SPL Front Lower Control Arms – Shelby GT350 / GT350R
The SPL Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the Shelby GT350 and GT350R. Precision-engineered using billet aluminum, stainless steel, chromoly steel, and titanium, these arms are not only stronger than OEM but also 2 lbs lighter per side.
Designed for both street and track, these arms allow you to run more negative camber for maximum grip and reduced outer tire wear—essential when running upgraded tires. Tested on the Vorshlag Dark Horse, these arms have proven to drop lap times by several seconds.
Each kit includes a ride height sensor bracket to maintain correct factory sensor operation, no matter the arm length.
