Product Description

The SPL FLCA S550 adjustable front lower control arm kit is designed for Ford Mustang S550 chassis (2015-23). It replaces the stock arms with billet aluminum units that allow camber, track-width, and roll-center adjustments. The high-quality spherical bearings eliminate bushing flex, providing sharper steering response and improved suspension articulation.

Installation involves removing the factory lower control arms, fitting the SPL units, setting alignment parameters, and performing a full wheel alignment. Roll-center spacers ensure proper geometry when the vehicle is lowered. Coverage is confirmed through 2023; verify fitment for GT350/GT350R/GT500 or modified setups.
