SPL Caster/Thrust/Tension rods provide a wide range of front or rear caster adjustment, allowing precise alignment for optimal turn-in response and to compensate for variances between left and right caster. Any changes to camber will change caster necessitating adjustable arms for a proper alignment. Low-friction, smooth articulating FK Spherical Bearings eliminate the stock mushy rubber bushing to provide a more responsive steering feel. Anti dive (when installed in the front) and anti squat (when installed in the rear) adjustment is achieved with Stainless Steel spacers for the forward mounting position of the trailing/caster arm, allowing you to raise or lower this pivot point and fine tune the balance of your car. These arms are designed to be used with the OEM or OEM style front or rear lower control arms.Our parts are engineered for maximum performance. Billet Aluminum alloy 2024 hex rods are precision CNC machined and gun drilled to reduce unsprung weight while maintaining high strength and stiffness. Our exclusive 360 degree Rotating Clamp design allows for easy access to quickly and precisely locking in your desired alignment settings. Long gone are the days of fumbling with wrenches to tighten jam nuts while trying to trying to keep your bearings oriented correctly. Blue Anodized Titanium hardware shaves even more unsprung weight from the arms and offers superior strength. These arms are designed for use in high performance street and race vehicles
