links are engineered exclusively for 2015–2016 Mustang models running the independent rear suspension, making them a foundational component for those building a track-focused S550 or upgrading a street Mustang for spirited driving. The design reduces bushing deflection, tightens steering feel, and improves tire contact patch consistency lap after lap.
