The arms are well-known for its high strength steel tube construction to withstand harshest off-road conditions. Its innovative tapered lock nut adjuster system help secure the rod ends to the slotted thread control arms when being tightened, keeping the adjusters from coming loose due to vibration or suspension flex. It also features harden rubber bushings for better handling response over the factory components. . Correct caster & pinion angle on lifted cars . High quality ultra strong steel construction .
